2024-02-27 CVE-2020-36776 Improper Validation of Array Index vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: thermal/drivers/cpufreq_cooling: Fix slab OOB issue Slab OOB issue is scanned by KASAN in cpu_power_to_freq(). If power is limited below the power of OPP0 in EM table, it will cause slab out-of-bound issue with negative array index. Return the lowest frequency if limited power cannot found a suitable OPP in EM table to fix this issue.

2024-02-27 CVE-2021-46950 Unspecified vulnerability in Linux Kernel
In the Linux kernel, the following vulnerability has been resolved: md/raid1: properly indicate failure when ending a failed write request This patch addresses a data corruption bug in raid1 arrays using bitmaps. Without this fix, the bitmap bits for the failed I/O end up being cleared. Since we are in the failure leg of raid1_end_write_request, the request either needs to be retried (R1BIO_WriteError) or failed (R1BIO_Degraded).
