{"apiVersion":"1.0","identifier":"CVE-2026-72161","description":"In the Linux kernel, the following vulnerability has been resolved: ocfs2: add journal NULL check in ocfs2_checkpoint_inode() During unmount, ocfs2_journal_shutdown() frees the journal and sets osb->journal to NULL. Later, when VFS evicts remaining cached inodes, ocfs2_evict_inode() -> ocfs2_clear_inode() -> ocfs2_checkpoint_inode() -> ocfs2_ci_fully_checkpointed() dereferences osb->journal, causing a NULL pointer dereference. Fix this by adding a NULL check for osb->journal in ocfs2_checkpoint_inode(). If the journal is NULL, it has already been fully flushed and destroyed during shutdown, so there is nothing to checkpoint.","publishedAt":"2026-08-15T06:21:33","lastModifiedAt":"2026-08-17T06:18:16","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72161","cvssScore":null,"cvssVector":"Pending","epssProbability":0.00206,"riskScore":0,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72161","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72161","en":"https://www.redsauce.net/en/cves/CVE-2026-72161","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72161","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72161","de":"https://www.redsauce.net/de/cves/CVE-2026-72161","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72161","el":"https://www.redsauce.net/el/cves/CVE-2026-72161"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72161"}}
