CVE-2026-2804 1 Mozilla 2 Firefox, Thunderbird 2026-04-15 5.4 Medium
Use-after-free in the JavaScript: WebAssembly component. This vulnerability was fixed in Firefox 148 and Thunderbird 148.
CVE-2026-23234 1 Linux 1 Linux Kernel 2026-04-15 7.8 High
In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to avoid UAF in f2fs_write_end_io() As syzbot reported an use-after-free issue in f2fs_write_end_io(). It is caused by below race condition: loop device umount - worker_thread - loop_process_work - do_req_filebacked - lo_rw_aio - lo_rw_aio_complete - blk_mq_end_request - blk_update_request - f2fs_write_end_io - dec_page_count - folio_end_writeback - kill_f2fs_super - kill_block_super - f2fs_put_super : free(sbi) : get_pages(, F2FS_WB_CP_DATA) accessed sbi which is freed In kill_f2fs_super(), we will drop all page caches of f2fs inodes before call free(sbi), it guarantee that all folios should end its writeback, so it should be safe to access sbi before last folio_end_writeback(). Let's relocate ckpt thread wakeup flow before folio_end_writeback() to resolve this issue.
CVE-2026-3847 1 Mozilla 1 Firefox 2026-04-15 8.8 High
Memory safety bugs present in Firefox 148.0.2. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability was fixed in Firefox 148.0.2.
CVE-2026-27854 1 Powerdns 1 Dnsdist 2026-04-15 4.8 Medium
An attacker might be able to trigger a use-after-free by sending crafted DNS queries to a DNSdist using the DNSQuestion:getEDNSOptions method in custom Lua code. In some cases DNSQuestion:getEDNSOptions might refer to a version of the DNS packet that has been modified, thus triggering a use-after-free and potentially a crash resulting in denial of service.
CVE-2026-3777 4 Apple, Foxit, Foxitsoftware and 1 more 6 Macos, Pdf Editor, Pdf Reader and 3 more 2026-04-15 5.5 Medium
The application does not properly validate the lifetime and validity of internal view cache pointers after JavaScript changes the document zoom and page state. When a script modifies the zoom property and then triggers a page change, the original view object may be destroyed while stale pointers are still kept and later dereferenced, which under crafted JavaScript and document structures can lead to a use-after-free condition and potentially allow arbitrary code execution.
CVE-2026-5877 4 Apple, Google, Linux and 1 more 4 Macos, Chrome, Linux Kernel and 1 more 2026-04-15 8.8 High
Use after free in Navigation in Google Chrome prior to 147.0.7727.55 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: Medium)
CVE-2026-34734 1 Hdfgroup 1 Hdf5 2026-04-15 7.8 High
HDF5 is software for managing data. In 1.14.1-2 and earlier, a heap-use-after-free was found in the h5dump helper utility. An attacker who can supply a malicious h5 file can trigger a heap use-after-free. The freed object is referenced in a memmove call from H5T__conv_struct. The original object was allocated by H5D__typeinfo_init_phase3 and freed by H5D__typeinfo_term.
CVE-2026-34983 1 Bytecodealliance 1 Wasmtime 2026-04-15 5.0 Medium
Wasmtime is a runtime for WebAssembly. In 43.0.0, cloning a wasmtime::Linker is unsound and can result in use-after-free bugs. This bug is not controllable by guest Wasm programs. It can only be triggered by a specific sequence of embedder API calls made by the host. Specifically, the following steps must occur to trigger the bug clone a wasmtime::Linker, drop the original linker instance, use the new, cloned linker instance, resulting in a use-after-free. This vulnerability is fixed in 43.0.1.
CVE-2011-10034 1 Irai 1 Automgen 2026-04-15 N/A
AUTOMGEN versions up to and including 8.0.0.7 (also referenced as 8.022) contain a vulnerability in that project file handling frees an object and subsequently dereferences the stale pointer when processing certain malformed fields. The dangling-pointer use enables an attacker to influence an indirect call through attacker-controlled memory, resulting in denial-of-service. In some conditions, remote code execution may be possible.
