CVE-2026-64560

CVE-2026-64560 documents a Linux kernel issue in posix-cpu-timers that can cause a Use-After-Free when a timer is deleted during a non-leader exec() race. The vulnerability arises as sys_timer_delete() may observe an old leader while a leader change occurs, leading to a freed posix timer object b...

CVE-2026-64380

A flaw was found in the Linux kernel's Server Message Block SMB client. The vulnerability exists in the posixinfosidsize function, which is responsible for parsing POSIX Security Identifiers SIDs. An insufficient boundary check allows the system to accept truncated POSIX SIDs, which could lead to...

CVE-2026-64287

A flaw was found in the Kernel-based Virtual Machine KVM component of the Linux kernel on ARM64 systems. A highly privileged local attacker could exploit a vulnerability where the system fails to properly restrict memory access during a specific virtual machine operation. This could allow the...
