Not only is that\na very bad idea, it has also never worked because gfs2_recover_func()\nwill refuse to do anything during a withdraw.\n\nHowever, before even getting to this point, gfs2_recover_func()\ndereferences sdp->sd_jdesc->jd_inode. This was a use-after-free before\ncommit 04133b607a78 (\"gfs2: Prevent double iput for journal on error\")\nand is a NULL pointer dereference since then.\n\nSimply get rid of self recovery to fix that.","state":0,"publishedAt":"2025-08-22T16:01:02.448+00:00","modifiedAt":"2026-10-15T22:02:27.671+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"unaffected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"fs/gfs2/util.c\"\n ],\n \"versions\": [\n {\n \"version\": \"601ef0d52e9617588fcff3df26953592f2eb44ac\",\n \"lessThan\": \"69cf5699a402ee7ae1be53954dc2ae652c0a053c\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"601ef0d52e9617588fcff3df26953592f2eb44ac\",\n \"lessThan\": \"6ebe17b359bead383581f729e43f591c1c36e159\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"601ef0d52e9617588fcff3df26953592f2eb44ac\",\n \"lessThan\": \"1a91ba12abef628b43cada87478328274d988e88\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"601ef0d52e9617588fcff3df26953592f2eb44ac\",\n \"lessThan\": \"f5426ffbec971a8f7346a57392d3a901bdee5a9b\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"601ef0d52e9617588fcff3df26953592f2eb44ac\",\n \"lessThan\": \"6784367b2f3cd7b89103de35764f37f152590dbd\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"601ef0d52e9617588fcff3df26953592f2eb44ac\",\n \"lessThan\": \"97c94c7dbddc34d353c83b541b3decabf98d04af\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"601ef0d52e9617588fcff3df26953592f2eb44ac\",\n \"lessThan\": \"deb016c1669002e48c431d6fd32ea1c20ef41756\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n }\n ]\n }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n \"product\": \"Linux\",\n \"vendor\": \"Linux\",\n \"defaultStatus\": \"affected\",\n \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n \"programFiles\": [\n \"fs/gfs2/util.c\"\n ],\n \"versions\": [\n {\n \"version\": \"5.7\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"5.7\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.209\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.167\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.102\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.42\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.15.10\",\n \"lessThanOrEqual\": \"6.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.16.1\",\n \"lessThanOrEqual\": \"6.16.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.17\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/69cf5699a402ee7ae1be53954dc2ae652c0a053c","https://git.kernel.org/stable/c/6ebe17b359bead383581f729e43f591c1c36e159","https://git.kernel.org/stable/c/1a91ba12abef628b43cada87478328274d988e88","https://git.kernel.org/stable/c/f5426ffbec971a8f7346a57392d3a901bdee5a9b","https://git.kernel.org/stable/c/6784367b2f3cd7b89103de35764f37f152590dbd","https://git.kernel.org/stable/c/97c94c7dbddc34d353c83b541b3decabf98d04af","https://git.kernel.org/stable/c/deb016c1669002e48c431d6fd32ea1c20ef41756"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-38659","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-38659","identifiers":["CVE-2025-38659"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
