CVE-2026-98260

The Linux kernel is vulnerable to a use-after-free condition during the execve() system call. The issue occurs when a non-leader thread executes; while de_thread() changes the PID ownership, a per-thread CPU timer node remains queued on the original thread's posix_cputimers. If subsequent operati...

CVE-2026-98259

The Linux kernel is vulnerable to a kernel panic when booting a VM with DAX enabled storage . The issue is caused by calling dax_to_folio() with an empty entry , which occurs in the fs/dax component. Specifically, the vulnerability persists in dax_associate_entry(), dax_disassociate_entry(), and ...

CVE-2026-98258

A race condition exists in the Linux kernel within the posix-cpu-timers component. The issue stems from a previous commit that converted cpu_timer::firing from a tristate value to a boolean, causing a loss of distinction between timers not owned by the firing list and those where delivery was can...

CVE-2026-98256

A use-after-free (UAF) vulnerability exists in the Linux kernel signal handling logic. The issue occurs during a non-leader exec() call where a SIGEV_THREAD_ID timer's struct pid points to a thread that has already called execve(). Due to a non-atomic list_del_init() operation, a signal queue ent...
