CVE-2022-49409

Summary: CVE-2022-49409 covers a Linux kernel ext4 bug that can trigger a BUG_ON in __es_tree_search due to a faulty check in ext4_valid_extent_entries when validating extents. The issue can occur during quota-related quota inode loading, propagating through ext4/extents.c to ext4_bread, quota_re...

CVE-2022-49408

CVE-2022-49408 involves a memory-leak in ext4 when parsing on-disk mount options in the Linux kernel. The root cause is memory allocated in ext4_fs_context not being freed if option processing fails; the fix replaces direct kfree() with ext4_fc_free(). Practical impact is a leak during mounting w...
