If pool creation\nfails, probe still continues with DMA setup, algorithm registration and\nchild population even though later request setup depends on that pool.\n\nStop probing when sa_init_mem() fails, and route that failure to the PM\ncleanup path without attempting to destroy an uncreated DMA pool.","state":0,"publishedAt":"2026-09-17T16:11:53.144+00:00","modifiedAt":"2026-10-19T09:06:30.18+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/crypto/sa2ul.c\"\n ],\n \"versions\": [\n {\n \"version\": \"7694b6ca649fead1a57046935711bc82dfc78cfb\",\n \"lessThan\": \"304dcd26bfc3ce6771c2bd3b7c0299dcfd5f4e06\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"7694b6ca649fead1a57046935711bc82dfc78cfb\",\n \"lessThan\": \"9907426b438e4dbc8c45138bd440ad6d732d80b7\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"7694b6ca649fead1a57046935711bc82dfc78cfb\",\n \"lessThan\": \"9a692a6a2b47328a36c8d80c7fbf81da16b6d6b1\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"7694b6ca649fead1a57046935711bc82dfc78cfb\",\n \"lessThan\": \"04c46784ec249cac995e31f0691397b82bdaa5fd\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"7694b6ca649fead1a57046935711bc82dfc78cfb\",\n \"lessThan\": \"f72c7837614a9705f8b3021828d49c9f095803ba\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"7694b6ca649fead1a57046935711bc82dfc78cfb\",\n \"lessThan\": \"91ded4742fcde6ad415c4d8a20e5ea0dcdf4f73e\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"7694b6ca649fead1a57046935711bc82dfc78cfb\",\n \"lessThan\": \"b68b35ed97d3e18edb9dea500d88420a95006742\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"7694b6ca649fead1a57046935711bc82dfc78cfb\",\n \"lessThan\": \"d03f980a25853f6a380895119a572a3bb1194e8d\",\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/crypto/sa2ul.c\"\n ],\n \"versions\": [\n {\n \"version\": \"5.9\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"5.9\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.10.270\",\n \"lessThanOrEqual\": \"5.10.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.221\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.188\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.157\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.110\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.52\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.2.6\",\n \"lessThanOrEqual\": \"7.2.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.3\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/304dcd26bfc3ce6771c2bd3b7c0299dcfd5f4e06","https://git.kernel.org/stable/c/9907426b438e4dbc8c45138bd440ad6d732d80b7","https://git.kernel.org/stable/c/9a692a6a2b47328a36c8d80c7fbf81da16b6d6b1","https://git.kernel.org/stable/c/04c46784ec249cac995e31f0691397b82bdaa5fd","https://git.kernel.org/stable/c/f72c7837614a9705f8b3021828d49c9f095803ba","https://git.kernel.org/stable/c/91ded4742fcde6ad415c4d8a20e5ea0dcdf4f73e","https://git.kernel.org/stable/c/b68b35ed97d3e18edb9dea500d88420a95006742","https://git.kernel.org/stable/c/d03f980a25853f6a380895119a572a3bb1194e8d"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93158","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93158","identifiers":["CVE-2026-93158"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
