This will cause the incoming call to be aborted.","state":0,"publishedAt":"2025-08-16T10:55:01.15+00:00","modifiedAt":"2026-10-15T21:52:18.287+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/rxrpc/call_accept.c\"\n ],\n \"versions\": [\n {\n \"version\": \"248f219cb8bcbfbd7f132752d44afa2df7c241d1\",\n \"lessThan\": \"bf0ca6a1bc4fb904b598137c6718785a107e3adf\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"248f219cb8bcbfbd7f132752d44afa2df7c241d1\",\n \"lessThan\": \"f7afb3ff01c42c49e8a143cdce400b95844bb506\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"248f219cb8bcbfbd7f132752d44afa2df7c241d1\",\n \"lessThan\": \"f5e72b7824d08c206ce106d30cb37c4642900ccc\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"248f219cb8bcbfbd7f132752d44afa2df7c241d1\",\n \"lessThan\": \"0eef29385d715d4c7fd707b18d4a9b76c76dd5e6\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"248f219cb8bcbfbd7f132752d44afa2df7c241d1\",\n \"lessThan\": \"efc1b2b7c1a308b60df8f36bc2d7ce16d3999364\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"248f219cb8bcbfbd7f132752d44afa2df7c241d1\",\n \"lessThan\": \"d1ff5f9d2c5405681457262e23c720b08977c11f\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"248f219cb8bcbfbd7f132752d44afa2df7c241d1\",\n \"lessThan\": \"2c2e9ebeb036f9b1b09325ec5cfdfe0e78f357c3\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"248f219cb8bcbfbd7f132752d44afa2df7c241d1\",\n \"lessThan\": \"880a88f318cf1d2a0f4c0a7ff7b07e2062b434a4\",\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/rxrpc/call_accept.c\"\n ],\n \"versions\": [\n {\n \"version\": \"4.9\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"4.9\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.4.296\",\n \"lessThanOrEqual\": \"5.4.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.10.240\",\n \"lessThanOrEqual\": \"5.10.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.189\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.146\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.99\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.39\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.15.7\",\n \"lessThanOrEqual\": \"6.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.16\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/bf0ca6a1bc4fb904b598137c6718785a107e3adf","https://git.kernel.org/stable/c/f7afb3ff01c42c49e8a143cdce400b95844bb506","https://git.kernel.org/stable/c/f5e72b7824d08c206ce106d30cb37c4642900ccc","https://git.kernel.org/stable/c/0eef29385d715d4c7fd707b18d4a9b76c76dd5e6","https://git.kernel.org/stable/c/efc1b2b7c1a308b60df8f36bc2d7ce16d3999364","https://git.kernel.org/stable/c/d1ff5f9d2c5405681457262e23c720b08977c11f","https://git.kernel.org/stable/c/2c2e9ebeb036f9b1b09325ec5cfdfe0e78f357c3","https://git.kernel.org/stable/c/880a88f318cf1d2a0f4c0a7ff7b07e2062b434a4"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2025-38514","license":"CVE Program Terms of Use","key":"cve-program:CVE-2025-38514","identifiers":["CVE-2025-38514"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
