GHSA-7RQ4-PC5W-9JQ7
Vulnerability from github – Published: 2025-07-10 09:32 – Updated: 2025-11-20 18:31In the Linux kernel, the following vulnerability has been resolved:
btrfs: exit after state insertion failure at btrfs_convert_extent_bit()
If insert_state() state failed it returns an error pointer and we call extent_io_tree_panic() which will trigger a BUG() call. However if CONFIG_BUG is disabled, which is an uncommon and exotic scenario, then we fallthrough and call cache_state() which will dereference the error pointer, resulting in an invalid memory access.
So jump to the 'out' label after calling extent_io_tree_panic(), it also makes the code more clear besides dealing with the exotic scenario where CONFIG_BUG is disabled.
