There is no remote or network-facing entry to `eeh_pe_bus_get()`.\nAC:L - The attacker drives the racing side (device removal) while the recovery sequence holds the stale `edev->pdev` across `eeh_pe_report()` driver callbacks and `eeh_wait_state()` waits of up to 300 seconds, and `eeh_pe_bus_get()` is reached at multiple points in that sequence, giving a wide and repeatable window.\nPR:L - Entry into the vulnerable recovery path requires no privileges — `eeh_check_failure()`/`eeh_dev_check_failure()`/`eeh_send_failure_ev ent()` perform no capability check, so ordinary unprivileged I/O on an affected PCI device queues the EEH event that reaches `eeh_pe_bus_get()`.\nUI:N - No victim action is needed; the EEH event is queued automatically by the MMIO accessor macros and the recovery kthread runs on its own.\nS:U - The stale dereference and any resulting corruption stay within the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free read of a `kfree()`d `struct pci_dev`, and the value read (`pdev->bus`) is propagated into further dereferences in `eeh_pe_loc_get_bus()` and the PCI hotplug core, so a reallocated and groomed slab yields an attacker-chosen pointer that the kernel then follows and exposes.\nI:H - The stale/attacker-influenced `struct pci_bus *` is handed to `pci_hp_remove_devices()` and `pci_hp_add_devices()`, which walk and unlink device lists through it, turning the UAF into list corruption and a write primitive exploitable for control-flow hijacking.\nA:H - The commit explicitly describes a crash; dereferencing a freed or concurrently NULLed `edev->pdev` oopses the `eehd` kthread and derails PCI error recovery, leaving the affected devices unusable."}]}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["arch/powerpc/kernel/eeh_pe.c"],"versions":[{"version":"9b3c76f08122f5efdbe4992a64b8478cc92dd983","lessThan":"8836e1bf5838ac6c08760e0a2dd7cf6410aa7ff3","status":"affected","versionType":"git"},{"version":"9b3c76f08122f5efdbe4992a64b8478cc92dd983","lessThan":"033c51dfdbb6b79ab43fb3587276fa82d0a329e1","status":"affected","versionType":"git"},{"version":"9b3c76f08122f5efdbe4992a64b8478cc92dd983","lessThan":"4fad7fef847b6028475dd7b4c14fcb82b3e51274","status":"affected","versionType":"git"},{"version":"9b3c76f08122f5efdbe4992a64b8478cc92dd983","lessThan":"4bc246d2d60d071314842fa448faa4ed39082aff","status":"affected","versionType":"git"},{"version":"9b3c76f08122f5efdbe4992a64b8478cc92dd983","lessThan":"f23c3d1ca9c4b2d626242a4e7e1ec1770447f7b5","status":"affected","versionType":"git"},{"version":"9b3c76f08122f5efdbe4992a64b8478cc92dd983","lessThan":"428d940a8b6b3350b282c14d3f63350bde65c48b","status":"affected","versionType":"git"},{"version":"9b3c76f08122f5efdbe4992a64b8478cc92dd983","lessThan":"a1216e62d039bf63a539bbe718536ec789a853dd","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["arch/powerpc/kernel/eeh_pe.c"],"versions":[{"version":"3.7","status":"affected"},{"version":"0","lessThan":"3.7","status":"unaffected","versionType":"semver"},{"version":"5.4.281","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.223","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.164","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.101","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.42","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.9.11","lessThanOrEqual":"6.9.*","status":"unaffected","versionType":"semver"},{"version":"6.10","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":"3.7","versionEndExcluding":"5.4.281"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.7","versionEndExcluding":"5.10.223"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.7","versionEndExcluding":"5.15.164"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.7","versionEndExcluding":"6.1.101"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.7","versionEndExcluding":"6.6.42"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.7","versionEndExcluding":"6.9.11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.7","versionEndExcluding":"6.10"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/8836e1bf5838ac6c08760e0a2dd7cf6410aa7ff3"},{"url":"https://git.kernel.org/stable/c/033c51dfdbb6b79ab43fb3587276fa82d0a329e1"},{"url":"https://git.kernel.org/stable/c/4fad7fef847b6028475dd7b4c14fcb82b3e51274"},{"url":"https://git.kernel.org/stable/c/4bc246d2d60d071314842fa448faa4ed39082aff"},{"url":"https://git.kernel.org/stable/c/f23c3d1ca9c4b2d626242a4e7e1ec1770447f7b5"},{"url":"https://git.kernel.org/stable/c/428d940a8b6b3350b282c14d3f63350bde65c48b"},{"url":"https://git.kernel.org/stable/c/a1216e62d039bf63a539bbe718536ec789a853dd"}],"title":"powerpc/eeh:
