| CVE-2026-46159 | 1 Linux | 1 Linux Kernel | 2026-05-28 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: btrfs: fix btrfs_ioctl_space_info() slot_count TOCTOU which can lead to info-leak btrfs_ioctl_space_info() has a TOCTOU race between two passes over the block group RAID type lists. The first pass counts entries to determine the allocation size, then the second pass fills the buffer. The groups_sem rwlock is released between passes, allowing concurrent block group removal to reduce the entry count. When the second pass fills fewer entries than the first pass counted, copy_to_user() copies the full alloc_size bytes including trailing uninitialized kmalloc bytes to userspace. Fix by copying only total_spaces entries (the actually-filled count from the second pass) instead of alloc_size bytes, and switch to kzalloc so any future copy size mismatch cannot leak heap data. | ||||
| CVE-2026-46158 | 1 Linux | 1 Linux Kernel | 2026-05-28 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: mptcp: pm: ADD_ADDR rtx: always decrease sk refcount When an ADD_ADDR is retransmitted, the sk is held in sk_reset_timer(). It should then be released in all cases at the end. Some (unlikely) checks were returning directly instead of calling sock_put() to decrease the refcount. Jump to a new 'exit' label to call __sock_put() (which will become sock_put() in the next commit) to fix this potential leak. While at it, drop the '!msk' check which cannot happen because it is never reset, and explicitly mark the remaining one as "unlikely". | ||||
| CVE-2026-46157 | 1 Linux | 1 Linux Kernel | 2026-05-28 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ALSA: pcm: oss: Fix data race at accessing runtime.oss.trigger Currently the runtime.oss.trigger field may be accessed concurrently without protection, which may lead to the data race. And, in this case, it may lead to more severe problem because it's a bit field; as writing the data, it may overwrite other bit fields as well, which confuses the operation completely, as spotted by fuzzing. Fix it by covering runtime.oss.trigger bit fled also with the existing params_lock mutex in both snd_pcm_oss_get_trigger() and snd_pcm_oss_poll(). | ||||

| CVE-2026-46155 | 1 Linux | 1 Linux Kernel | 2026-05-28 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: smb/client: fix out-of-bounds read in smb2_compound_op() If a server sends a truncated response but a large OutputBufferLength, and terminates the EA list early, check_wsl_eas() returns success without validating that the entire OutputBufferLength fits within iov_len. Then smb2_compound_op() does: memcpy(idata->wsl.eas, data[0], size[0]); Where size[0] is OutputBufferLength. If iov_len is smaller than size[0], memcpy can read beyond the end of the rsp_iov allocation and leak adjacent kernel heap memory. | ||||
| CVE-2026-46154 | 1 Linux | 1 Linux Kernel | 2026-05-28 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: sched_ext: Read scx_root under scx_cgroup_ops_rwsem in cgroup setters scx_group_set_{weight,idle,bandwidth}() cache scx_root before acquiring scx_cgroup_ops_rwsem, so the pointer can be stale by the time the op runs. If the loaded scheduler is disabled and freed (via RCU work) and another is enabled between the naked load and the rwsem acquire, the reader sees scx_cgroup_enabled=true (the new scheduler's) but dereferences the freed one - UAF on SCX_HAS_OP(sch, ...) / SCX_CALL_OP(sch, ...). scx_cgroup_enabled is toggled only under scx_cgroup_ops_rwsem write (scx_cgroup_{init,exit}), so reading scx_root inside the rwsem read section correlates @sch with the enabled snapshot. | ||||
| CVE-2026-46153 | 1 Linux | 1 Linux Kernel | 2026-05-28 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: 8021q: delete cleared egress QoS mappings vlan_dev_set_egress_priority() currently keeps cleared egress priority mappings in the hash as tombstones. Repeated set/clear cycles with distinct skb priorities therefore accumulate mapping nodes until device teardown and leak memory. Delete mappings when vlan_prio is cleared instead of keeping tombstones. Now that the egress mapping lists are RCU protected, the node can be unlinked safely and freed after a grace period. | ||||
| CVE-2026-46152 | 1 Linux | 1 Linux Kernel | 2026-05-28 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: drop stray 'static' from fast-RX rx_result ieee80211_invoke_fast_rx() is documented as safe for parallel RX, but its per-invocation rx_result is declared static. Concurrent callers then share one instance and can overwrite each other's result between ieee80211_rx_mesh_data() and the switch on res. That can make a packet that was queued or consumed by ieee80211_rx_mesh_data() fall through into ieee80211_rx_8023(), or make a packet that should continue return as queued. Make res an automatic variable so each invocation keeps its own result. | ||||