CVE-2025-65953 1 Emqx 1 Nanomq 2026-04-15 N/A
NanoMQ MQTT Broker (NanoMQ) is an all-around Edge Messaging Platform. Prior to version 0.22.5, a Heap-Use-After-Free (UAF) vulnerability exists in the TCP transport component of NanoMQ, which relies on the underlying NanoNNG library (specifically in src/sp/transport/mqtt/broker_tcp.c). The vulnerability is due to improper resource management and premature cleanup of message and pipe structures under specific malformed MQTTV5 retain message traffic conditions. This issue has been patched in version 0.22.5.
CVE-2025-9157 1 Appneta 1 Tcpreplay 2026-04-15 5.3 Medium
A vulnerability was determined in appneta tcpreplay up to 4.5.2-beta2. The impacted element is the function untrunc_packet of the file src/tcpedit/edit_packet.c of the component tcprewrite. Executing manipulation can lead to use after free. It is possible to launch the attack on the local host. The exploit has been publicly disclosed and may be utilized. This patch is called 73008f261f1cdf7a1087dc8759115242696d35da. Applying a patch is advised to resolve this issue.
CVE-2024-38375 1 Fastly 1 Js-compute 2026-04-15 5.3 Medium
@fastly/js-compute is a JavaScript SDK and runtime for building Fastly Compute applications. The implementation of several functions were determined to include a use-after-free bug. This bug could allow for unintended data loss if the result of the preceding functions were sent anywhere else, and often results in a guest trap causing services to return a 500. This bug has been fixed in version 3.16.0 of the `@fastly/js-compute` package.
CVE-2025-23115 2026-04-15 N/A
A Use After Free vulnerability on UniFi Protect Cameras could allow a Remote Code Execution (RCE) by a malicious actor with access to UniFi Protect Cameras management network.
CVE-2024-40885 1 Intel 1 M20ntp Firmware 2026-04-15 7.5 High
Use after free in the UEFI firmware of some Intel(R) Server M20NTP BIOS may allow a privileged user to potentially enable escalation of privilege via local access.
CVE-2024-47892 2026-04-15 7.8 High
Software installed and run as a non-privileged user may conduct GPU system calls to read and write freed physical memory from the GPU.
CVE-2025-49014 1 Jqlang 1 Jq 2026-04-15 5.3 Medium
jq is a command-line JSON processor. In version 1.8.0 a heap use after free vulnerability exists within the function f_strflocaltime of /src/builtin.c. This issue has been patched in commit 499c91b, no known fix version exists at time of publication.
CVE-2024-47891 2026-04-15 7.8 High
Software installed and run as a non-privileged user may conduct improper GPU system calls to trigger use-after-free kernel exceptions.
CVE-2023-5447 2026-04-15 5.5 Medium
Missing lock check in SynHsaService may create a use-after-free condition which causes abnormal termination of the service, resulting in denial of service for the Synaptics Hardware Support App.
CVE-2025-48945 2026-04-15 5.5 Medium
pycares is a Python module which provides an interface to c-ares. c-ares is a C library that performs DNS requests and name resolutions asynchronously. Prior to version 4.9.0, pycares is vulnerable to a use-after-free condition that occurs when a Channel object is garbage collected while DNS queries are still pending. This results in a fatal Python error and interpreter crash. The vulnerability has been fixed in pycares 4.9.0 by implementing a safe channel destruction mechanism.
CVE-2025-50518 1 Libcoap 1 Libcoap 2026-04-15 9.8 Critical
A use-after-free vulnerability exists in the coap_delete_pdu_lkd function within coap_pdu.c of the libcoap library. This issue occurs due to improper handling of memory after the freeing of a PDU object, leading to potential memory corruption or the possibility of executing arbitrary code. NOTE: this is disputed by the Supplier because it only occurs when an application uses libcoap incorrectly.
