CVE-2024-35936

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> btrfs: handle chunk tree lookup error in btrfs_relocate_sys_chunks()<br /> <br /> The unhandled case in btrfs_relocate_sys_chunks() loop is a corruption,<br /> as it could be caused only by two impossible conditions:<br /> <br /> - at first the search key is set up to look for a chunk tree item, with<br /> offset -1, this is an inexact search and the key-&gt;offset will contain<br /> the correct offset upon a successful search, a valid chunk tree item<br /> cannot have an offset -1<br /> <br /> - after first successful search, the found_key corresponds to a chunk<br /> item, the offset is decremented by 1 before the next loop, it&amp;#39;s<br /> impossible to find a chunk item there due to alignment and size<br /> constraints
