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."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["net/bluetooth/hidp/core.c"], "versions": [{"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "1f08a90013e1e632b34321334e861fcefc056505", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "cc3832b19f863e3677c5651f001a2e3795f39eb8", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "d313683d6ccdd8c01e0562270a2ae25b86d8461d", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "d7d6a81b8dd1a8d084a1b755db9406041d53adb5", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "6348dfed5b0f9c6074f14322332e97493d32fef0", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "b83dcacd2ec7fcc5a48be215f82d573759f87ec2", "status": "affected", "versionType": "git"}, {"version": "1da177e4c3f41524e886b7f1b8a0c1fc7321cac2", "lessThan": "2a3ac9ee11dbb9845f3947cef4a79dba658cf6f6", "status": "affected", "versionType": "git"}]}, {"product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["net/bluetooth/hidp/core.c"], "versions": [{"version": "2.6.12", "status": "affected"}, {"version": "0", "lessThan": "2.6.12", "status": "unaffected", "versionType": "semver"}, {"version": "5.15.210", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.176", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.143", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.93", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.35", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.0.12", "lessThanOrEqual": "7.0.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1", "lessThanOrEqual": "*", "status": "unaffected", "versionType": "original_commit_for_fix"}]}], "cpeApplicability": [{"nodes": [{"operator": "OR", "negate": false, "cpeMatch": [{"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.12", "versionEndExcluding": "5.15.210"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.12", "versionEndExcluding": "6.1.176"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.12", "versionEndExcluding": "6.6.143"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.12", "versionEndExcluding": "6.12.93"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.12", "versionEndExcluding": "6.18.35"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.12", "versionEndExcluding": "7.0.12"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "2.6.12", "versionEndExcluding": "7.1"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/1f08a90013e1e632b34321334e861fcefc056505"}, {"url": "https://git.kernel.org/stable/c/cc3832b19f863e3677c5651f001a2e3795f39eb8"}, {"url": "https://git.kernel.org/stable/c/d313683d6ccdd8c01e0562270a2ae25b86d8461d"}, {"url": "https://git.kernel.org/stable/c/d7d6a81b8dd1a8d084a1b755db9406041d53adb5"}, {"url": "https://git.kernel.org/stable/c/6348dfed5b0f9c6074f14322332e97493d32fef0"}, {"url": "https://git.kernel.org/stable/c/b83dcacd2ec7fcc5a48be215f82d573759f87ec2"}, {"url": "https://git.kernel.org/stable/c/2a3ac9ee11dbb9845f3947cef4a79dba658cf6f6"}], "title": "Bluetooth: HIDP: fix missing length checks in hidp_input_report()", "x_generator": {"engine": "bippy-1.2.0"}}}}
