The function directly assigns NULL to gchan->config, losing the\n reference to the original memory\n4. The original memory becomes unreachable and cannot be freed\n\nFix this by using a temporary variable to hold the krealloc() result\nand only updating gchan->config when the allocation succeeds.\n\nFound via static analysis and code review.","state":0,"publishedAt":"2026-01-31T11:42:05.185+00:00","modifiedAt":"2026-10-15T01:12:41.525+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/dma/qcom/gpi.c\"\n ],\n \"versions\": [\n {\n \"version\": \"5d0c3533a19f48e5e7e73806a3e4b29cd4364130\",\n \"lessThan\": \"4532f18e4ab36def1f55cd936d0fc002b2ce34c2\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"5d0c3533a19f48e5e7e73806a3e4b29cd4364130\",\n \"lessThan\": \"694ab1f6f16cb69f7c5ef2452b22ba7b00a3c7c7\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"5d0c3533a19f48e5e7e73806a3e4b29cd4364130\",\n \"lessThan\": \"6bf4ef078fd11910988889a6c0b3698d2e0c89af\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"5d0c3533a19f48e5e7e73806a3e4b29cd4364130\",\n \"lessThan\": \"01b1d781394fc9b83015e3a3cd46b17bda842bd8\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"5d0c3533a19f48e5e7e73806a3e4b29cd4364130\",\n \"lessThan\": \"55a67ba5ac4cebfd54cc8305d4d57a0f1dfe6a85\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"5d0c3533a19f48e5e7e73806a3e4b29cd4364130\",\n \"lessThan\": \"3f747004bbd641131d9396d87b5d2d3d1e182728\",\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/dma/qcom/gpi.c\"\n ],\n \"versions\": [\n {\n \"version\": \"5.11\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"5.11\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.199\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.162\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.122\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.67\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.7\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.19\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/4532f18e4ab36def1f55cd936d0fc002b2ce34c2","https://git.kernel.org/stable/c/694ab1f6f16cb69f7c5ef2452b22ba7b00a3c7c7","https://git.kernel.org/stable/c/6bf4ef078fd11910988889a6c0b3698d2e0c89af","https://git.kernel.org/stable/c/01b1d781394fc9b83015e3a3cd46b17bda842bd8","https://git.kernel.org/stable/c/55a67ba5ac4cebfd54cc8305d4d57a0f1dfe6a85","https://git.kernel.org/stable/c/3f747004bbd641131d9396d87b5d2d3d1e182728"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-23026","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-23026","identifiers":["CVE-2026-23026"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
