CVE-2024-35936
"Btrfs Kernel Chunk Tree Item Offset Validation Vulnerability"
Description
In the Linux kernel, the following vulnerability has been resolved: btrfs: handle chunk tree lookup error in btrfs_relocate_sys_chunks() The unhandled case in btrfs_relocate_sys_chunks() loop is a corruption, as it could be caused only by two impossible conditions: - at first the search key is set up to look for a chunk tree item, with offset -1, this is an inexact search and the key->offset will contain the correct offset upon a successful search, a valid chunk tree item cannot have an offset -1 - after first successful search, the found_key corresponds to a chunk item, the offset is decremented by 1 before the next loop, it's impossible to find a chunk item there due to alignment and size constraints
