kernel: Linux kernel: Denial of Service due to NULL function pointer race in timer shutdown

A flaw was found in the Linux kernel. A race condition exists in the timershutdownsync function, where a timer's function pointer can be set to NULL while the timer is still active on another processor. This can be exploited by a local attacker to trigger a kernel warning, potentially leading to...

CVE-2026-64560

A flaw was found in the Linux kernel's CPU timer functionality. A race condition, which is a timing issue between different operations, can occur when a process attempts to delete a timer while another operation is still trying to access it. This can lead to a Use-After-Free UAF vulnerability,...

CVE-2026-64370

A flaw was found in the Linux kernel's posix-cpu-timers component. This vulnerability allows a local user to trigger a resource leak within the docpunanosleep function. The issue occurs because a process identifier PID reference is not properly released if a timer creation operation fails. This...
