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."}]}],"providerMetadata":{"shortName":"Linux","orgId":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","dateUpdated":"2026-08-05T09:12:29.445Z"},"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"}]}]}],"x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2023-53039","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2026-10-15T21:33:12.390467Z"}}}],"providerMetadata":{"shortName":"CISA-ADP","orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","dateUpdated":"2026-10-15T21:41:25.343Z"}}]}}}
