Reachability requires local access on a system with ISH, matching other intel-ish-hid scores (AV:L, not AV:P).\nAC:L - This is a use-after-free from scheduling fw_reset_work without cancelling it on probe failure/teardown; UAF bugs are AC:L unless the attacker cannot influence the race. Driver bind/teardown and FW reset notify give a practical way to drive both sides of the lifecycle race.\nPR:L - No capability-gated syscall is required to be on the system when ISH probe fails or FW reset work runs against freed state; related ISH reset and probe-error work bugs are scored PR:L. Deliberate sysfs unbind would be PR:H, so PR:L is chosen as the higher-severity defensible option.\nUI:N - Exploitation does not require a victim to perform an action such as opening a file or clicking; the work is scheduled from the ISH ISR/firmware reset path during driver probe/teardown.\nS:U - Impact is confined to the host kernel's security authority (memory corruption/privilege escalation in kernel context), with no VM, IOMMU, or other security-boundary crossing.\nC:H - Use-after-free of ishtp_device via the global ishtp_dev pointer in fw_reset_work_fn enables reclaim and controlled reuse of the object, which can be leveraged for arbitrary kernel memory disclosure.\nI:H - The same UAF on a rich ishtp_device object (lists, callbacks, HW ops) enables heap reuse for arbitrary write and control-flow hijacking in kernel context.\nA:H - Dereferencing freed ishtp_dev in the reset work path causes kernel oops/panic even without full exploitation, so availability impact is High." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/hid/intel-ish-hid/ipc/ipc.c" ], "versions": [ { "version": "ae02e5d40d5f829c589412c6253f925e35cf7a22", "lessThan": "8c1d378b8c224fd50247625255f09fc01dcc5836", "status": "affected", "versionType": "git" }, { "version": "ae02e5d40d5f829c589412c6253f925e35cf7a22", "lessThan": "0a594cb490ca6232671fc09e2dc1a0fc7ccbb0b5", "status": "affected", "versionType": "git" }, { "version": "ae02e5d40d5f829c589412c6253f925e35cf7a22", "lessThan": "d3ce3afd9f791dd1b7daedfcf8c396b60af5dec0", "status": "affected", "versionType": "git" }, { "version": "ae02e5d40d5f829c589412c6253f925e35cf7a22", "lessThan": "8ae2f2b0a28416ed2f6d8478ac8b9f7862f36785", "status": "affected", "versionType": "git" } ] }, { "product": "Linux", "vendor": "Linux", "defaultStatus": "affected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [ "drivers/hid/intel-ish-hid/ipc/ipc.c" ], "versions": [ { "version": "4.9", "status": "affected" }, { "version": "0", "lessThan": "4.9", "status": "unaffected", "versionType": "semver" }, { "version": "5.15.105", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.1.22", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.2.9", "lessThanOrEqual": "6.2.*", "status": "unaffected", "versionType": "semver" }, { "version": "6.3", "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": "4.9", "versionEndExcluding": "5.15.105" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.9", "versionEndExcluding": "6.1.22" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.9", "versionEndExcluding": "6.2.9" }, { "vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "4.9", "versionEndExcluding": "6.3" } ] } ] } ], "references": [ { "url": "https://git.kernel.org/stable/c/8c1d378b8c224fd50247625255f09fc01dcc5836" }, { "url": "https://git.kernel.org/stable/c/0a594cb490ca6232671fc09e2dc1a0fc7ccbb0b5" }, { "url": "https://git.kernel.org/stable/c/d3ce3afd9f791dd1b7daedfcf8c396b60af5dec0" }, { "url": "https://git.kernel.org/stable/c/8ae2f2b0a28416ed2f6d8478ac8b9f7862f36785" } ], "title": "HID: intel-ish-hid: ipc: Fix potential use-after-free in work function", "x_generator": { "engine": "bippy-1.2.0" } } } }
