This patch addresses CVE-2024-49935 [1], a vulnerability in ACPI subsystem caused by calling cpumask_clear_cpu() with bit to clear set to 0xffffffff, thus leading to erroneous memory access. The issue is still present in 5.10.y kernel. The original commit [2] has been backported to several stable branches (5.15.y and fresher) and now has been cherry-picked for 5.10.y.
