CVE-2024-49935: ACPI: PAD: fix crash in exit_round_robin()

Published Oct 21, 2024

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 clearbit(nr, addr) with nr set to 0xffffffff, the address calculation may cause misalignment within the memory, leading to access to an invalid memory address.

To fix this, ensure that tskincpu[tskindex] != -1 before calling cpumaskclearcpu() in exitroundrobin(), just as it is done in roundrobincpu().
