  "description": "In the Linux kernel, the following vulnerability has been resolved:  ocfs2: fix UBSAN array-index-out-of-bounds in ocfs2_sum_rightmost_rec  [BUG] On-disk corruption setting l_next_free_rec to 0 in an inode\u0027s embedded extent list triggers a UBSAN panic on the next write to that file.  [CAUSE] ocfs2_sum_rightmost_rec() computes i = le16_to_cpu(el-\u003El_next_free_rec) - 1 and accesses el-\u003El_recs[i] without validating i. When l_next_free_rec is 0, i becomes -1; when l_next_free_rec exceeds l_count, i falls past the end of the array. Either case violates the __counted_by_le(l_count) annotation on l_recs[] and triggers UBSAN.  [FIX] Validate the inode\u0027s embedded extent list when the inode is read, in ocfs2_validate_inode_block(): l_count must be non-zero and no larger than the inode block can hold, and l_next_free_rec must not exceed l_count. A corrupt list is rejected at read time, before the b-tree code can index l_recs[] out of bounds.",
