  "description": "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-\u003Esubvol_path is NULL, but btrfs_abort_log_replay() calls do_abort_log_replay() which unconditionally dereferences wc-\u003Esubvol_path when attempting to print debug information. Fix this by adding a NULL check before dereferencing wc-\u003Esubvol_path in do_abort_log_replay().",
