21 Oct 2024 — In the Linux kernel, the following vulnerability has been resolved: ACPI: PAD: fix crash in exit_round_robin() The kernel occasionally crashes in cpumask_clear_cpu(), which is called within exit_round_robin(), because when executing clear_bit(nr, addr) with nr set to 0xffffffff, the address calculation may cause misalignment within the memory, leading to access to an invalid memory address. ---------- BUG: unable to handle kernel paging request at ffffffffe0740618 ...
