CVE-2022-50021

CVE-2022-50021 documents a Linux kernel ext4 bug where a validated block range for freeing blocks could be altered after validation on bigalloc filesystems, potentially triggering a kernel BUG in ext4_free_blocks() / ext4_mb_clear_bb(). The issue arises because the range may be adjusted after val...

CVE-2025-38080

The CVE-2025-38080 issue is in the Linux kernel’s AMD display driver (drm/amd/display). The root cause is a buffer overflow in block_sequence when hwss_build_fast_sequence generates more than about 50 steps (e.g., on a 6-pipe ASIC in one MPC chain). The fix expands the block_sequence array to 100...
