Later, when VFS evicts remaining cached inodes,\nocfs2_evict_inode() -> ocfs2_clear_inode() -> ocfs2_checkpoint_inode()\n-> ocfs2_ci_fully_checkpointed() dereferences osb->journal, causing a\nNULL pointer dereference.\n\nFix this by adding a NULL check for osb->journal in\nocfs2_checkpoint_inode(). If the journal is NULL, it has already been\nfully flushed and destroyed during shutdown, so there is nothing to\ncheckpoint.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/24daf13422e8328fd588c34a017bdef1949910e8","https://git.kernel.org/stable/c/499714de42ab4d2e778cbb10186684142a1222eb","https://git.kernel.org/stable/c/63921f790234b221e4b15c56c72888b13250f81d","https://git.kernel.org/stable/c/7da7e4ac21895fe34cceffcfc99497cc2750da99","https://git.kernel.org/stable/c/a291c77c034b7a81849ce9b71cc9ecda9e587d89"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:48:17.459049833+00:00"},"epss":{"cve":"CVE-2026-72161","score":0.00211,"percentile":0.11402,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
