If ish_probe() fails, the devm-managed device resources\nincluding ishtp_dev are freed, but the work is not cancelled, causing a\nuse-after-free when the work function tries to access ishtp_dev.

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"}}}}
