Some\nstring fields are not NUL-terminated. One example is the dynamic char\narray of the xfs_* namespace tracepoints, which is copied without a\ntrailing NUL. For such a field, glob matching reads past the end of\nthe event field, causing a KASAN slab-out-of-bounds read in\nglob_match(), reached via regex_match_glob() and filter_match_preds()\nfrom the xfs_lookup tracepoint.\n\nAdd a length-bounded glob_match_len() and use it from regex_match_glob()\nso glob matching always stops at the field boundary. The matching loop\nis factored into a shared helper so glob_match() keeps its behaviour.","state":0,"publishedAt":"2026-07-25T08:49:35.742+00:00","modifiedAt":"2026-10-19T20:38:22.703+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 \"include/linux/glob.h\",\n \"kernel/trace/trace_events_filter.c\",\n \"lib/glob.c\"\n ],\n \"versions\": [\n {\n \"version\": \"60f1d5e3bac44b598f67d36062da96c095d2b700\",\n \"lessThan\": \"265f3a690f6c7d69ef7d2ca50b04b4853a211df3\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"60f1d5e3bac44b598f67d36062da96c095d2b700\",\n \"lessThan\": \"ee5b8888d3248618251fb69a2fad92afcb81557e\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"60f1d5e3bac44b598f67d36062da96c095d2b700\",\n \"lessThan\": \"56d4c9ab84714eebb285a2fee68aaedf81e3ef15\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"60f1d5e3bac44b598f67d36062da96c095d2b700\",\n \"lessThan\": \"35ae19764eabfe9c29029d3b5713c86e6855acdf\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"60f1d5e3bac44b598f67d36062da96c095d2b700\",\n \"lessThan\": \"ebb55902856973906c8bb339a3a34824ed4a5086\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"60f1d5e3bac44b598f67d36062da96c095d2b700\",\n \"lessThan\": \"2dad64a97e1df47f5d9ccb17fa319aa348617226\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"60f1d5e3bac44b598f67d36062da96c095d2b700\",\n \"lessThan\": \"e5d5f3bd053a5f14787526c9f0f55ef900d43ac6\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"60f1d5e3bac44b598f67d36062da96c095d2b700\",\n \"lessThan\": \"0a6070839b1ef276d5b05bedfb787743e140fb17\",\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 \"include/linux/glob.h\",\n \"kernel/trace/trace_events_filter.c\",\n \"lib/glob.c\"\n ],\n \"versions\": [\n {\n \"version\": \"4.10\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"4.10\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.10.261\",\n \"lessThanOrEqual\": \"5.10.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.212\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.178\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.145\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.96\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.39\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.1.4\",\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:L/UI:N/S:U/C:H/I:N/A:H","score":7.1,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/265f3a690f6c7d69ef7d2ca50b04b4853a211df3","https://git.kernel.org/stable/c/ee5b8888d3248618251fb69a2fad92afcb81557e","https://git.kernel.org/stable/c/56d4c9ab84714eebb285a2fee68aaedf81e3ef15","https://git.kernel.org/stable/c/35ae19764eabfe9c29029d3b5713c86e6855acdf","https://git.kernel.org/stable/c/ebb55902856973906c8bb339a3a34824ed4a5086","https://git.kernel.org/stable/c/2dad64a97e1df47f5d9ccb17fa319aa348617226","https://git.kernel.org/stable/c/e5d5f3bd053a5f14787526c9f0f55ef900d43ac6","https://git.kernel.org/stable/c/0a6070839b1ef276d5b05bedfb787743e140fb17"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-64299","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-64299","identifiers":["CVE-2026-64299"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
