And indeed\nit will, some 0.4% of times this code is called.\n\nThen enqueue + 1 is an invalid pointer. It will crash the kernel right\naway or load some junk which may look like a link TRB and cause the real\nlink TRB to be replaced with a NOOP. This wouldn't end well.\n\nUse a functionally equivalent test which doesn't dereference the pointer\nand always gives correct result.\n\nSomething has crashed my machine twice in recent days while playing with\nan Etron HC, and a control transfer stress test ran for confirmation has\njust crashed it again. The same test passes with this patch applied.","state":0,"publishedAt":"2025-05-08T06:26:10+00:00","modifiedAt":"2026-10-15T21:52:00.5+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/usb/host/xhci-ring.c\"\n ],\n \"versions\": [\n {\n \"version\": \"fbc0a0c7718a6cb1dc5e0811a4f88a2b1deedfa1\",\n \"lessThan\": \"142273a49f2c315eabdbdf5a71c15e479b75ca91\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"9258c9ed32294ce3a4b58c9d92fc49ba030d35c9\",\n \"lessThan\": \"bce3055b08e303e28a8751f6073066f5c33a0744\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"5e1c67abc9301d05130b7e267c204e7005503b33\",\n \"lessThan\": \"0624e29c595b05e7a0e6d1c368f0a05799928e30\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"5e1c67abc9301d05130b7e267c204e7005503b33\",\n \"lessThan\": \"1ea050da5562af9b930d17cbbe9632d30f5df43a\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"4725344ca645a98a9d8e45e25b01a2244de5b8aa\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"6.6.66\",\n \"lessThan\": \"6.6.89\",\n \"status\": \"affected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.2\",\n \"lessThan\": \"6.12.26\",\n \"status\": \"affected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.11.11\",\n \"lessThan\": \"6.12\",\n \"status\": \"affected\",\n \"versionType\": \"semver\"\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/usb/host/xhci-ring.c\"\n ],\n \"versions\": [\n {\n \"version\": \"6.13\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"6.13\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.89\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.26\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.14.5\",\n \"lessThanOrEqual\": \"6.14.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.15\",\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/142273a49f2c315eabdbdf5a71c15e479b75ca91","https://git.kernel.org/stable/c/bce3055b08e303e28a8751f6073066f5c33a0744","https://git.kernel.org/stable/c/0624e29c595b05e7a0e6d1c368f0a05799928e30","https://git.kernel.org/stable/c/1ea050da5562af9b930d17cbbe9632d30f5df43a"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-37813","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-37813","identifiers":["CVE-2025-37813"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