| CVE-2026-46151 | 1 Linux | 1 Linux Kernel | 2026-05-28 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: usb: usblp: fix heap leak in IEEE 1284 device ID via short response usblp_ctrl_msg() collapses the usb_control_msg() return value to 0/-errno, discarding the actual number of bytes transferred. A broken printer can complete the GET_DEVICE_ID control transfer short and the driver has no way to know. usblp_cache_device_id_string() reads the 2-byte big-endian length prefix from the response and trusts it (clamped only to the buffer bounds). The buffer is kmalloc(1024) at probe time. A device that sends exactly two bytes (e.g. 0x03 0xFF, claiming a 1023-byte ID) leaves device_id_string[2..1022] holding stale kmalloc heap. That stale data is then exposed: - via the ieee1284_id sysfs attribute (sprintf("%s", buf+2), truncated at the first NUL in the stale heap), and - via the IOCNR_GET_DEVICE_ID ioctl, which copy_to_user()s the full claimed length regardless of NULs, up to 1021 bytes of uninitialized heap, with the leak size chosen by the device. Fix this up by just zapping the buffer with zeros before each request sent to the device. | ||||
| CVE-2026-46150 | 1 Linux | 1 Linux Kernel | 2026-05-28 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: fanotify: fix false positive on permission events fsnotify_get_mark_safe() may return false for a mark on an unrelated group, which results in bypassing the permission check. Fix by skipping over detached marks that are not in the current group. | ||||
| CVE-2026-46149 | 1 Linux | 1 Linux Kernel | 2026-05-28 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: scsi: target: configfs: Bound snprintf() return in tg_pt_gp_members_show() target_tg_pt_gp_members_show() formats LUN paths with snprintf() into a 256-byte stack buffer, then will memcpy() cur_len bytes from that buffer. snprintf() returns the length the output would have had, which can exceed the buffer size when the fabric WWN is long because iSCSI IQN names can be up to 223 bytes. The check at the memcpy() site only guards the destination page write, not the source read, so memcpy() will read past the stack buffer and copy adjacent stack contents to the sysfs reader, which when CONFIG_FORTIFY_SOURCE is enabled, fortify_panic() will be triggered. Commit 27e06650a5ea ("scsi: target: target_core_configfs: Add length check to avoid buffer overflow") added the same bound to the target_lu_gp_members_show() but the tg_pt_gp variant was missed so resolve that here. | ||||
| CVE-2026-46148 | 1 Linux | 1 Linux Kernel | 2026-05-28 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: spi: microchip-core-qspi: control built-in cs manually The coreQSPI IP supports only a single chip select, which is automagically operated by the hardware - set low when the transmit buffer first gets written to and set high when the number of bytes written to the TOTALBYTES field of the FRAMES register have been sent on the bus. Additional devices must use GPIOs for their chip selects. It was reported to me that if there are two devices attached to this QSPI controller that the in-built chip select is set low while linux tries to access the device attached to the GPIO. This went undetected as the boards that connected multiple devices to the SPI controller all exclusively used GPIOs for chip selects, not relying on the built-in chip select at all. It turns out that this was because the built-in chip select, when controlled automagically, is set low when active and high when inactive, thereby ruling out its use for active-high devices or devices that need to transmit with the chip select disabled. Modify the driver so that it controls chip select directly, retaining the behaviour for mem_ops of setting the chip select active for the entire duration of the transfer in the exec_op callback. For regular transfers, implement the set_cs callback for the core to use. As part of this, the existing setup callback, mchp_coreqspi_setup_op(), is removed. Modifying the CLKIDLE field is not safe to do during operation when there are multiple devices, so this code is removed entirely. Setting the MASTER and ENABLE fields is something that can be done once at probe, it doesn't need to be re-run for each device. Instead the new setup callback sets the built-in chip select to its inactive state for active-low devices, as the reset value of the chip select in software controlled mode is low. | ||||
