CVE-2024-49935

In the Linux kernel, the following vulnerability has been resolved: ACPI: PAD: fix crash in exitroundrobin The kernel occasionally crashes in cpumaskclearcpu, which is called within exitroundrobin, because when executing clearbitnr, addr with nr set to 0xffffffff, the address calculation may caus...

CVE-2024-49935

CVE-2024-49935 involves the Linux kernel ACPI PAD path (exit_round_robin) where a crash can occur in cpumask_clear_cpu() due to clear_bit(nr) with nr = 0xffffffff and misaligned memory access. The fixed issue, as documented, is to validate tsk_in_cpu[tsk_index] != -1 before calling cpumask_clear_...
