kernel: net: sched: UAF via missing handler for TC_ACT_CONSUMED in tcf_qevent_handle
A flaw was found in the Linux kernel's traffic control TC classifier application programming interface API. The tcfqeventhandle function does not properly handle a consumed socket buffer skb when it is processed by the defragmentation engine. This can lead to a Use-After-Free UAF vulnerability,...

An update for kernel is now available for Red Hat Enterprise Linux 9. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for each vulnerability from th...
kernel: tipc: fix double-free in tipc_buf_append()
A flaw was found in the Linux kernel's Transparent Inter-Process Communication TIPC module. This vulnerability, a double-free, occurs when the tipcbufappend function incorrectly handles memory after a socket buffer skb reallocation. An attacker could potentially exploit this to cause system...
kernel: ipc: limit next_id allocation to the valid ID range
A flaw was found in the Linux kernel. The ipcidralloc function, used in the checkpoint/restore path for SysV Inter-Process Communication IPC ID allocation, does not properly limit ID allocation to the valid range. This can result in the system attempting to dereference freed memory, leading to a...

JLSEC-2026-1085 libssh2 through 1.11.1, fixed in commit 5e47761, contains a double-free vulnerability in the...
libssh2 through 1.11.1, fixed in commit 5e47761, contains a double-free vulnerability in the sftpopen function in src/sftp.c that allows a malicious SSH server to corrupt the heap of any authenticated client opening an SFTP session. When a server responds to SSHFXPOPEN with SSHFXPSTATUS containin...
CVE-2026-63729
A flaw was found in the SyncTeX parser, part of TeX Live and used by applications like GNOME Evince. A remote attacker could exploit a heap use-after-free vulnerability by providing a specially crafted SyncTeX file e.g., .synctex or .synctex.gz. This could lead to application crashes or, in sever...
SUSE CVE-2026-12996
A use-after-free in OpenVPN 2.6.0 through 2.6.20 and 2.7alpha1 through 2.7.4 allows remote authenticated peers to potentially cause a denial of service or leak memory via crafted packets during TLS session promotion or expiry...
SUSE CVE-2026-13117
An incomplete guard in OpenVPN 2.6.0 through 2.6.20 and 2.7alpha1 through 2.7.4 allows remote authenticated peers to trigger a use-after-free during TLS session promotion, potentially leading to a denial of service or memory leakage...

CVE-2026-10685
The Zephyr Bluetooth GATT client CCC-write response handler gattwritecccrsp in subsys/bluetooth/host/gatt.c invoked the application's params-subscribe callback after it had already called params-notifyconn, params, NULL, 0. Per the public GATT API, a notify callback with NULL data is the document...
CVE-2026-63035
A flaw was found in open62541. This vulnerability, known as a use-after-free, occurs in the TransferSubscriptions service when memory is improperly managed after it has been released. An authenticated attacker could exploit this flaw to trigger a denial of service, making the system unresponsive,...
