CVE-2022-50306

CVE-2022-50306 concerns a Linux kernel issue in ext4 where ext4_fc_replay_scan() could perform an out-of-bounds read during journal scan if the remaining space is smaller than EXT4_FC_TAG_BASE_LEN. The root cause is insufficient bounds checking for the three journal scan tags (ADD_RANGE/HEAD/TAIL...
