CVE-2022-50221

CVE-2022-50221 : In the Linux kernel, the drm/fb-helper deferred I/O damage handling could compute an clipping range that allowed an out-of-bounds access when the fbdev screen buffer ended near the start of a page. The patch clamps the maximum memory range to the screen buffer size and also renam...

CVE-2022-50066

Summary: CVE-2022-50066 affects the Linux kernel’s net/atlantic driver (Aquantia) where the final iteration of a for loop can dereference an out-of-bounds aq_vec entry, causing a UBSAN array-index-out-of-bounds condition. The issue manifests as index 8 being out of range for aq_vec_s *[8] in aq_n...

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-2022-49985

The CVE-2022-49985 entry concerns the Linux kernel, where the BPF component allowed a range check descriptor to misrepresent a tight range because tnum_range(0, map->max_entries-1) may yield a superset of the intended values. The root cause is that the tnum-based range representation can erron...
