Since this\ncan happen asynchronously from the normal behavior of the\ndriver, the cleanup may happen when holding other locks\nin the calling sequence (notably, the cio subchannel lock).\n\nPush the cleanup of the private->cp resources to a workqueue,\nwhere it can be done out from under that lock sequence and\na future patch can safely manage the locking requirements.","state":0,"publishedAt":"2026-08-26T14:37:19.353+00:00","modifiedAt":"2026-10-16T19:26:25.99+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 \"drivers/s390/cio/vfio_ccw_drv.c\",\n \"drivers/s390/cio/vfio_ccw_fsm.c\",\n \"drivers/s390/cio/vfio_ccw_ops.c\",\n \"drivers/s390/cio/vfio_ccw_private.h\"\n ],\n \"versions\": [\n {\n \"version\": \"204b394a23ad5e30944f23518e21e844614da2ff\",\n \"lessThan\": \"c9b85aa2cf73ea645e55e2c2670e0ddebfe1589b\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"204b394a23ad5e30944f23518e21e844614da2ff\",\n \"lessThan\": \"f98a9890ca42f4223d2d4c50e0660af3e012fcb4\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"204b394a23ad5e30944f23518e21e844614da2ff\",\n \"lessThan\": \"4e3301e2a651d742c05914f6074a25b8e41bce19\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"204b394a23ad5e30944f23518e21e844614da2ff\",\n \"lessThan\": \"af1759d8e6e6da9ba94f30a2f92546f406899aa7\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"204b394a23ad5e30944f23518e21e844614da2ff\",\n \"lessThan\": \"56100baa0eb7055b1026dfa73e696e8066ff71fd\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"204b394a23ad5e30944f23518e21e844614da2ff\",\n \"lessThan\": \"0c11f61a876ed6fcca53d442ed3f33ea8362a0f9\",\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 \"drivers/s390/cio/vfio_ccw_drv.c\",\n \"drivers/s390/cio/vfio_ccw_fsm.c\",\n \"drivers/s390/cio/vfio_ccw_ops.c\",\n \"drivers/s390/cio/vfio_ccw_private.h\"\n ],\n \"versions\": [\n {\n \"version\": \"6.0\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"6.0\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.185\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.153\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.105\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.46\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.1.10\",\n \"lessThanOrEqual\": \"7.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.2\",\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:H/UI:N/S:C/C:H/I:H/A:H","score":8.2,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/c9b85aa2cf73ea645e55e2c2670e0ddebfe1589b","https://git.kernel.org/stable/c/f98a9890ca42f4223d2d4c50e0660af3e012fcb4","https://git.kernel.org/stable/c/4e3301e2a651d742c05914f6074a25b8e41bce19","https://git.kernel.org/stable/c/af1759d8e6e6da9ba94f30a2f92546f406899aa7","https://git.kernel.org/stable/c/56100baa0eb7055b1026dfa73e696e8066ff71fd","https://git.kernel.org/stable/c/0c11f61a876ed6fcca53d442ed3f33ea8362a0f9"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-80549","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-80549","identifiers":["CVE-2026-80549"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
