- btrfs: fix NULL pointer dereference in do_abort_log_replay()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
btrfs: fix NULL pointer dereference in do_abort_log_replay()
Coverity reported a NULL pointer dereference issue (CID 1666756) in do_abort_log_replay(). When btrfs_alloc_path() fails in replay_one_buffer(), wc->subvol_path is NULL, but btrfs_abort_log_replay() calls do_abort_log_replay() which unconditionally dereferences wc->subvol_path when attempting to print debug information. Fix this by adding a NULL check before dereferencing wc->subvol_path in do_abort_log_replay().
