Because BPF tracing programs can be\ninvoked from any interrupt context, locks taken during a map_delete_elem\noperation must be hardirq-safe. Otherwise a deadlock due to lock inversion\nis possible, as reported by lockdep:\n\n CPU0 CPU1\n ---- ----\n lock(&htab->buckets[i].lock);\n local_irq_disable();\n lock(&host->lock);\n lock(&htab->buckets[i].lock);\n \n lock(&host->lock);\n\nLocks in sockmap are hardirq-unsafe by design. We expects elements to be\ndeleted from sockmap/sockhash only in task (normal) context with interrupts\nenabled, or in softirq context.\n\nDetect when map_delete_elem operation is invoked from a context which is\n_not_ hardirq-unsafe, that is interrupts are disabled, and bail out with an\nerror.\n\nNote that map updates are not affected by this issue. BPF verifier does not\nallow updating sockmap/sockhash from a BPF tracing program today.","state":0,"publishedAt":"2024-05-19T08:34:50.276+00:00","modifiedAt":"2026-10-15T00:41:12.685+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 \"net/core/sock_map.c\"\n ],\n \"versions\": [\n {\n \"version\": \"604326b41a6fb9b4a78b6179335decee0365cd8c\",\n \"lessThan\": \"f7990498b05ac41f7d6a190dc0418ef1d21bf058\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"604326b41a6fb9b4a78b6179335decee0365cd8c\",\n \"lessThan\": \"dd54b48db0c822ae7b520bc80751f0a0a173ef75\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"604326b41a6fb9b4a78b6179335decee0365cd8c\",\n \"lessThan\": \"d1e73fb19a4c872d7a399ad3c66e8ca30e0875ec\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"604326b41a6fb9b4a78b6179335decee0365cd8c\",\n \"lessThan\": \"a44770fed86515eedb5a7c00b787f847ebb134a5\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"604326b41a6fb9b4a78b6179335decee0365cd8c\",\n \"lessThan\": \"668b3074aa14829e2ac2759799537a93b60fef86\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"604326b41a6fb9b4a78b6179335decee0365cd8c\",\n \"lessThan\": \"6af057ccdd8e7619960aca1f0428339f213b31cd\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"604326b41a6fb9b4a78b6179335decee0365cd8c\",\n \"lessThan\": \"ff91059932401894e6c86341915615c5eb0eca48\",\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 \"net/core/sock_map.c\"\n ],\n \"versions\": [\n {\n \"version\": \"4.20\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"4.20\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.4.274\",\n \"lessThanOrEqual\": \"5.4.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.10.215\",\n \"lessThanOrEqual\": \"5.10.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.154\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.85\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.26\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.8.5\",\n \"lessThanOrEqual\": \"6.8.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.9\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/f7990498b05ac41f7d6a190dc0418ef1d21bf058","https://git.kernel.org/stable/c/dd54b48db0c822ae7b520bc80751f0a0a173ef75","https://git.kernel.org/stable/c/d1e73fb19a4c872d7a399ad3c66e8ca30e0875ec","https://git.kernel.org/stable/c/a44770fed86515eedb5a7c00b787f847ebb134a5","https://git.kernel.org/stable/c/668b3074aa14829e2ac2759799537a93b60fef86","https://git.kernel.org/stable/c/6af057ccdd8e7619960aca1f0428339f213b31cd","https://git.kernel.org/stable/c/ff91059932401894e6c86341915615c5eb0eca48"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2024-35895","license":"CVE Program Terms of Use","key":"cve-program:CVE-2024-35895","identifiers":["CVE-2024-35895"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
