{"id":"CVE-2026-72362","summary":"drm/xe/pt: Fix NULL pointer dereference in xe_pt_zap_ptes_entry()","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ndrm/xe/pt: Fix NULL pointer dereference in xe_pt_zap_ptes_entry()\n\nThe page-table walk framework may pass a NULL *child pointer for\nunpopulated entries. xe_pt_zap_ptes_entry() called container_of(*child)\nbefore checking for NULL, then dereferenced the result, causing a crash.\n\nMove the container_of() call after a NULL guard, so the function returns\nearly instead of proceeding with an invalid pointer. XE_WARN_ON is kept\nto help root cause the issue, but we now bail instead of crashing the\ndriver.\n\nv2: Comment that triggering XE_WARN_ON is unexpected behavior (Matt Brost)\n\n(cherry picked from commit b9297d19d9df5d4b6c994648570c5dcd1cac68ff)","modified":"2026-08-16T03:48:37.388816721Z","published":"2026-08-15T05:56:01.414Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72362.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/3feeb667197bd58a17f4edfdbcad249ffcb3c864"},{"type":"WEB","url":"https://git.kernel.org/stable/c/78b1074966d290d4517f42bc81e13c4349368d12"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d94b9922b2ae5ee6e900f8da0bd537b251c6110c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/ff330ce16c846b70164ff0eb544c81219d4c5c08"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72362.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72362"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"dd08ebf6c3525a7ea2186e636df064ea47281987"},{"fixed":"ff330ce16c846b70164ff0eb544c81219d4c5c08"},{"fixed":"78b1074966d290d4517f42bc81e13c4349368d12"},{"fixed":"d94b9922b2ae5ee6e900f8da0bd537b251c6110c"},{"fixed":"3feeb667197bd58a17f4edfdbcad249ffcb3c864"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72362.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"6.8.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72362.json"}}],"schema_version":"1.9.0"}
