CVE-2022-49007

CVE-2022-49007 affects the Linux kernel/NILFS2. A NULL pointer dereference in nilfs_palloc_commit_free_entry() could occur during DAT metadata handling when a lower-level DAT block’s entry is clobbered during commit, leading to a crash. The fix adds NULL checks in nilfs_dat_commit_free() for req-...
