If a paired device sends a truncated packet,\nthe handler reads beyond the valid skb data, resulting in an\nout-of-bounds read of skb data. The OOB bytes may be interpreted as\nphantom key presses or spurious mouse movement.\n\nReplace the open-coded length tracking and pointer arithmetic with\nskb_pull_data() calls. skb_pull_data() returns NULL if the requested\nbytes are not present, eliminating the need for a manual size variable\nand the separate skb->len guard.","state":0,"publishedAt":"2026-07-19T14:55:41.306+00:00","modifiedAt":"2026-10-19T20:17:58.868+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/bluetooth/hidp/core.c\"\n ],\n \"versions\": [\n {\n \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n \"lessThan\": \"1f08a90013e1e632b34321334e861fcefc056505\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n \"lessThan\": \"cc3832b19f863e3677c5651f001a2e3795f39eb8\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n \"lessThan\": \"d313683d6ccdd8c01e0562270a2ae25b86d8461d\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n \"lessThan\": \"d7d6a81b8dd1a8d084a1b755db9406041d53adb5\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n \"lessThan\": \"6348dfed5b0f9c6074f14322332e97493d32fef0\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n \"lessThan\": \"b83dcacd2ec7fcc5a48be215f82d573759f87ec2\",\n \"status\": \"affected\",\n \"versionType\": \"git\"\n },\n {\n \"version\": \"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2\",\n \"lessThan\": \"2a3ac9ee11dbb9845f3947cef4a79dba658cf6f6\",\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/bluetooth/hidp/core.c\"\n ],\n \"versions\": [\n {\n \"version\": \"2.6.12\",\n \"status\": \"affected\"\n },\n {\n \"version\": \"0\",\n \"lessThan\": \"2.6.12\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"5.15.210\",\n \"lessThanOrEqual\": \"5.15.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.1.176\",\n \"lessThanOrEqual\": \"6.1.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.6.143\",\n \"lessThanOrEqual\": \"6.6.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.12.93\",\n \"lessThanOrEqual\": \"6.12.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"6.18.35\",\n \"lessThanOrEqual\": \"6.18.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.0.12\",\n \"lessThanOrEqual\": \"7.0.*\",\n \"status\": \"unaffected\",\n \"versionType\": \"semver\"\n },\n {\n \"version\": \"7.1\",\n \"lessThanOrEqual\": \"*\",\n \"status\": \"unaffected\",\n \"versionType\": \"original_commit_for_fix\"\n }\n ]\n }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","score":8.8,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/1f08a90013e1e632b34321334e861fcefc056505","https://git.kernel.org/stable/c/cc3832b19f863e3677c5651f001a2e3795f39eb8","https://git.kernel.org/stable/c/d313683d6ccdd8c01e0562270a2ae25b86d8461d","https://git.kernel.org/stable/c/d7d6a81b8dd1a8d084a1b755db9406041d53adb5","https://git.kernel.org/stable/c/6348dfed5b0f9c6074f14322332e97493d32fef0","https://git.kernel.org/stable/c/b83dcacd2ec7fcc5a48be215f82d573759f87ec2","https://git.kernel.org/stable/c/2a3ac9ee11dbb9845f3947cef4a79dba658cf6f6"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-63947","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-63947","identifiers":["CVE-2026-63947"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
