CVE-2024-45063 1 Freebsd 1 Freebsd 2025-11-04 9.8 Critical
The function ctl_write_buffer incorrectly set a flag which resulted in a kernel Use-After-Free when a command finished processing. Malicious software running in a guest VM that exposes virtio_scsi can exploit the vulnerabilities to achieve code execution on the host in the bhyve userspace process, which typically runs as root. Note that bhyve runs in a Capsicum sandbox, so malicious code is constrained by the capabilities available to the bhyve process. A malicious iSCSI initiator could achieve remote code execution on the iSCSI target host.
CVE-2024-41957 1 Vim 1 Vim 2025-11-04 4.5 Medium
Vim is an open source command line text editor. Vim < v9.1.0647 has double free in src/alloc.c:616. When closing a window, the corresponding tagstack data will be cleared and freed. However a bit later, the quickfix list belonging to that window will also be cleared and if that quickfix list points to the same tagstack data, Vim will try to free it again, resulting in a double-free/use-after-free access exception. Impact is low since the user must intentionally execute vim with several non-default flags, but it may cause a crash of Vim. The issue has been fixed as of Vim patch v9.1.0647
CVE-2025-43478 1 Apple 3 Macos, Macos Sequoia, Macos Sonoma 2025-11-04 5.5 Medium

CVE-2022-23608 4 Asterisk, Debian, Sangoma and 1 more 4 Certified Asterisk, Debian Linux, Asterisk and 1 more 2025-11-04 8.1 High
PJSIP is a free and open source multimedia communication library written in C language implementing standard based protocols such as SIP, SDP, RTP, STUN, TURN, and ICE. In versions up to and including 2.11.1 when in a dialog set (or forking) scenario, a hash key shared by multiple UAC dialogs can potentially be prematurely freed when one of the dialogs is destroyed . The issue may cause a dialog set to be registered in the hash table multiple times (with different hash keys) leading to undefined behavior such as dialog list collision which eventually leading to endless loop. A patch is available in commit db3235953baa56d2fb0e276ca510fefca751643f which will be included in the next release. There are no known workarounds for this issue.
CVE-2021-43400 2 Bluez, Debian 2 Bluez, Debian Linux 2025-11-04 9.1 Critical
An issue was discovered in gatt-database.c in BlueZ 5.61. A use-after-free can occur when a client disconnects during D-Bus processing of a WriteValue call.
CVE-2017-9798 3 Apache, Debian, Redhat 8 Http Server, Debian Linux, Enterprise Linux and 5 more 2025-11-04 7.5 High
Apache httpd allows remote attackers to read secret data from process memory if the Limit directive can be set in a user's .htaccess file, or if httpd.conf has certain misconfigurations, aka Optionsbleed. This affects the Apache HTTP Server through 2.2.34 and 2.4.x through 2.4.27. The attacker sends an unauthenticated OPTIONS HTTP request when attempting to read secret data. This is a use-after-free issue and thus secret data is not always sent, and the specific data depends on many factors including configuration. Exploitation with .htaccess can be blocked with a patch to the ap_limit_section function in server/core.c.
CVE-2025-12380 1 Mozilla 1 Firefox 2025-11-04 9.8 Critical
Starting with Firefox 142, it was possible for a compromised child process to trigger a use-after-free in the GPU or browser process using WebGPU-related IPC calls. This may have been usable to escape the child process sandbox. This vulnerability affects Firefox < 144.0.2.
CVE-2025-57109 1 Vtk 1 Vtk 2025-11-04 6.5 Medium

CVE-2024-53140 1 Linux 1 Linux Kernel 2025-11-03 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: netlink: terminate outstanding dump on socket close Netlink supports iterative dumping of data. It provides the families the following ops: - start - (optional) kicks off the dumping process - dump - actual dump helper, keeps getting called until it returns 0 - done - (optional) pairs with .start, can be used for cleanup The whole process is asynchronous and the repeated calls to .dump don't actually happen in a tight loop, but rather are triggered in response to recvmsg() on the socket. This gives the user full control over the dump, but also means that the user can close the socket without getting to the end of the dump. To make sure .start is always paired with .done we check if there is an ongoing dump before freeing the socket, and if so call .done. The complication is that sockets can get freed from BH and .done is allowed to sleep. So we use a workqueue to defer the call, when needed. Unfortunately this does not work correctly. What we defer is not the cleanup but rather releasing a reference on the socket. We have no guarantee that we own the last reference, if someone else holds the socket they may release it in BH and we're back to square one. The whole dance, however, appears to be unnecessary. Only the user can interact with dumps, so we can clean up when socket is closed. And close always happens in process context. Some async code may still access the socket after close, queue notification skbs to it etc. but no dumps can start, end or otherwise make progress. Delete the workqueue and flush the dump state directly from the release handler. Note that further cleanup is possible in -next, for instance we now always call .done before releasing the main module reference, so dump doesn't have to take a reference of its own.
CVE-2024-53103 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2025-11-03 7.8 High
In the Linux kernel, the following vulnerability has been resolved: hv_sock: Initializing vsk->trans to NULL to prevent a dangling pointer When hvs is released, there is a possibility that vsk->trans may not be initialized to NULL, which could lead to a dangling pointer. This issue is resolved by initializing vsk->trans to NULL.
