This triggers an alignment fault (FSC=0x21) Oops in\nath10k_snoc_fw_crashed_dump() while collecting the devcoredump:\n\n Unable to handle kernel paging request ... FSC=0x21: alignment fault\n pc : __pi_memcpy_generic\n lr : ath10k_snoc_fw_crashed_dump [ath10k_snoc]\n\nThe Oops both leaves the firmware RAM dump buffer zeroed (no dump is\ncaptured) and crashes the kernel, which in turn breaks modem SSR\nrecovery.\n\nUse memcpy_fromio(), which only performs accesses that are valid for such\na device-memory mapping. The generic memcpy_fromio() implementation aligns\nthe source before issuing word-sized reads and stores the destination with\nput_unaligned(), so it is also safe for the coherent DMA allocation used on\nthe non-reserved-memory path. ath11k and ath12k use the same pattern\nwhen copying target memory into crash dumps, so call it unconditionally\nhere too.\nThe MEMREMAP_WT pointer is a plain void *, so an explicit __iomem cast is\nneeded; use __force to keep sparse happy.\n\nTested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.3.7.c5-00107-QCAHLSWMTPL-1","state":0,"publishedAt":"2026-09-17T16:08:56.885+00:00","modifiedAt":"2026-10-19T09:02:05.059+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/net/wireless/ath/ath10k/snoc.c\"\n ],\n \"versions\": [\n {\n \"version\": \"3f14b73c38431a6a1ed24de568e18ed89b7082e2\",\n \"lessThan\": \"e5bc3658da9c8a535e3fa5c0c875b2a456954e81\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"3f14b73c38431a6a1ed24de568e18ed89b7082e2\",\n \"lessThan\": \"fed1f662c9f9fd19eeab6c01966b7b5a33804420\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"3f14b73c38431a6a1ed24de568e18ed89b7082e2\",\n \"lessThan\": \"838cab267ce9a975776e022f25094f8cbe1625d2\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"3f14b73c38431a6a1ed24de568e18ed89b7082e2\",\n \"lessThan\": \"eb946595a58decdb4cab1b5f3c972ae66f41f1c8\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"3f14b73c38431a6a1ed24de568e18ed89b7082e2\",\n \"lessThan\": \"152e894e90716163c646d70f86b3afeb70442783\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"3f14b73c38431a6a1ed24de568e18ed89b7082e2\",\n \"lessThan\": \"7039825a7479df637c4f5d546cb0e1cec18cd8e1\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"3f14b73c38431a6a1ed24de568e18ed89b7082e2\",\n \"lessThan\": \"045d1bfb72d2631ab9ec74afa491aa788ebb57aa\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"3f14b73c38431a6a1ed24de568e18ed89b7082e2\",\n \"lessThan\": \"4f25071afe9218aaae1c63fbf75e229aa6405319\",\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/net/wireless/ath/ath10k/snoc.c\"\n ],\n \"versions\": [\n {\n \"version\": \"5.5\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"5.5\",\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/e5bc3658da9c8a535e3fa5c0c875b2a456954e81","https://git.kernel.org/stable/c/fed1f662c9f9fd19eeab6c01966b7b5a33804420","https://git.kernel.org/stable/c/838cab267ce9a975776e022f25094f8cbe1625d2","https://git.kernel.org/stable/c/eb946595a58decdb4cab1b5f3c972ae66f41f1c8","https://git.kernel.org/stable/c/152e894e90716163c646d70f86b3afeb70442783","https://git.kernel.org/stable/c/7039825a7479df637c4f5d546cb0e1cec18cd8e1","https://git.kernel.org/stable/c/045d1bfb72d2631ab9ec74afa491aa788ebb57aa","https://git.kernel.org/stable/c/4f25071afe9218aaae1c63fbf75e229aa6405319"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-90348","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-90348","identifiers":["CVE-2026-90348"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog;
