FreeBSD -- Use-after-free in TCP RACK stack option handler

Problem Description: The RACK setsockopt2 handler drops the connection lock in order to copy option data from userspace, then reacquires the lock. After reacquiring, it verifies that the TCP stack had not been switched away, but did not reload its pointer to the stack's per-connection control...

cifs-utils: local privilege escalation via forged cifs.spnego key description in cifs.upcall

A flaw was found in the cifs-utils package where the cifs.upcall helper fails to securely drop its root privileges before looking up user information inside a user-controlled environment. A local, low privileged attacker can exploit this by using a crafted requestkey payload to trick the root-own...

CVE-2026-53323

A flaw was found in the Linux kernel's Distributed Switch Architecture DSA subsystem. Redundant locking operations within the DSA conduit ethtool wrappers can lead to a deadlock. A local attacker can exploit this by using the ethtool -i command, causing the system to become unresponsive and...
