CVSS v3.1 |
| A remote denial-of-service vulnerability exists in the ZTE Cloud PC client uSmartview, which may lead to memory corruption and remote denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: qla2xxx: Completely fix fcport double free
In qla24xx_els_dcmd_iocb() sp->free is set to qla2x00_els_dcmd_sp_free().
When an error happens, this function is called by qla2x00_sp_release(),
when kref_put() releases the first and the last reference.
qla2x00_els_dcmd_sp_free() frees fcport by calling qla2x00_free_fcport().
Doing it one more time after kref_put() is a bad idea. |
| In the Linux kernel, the following vulnerability has been resolved:
net: mana: Fix double destroy_workqueue on service rescan PCI path
While testing corner cases in the driver, a use-after-free crash
was found on the service rescan PCI path.
When mana_serv_reset() calls mana_gd_suspend(), mana_gd_cleanup()
destroys gc->service_wq. If the subsequent mana_gd_resume() fails
with -ETIMEDOUT or -EPROTO, the code falls through to
mana_serv_rescan() which triggers pci_stop_and_remove_bus_device().
This invokes the PCI .remove callback (mana_gd_remove), which calls
mana_gd_cleanup() a second time, attempting to destroy the already-
freed workqueue. Fix this by NULL-checking gc->service_wq in
mana_gd_cleanup() and setting it to NULL after destruction.

| In the Linux kernel, the following vulnerability has been resolved:
usb: ulpi: fix double free in ulpi_register_interface() error path
When device_register() fails, ulpi_register() calls put_device() on
ulpi->dev.
The device release callback ulpi_dev_release() drops the OF node
reference and frees ulpi, but the current error path in
ulpi_register_interface() then calls kfree(ulpi) again, causing a
double free.
Let put_device() handle the cleanup through ulpi_dev_release() and
avoid freeing ulpi again in ulpi_register_interface(). |
| In the Linux kernel, the following vulnerability has been resolved:
net/x25: Fix potential double free of skb
When alloc_skb fails in x25_queue_rx_frame it calls kfree_skb(skb) at
line 48 and returns 1 (error).
This error propagates back through the call chain:
x25_queue_rx_frame returns 1
|
v
x25_state3_machine receives the return value 1 and takes the else
branch at line 278, setting queued=0 and returning 0
|
v
x25_process_rx_frame returns queued=0
|
v
x25_backlog_rcv at line 452 sees queued=0 and calls kfree_skb(skb)
again
This would free the same skb twice. Looking at x25_backlog_rcv:
net/x25/x25_in.c:x25_backlog_rcv() {
...
queued = x25_process_rx_frame(sk, skb);
...
if (!queued)
kfree_skb(skb);