| CVE-2026-46147 | 1 Linux | 1 Linux Kernel | 2026-05-28 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Fix pin leak and publication ordering in __pkvm_init_vcpu() Two bugs exist in the vCPU initialisation path: 1. If a check fails after hyp_pin_shared_mem() succeeds, the cleanup path jumps to 'unlock' without calling unpin_host_vcpu() or unpin_host_sve_state(), permanently leaking pin references on the host vCPU and SVE state pages. Extract a register_hyp_vcpu() helper that performs the checks and the store. When register_hyp_vcpu() returns an error, call unpin_host_vcpu() and unpin_host_sve_state() inline before falling through to the existing 'unlock' label. 2. register_hyp_vcpu() publishes the new vCPU pointer into 'hyp_vm->vcpus[]' with a bare store, allowing a concurrent caller of pkvm_load_hyp_vcpu() to observe a partially initialised vCPU object. Ensure the store uses smp_store_release() and the load uses smp_load_acquire(). While 'vm_table_lock' currently serialises the store and the load, these barriers ensure the reader sees the fully initialised 'hyp_vcpu' object even if there were a lockless path or if the lock's own ordering guarantees were insufficient for nested object initialization. | ||||
| CVE-2026-46146 | 1 Linux | 1 Linux Kernel | 2026-05-28 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Avoid potential endless loop in convert_chmap_v3() The convert_chmap_v3() has a loop with its increment size of cs_desc->wLength, but we forgot to validate cs_desc->wLength itself, which may lead to potential endless loop by a malformed descriptor. Add a proper size check to abort the loop for plugging the hole. | ||||
| CVE-2026-46145 | 1 Linux | 1 Linux Kernel | 2026-05-28 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: RDMA/mana: Validate rx_hash_key_len Sashiko points out that rx_hash_key_len comes from a uAPI structure and is blindly passed to memcpy, allowing the userspace to trash kernel memory. Bounds check it so the memcpy cannot overflow. | ||||

| In the Linux kernel, the following vulnerability has been resolved: net: libwx: fix VF illegal register access Register WX_CFG_PORT_ST is a PF restricted register. When a VF is initialized, attempting to read this register triggers an illegal register access, which lead to a system hang. When the device is VF, the bus function ID can be obtained directly from the PCI_FUNC(pdev->devfn). | ||||

| In the Linux kernel, the following vulnerability has been resolved: powerpc/xive: fix kmemleak caused by incorrect chip_data lookup The kmemleak reports the following memory leak: Unreferenced object 0xc0000002a7fbc640 (size 64): comm "kworker/8:1", pid 540, jiffies 4294937872 hex dump (first 32 bytes): 01 00 00 00 00 00 00 00 00 00 09 04 00 04 00 00 ................ 00 00 a7 81 00 00 0a c0 00 00 08 04 00 04 00 00 ................ backtrace (crc 177d48f6): __kmalloc_cache_noprof+0x520/0x730 xive_irq_alloc_data.constprop.0+0x40/0xe0 xive_irq_domain_alloc+0xd0/0x1b0 irq_domain_alloc_irqs_parent+0x44/0x6c pseries_irq_domain_alloc+0x1cc/0x354 irq_domain_alloc_irqs_parent+0x44/0x6c msi_domain_alloc+0xb0/0x220 irq_domain_alloc_irqs_locked+0x138/0x4d0 __irq_domain_alloc_irqs+0x8c/0xfc __msi_domain_alloc_irqs+0x214/0x4d8 msi_domain_alloc_irqs_all_locked+0x70/0xf8 pci_msi_setup_msi_irqs+0x60/0x78 __pci_enable_msix_range+0x54c/0x98c pci_alloc_irq_vectors_affinity+0x16c/0x1d4 nvme_pci_enable+0xac/0x9c0 [nvme] nvme_probe+0x340/0x764 [nvme] This occurs when allocating MSI-X vectors for an NVMe device. During allocation the XIVE code creates a struct xive_irq_data and stores it in irq_data->chip_data. When the MSI-X irqdomain is later freed, xive_irq_free_data() is responsible for retrieving this structure and freeing it. However, after commit cc0cc23babc9 ("powerpc/xive: Untangle xive from child interrupt controller drivers"), xive_irq_free_data() retrieves the chip_data using irq_get_chip_data(), which looks up the data through the child domain. This is incorrect because the XIVE-specific irq data is associated with the XIVE (parent) domain. As a result the lookup fails and the allocated struct xive_irq_data is never freed, leading to the kmemleak report shown above. Fix this by retrieving the irq_data from the correct domain using irq_domain_get_irq_data() and then accessing the chip_data via irq_data_get_irq_chip_data(). | ||||
| CVE-2026-46140 | 1 Linux | 1 Linux Kernel | 2026-05-28 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: Bluetooth: btmtk: validate WMT event SKB length before struct access btmtk_usb_hci_wmt_sync() casts the WMT event response SKB data to struct btmtk_hci_wmt_evt (7 bytes) and struct btmtk_hci_wmt_evt_funcc (9 bytes) without first checking that the SKB contains enough data. A short firmware response causes out-of-bounds reads from SKB tailroom. Use skb_pull_data() to validate and advance past the base WMT event header. For the FUNC_CTRL case, pull the additional status field bytes before accessing them. | ||||