| In the Linux kernel, the following vulnerability has been resolved:
reset: gpio: fix double free in reset_add_gpio_aux_device() error path
When __auxiliary_device_add() fails, reset_add_gpio_aux_device()
calls auxiliary_device_uninit(adev).
The device release callback reset_gpio_aux_device_release() frees
adev, but the current error path then calls kfree(adev) again,
causing a double free.
Keep kfree(adev) for the auxiliary_device_init() failure path, but
avoid freeing adev after auxiliary_device_uninit(). |
| In the Linux kernel, the following vulnerability has been resolved:
misc: fastrpc: possible double-free of cctx->remote_heap
fastrpc_init_create_static_process() may free cctx->remote_heap on the
err_map path but does not clear the pointer. Later, fastrpc_rpmsg_remove()
frees cctx->remote_heap again if it is non-NULL, which can lead to a
double-free if the INIT_CREATE_STATIC ioctl hits the error path and the rpmsg
device is subsequently removed/unbound.
Clear cctx->remote_heap after freeing it in the error path to prevent the
later cleanup from freeing it again.
This issue was found by an in-house analysis workflow that extracts AST-based
information and runs static checks, with LLM assistance for triage, and was
confirmed by manual code review.
No hardware testing was performed. |
| In the Linux kernel, the following vulnerability has been resolved:
xfrm: iptfs: only publish mode_data after clone setup
iptfs_clone_state() stores x->mode_data before allocating the reorder
window. If that allocation fails, the code frees the cloned state and
returns -ENOMEM, leaving x->mode_data pointing at freed memory.
The xfrm clone unwind later runs destroy_state() through x->mode_data,
so the failed clone path tears down IPTFS state that clone_state()
already freed.
Keep the cloned IPTFS state private until all allocations succeed so
failed clones leave x->mode_data unset. The destroy path already
handles a NULL mode_data pointer. |
| Double Free and possible RCE vulnerability in Apache HTTP Server with the HTTP/2 protocol.
This issue affects Apache HTTP Server: 2.4.66.
Users are recommended to upgrade to version 2.4.67, which fixes the issue. |
| Notepad++ 8.9.3 contains a format string injection vulnerability in the Find Results panel handler that allows attackers to cause denial of service and information disclosure by crafting a malicious nativeLang.xml language pack file. Attackers can distribute a poisoned language pack through community channels that triggers format string interpretation when a user performs search operations, leading to access violations and potential leakage of stack or register contents. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: server: avoid double-free in smb_direct_free_sendmsg after smb_direct_flush_send_list()
smb_direct_flush_send_list() already calls smb_direct_free_sendmsg(),
so we should not call it again after post_sendmsg()
moved it to the batch list. |
| In the Linux kernel, the following vulnerability has been resolved:
smb: client: avoid double-free in smbd_free_send_io() after smbd_send_batch_flush()
smbd_send_batch_flush() already calls smbd_free_send_io(),
so we should not call it again after smbd_post_send()
moved it to the batch list. |
| In the Linux kernel, the following vulnerability has been resolved:
net: bcmasp: fix double free of WoL irq
We do not need to free wol_irq since it was instantiated with
devm_request_irq(). So devres will free for us. |
| Successful exploitation of the
string injection vulnerability could allow an attacker to obtain memory address
information or crash the application. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: always free skb on ieee80211_tx_prepare_skb() failure
ieee80211_tx_prepare_skb() has three error paths, but only two of them
free the skb. The first error path (ieee80211_tx_prepare() returning
TX_DROP) does not free it, while invoke_tx_handlers() failure and the
fragmentation check both do.
Add kfree_skb() to the first error path so all three are consistent,
and remove the now-redundant frees in callers (ath9k, mt76,
mac80211_hwsim) to avoid double-free.
Document the skb ownership guarantee in the function's kdoc. |
| In the Linux kernel, the following vulnerability has been resolved:
pinctrl: cirrus: cs42l43: Fix double-put in cs42l43_pin_probe()
devm_add_action_or_reset() already invokes the action on failure,
so the explicit put causes a double-put. |
| In the Linux kernel, the following vulnerability has been resolved:
apparmor: Fix double free of ns_name in aa_replace_profiles()
if ns_name is NULL after
1071 error = aa_unpack(udata, &lh, &ns_name);
and if ent->ns_name contains an ns_name in
1089 } else if (ent->ns_name) {
then ns_name is assigned the ent->ns_name
1095 ns_name = ent->ns_name;
however ent->ns_name is freed at
1262 aa_load_ent_free(ent);
and then again when freeing ns_name at
1270 kfree(ns_name);
Fix this by NULLing out ent->ns_name after it is transferred to ns_name

| Format string vulnerability in BMC PATROL Agent before 3.7.30 allows remote attackers to execute arbitrary code via format string specifiers in an invalid version number to TCP port 3181, which are not properly handled when writing a log message. |
| Format string vulnerability in the mini_calendar component in Citadel.org WebCit 7.22, and other versions before 7.39, allows remote attackers to execute arbitrary code via unspecified vectors. |
| The Platform Service Process (asampsp) in Fan-Out Driver Platform Services for Novell Identity Manager (IDM) 3.5.1 allows remote attackers to cause a denial of service (daemon crash) via unspecified network traffic that triggers a syslog message containing invalid format string specifiers, as demonstrated by a Nessus scan. |
