there is no network, adjacent-network, or removable-device ingress, so reaching it requires local presence on the affected laptop.\nAC:L - On affected hardware the array is unconditionally unterminated, so `property_entry_get()` reads out of bounds deterministically on every property lookup for the bridged amp \u2014 no race, timing window, or memory grooming is needed for the OOB access itself.\nPR:L - The OOB walk executes automatically during device probe with no attacker-supplied input, so an ordinary unprivileged local account on the machine is the lowest bar that meaningfully applies; no capability check gates the code path itself.\nUI:N - The bad software node is created and parsed during driver probe at boot or module load; no victim action such as opening a file or mounting a filesystem is required.\nS:U - The out-of-bounds read and any resulting fault are entirely within the kernel's own security authority \u2014 no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - The walk is unbounded \u2014 it continues until it happens to find a zero `.name` \u2014 and passes attacker-uninfluenced heap words to `strcmp()` as pointers, producing an unbounded slab OOB read plus dereference of effectively arbitrary kernel addresses rather than a few strictly bounded bytes.\nI:L - There is no OOB write or OOB free (`property_entries_free()` is unreachable since the node is not `allocated`, and the memcpy is length-checked), but a bogus entry accepted from past-the-end memory can supply a wrong speaker ID that changes the DSP firmware file selected via `\"%04x%04x-spkid%d\"`, giving limited modification of driver state.\nA:H - Dereferencing the garbage `.name` pointer in `strcmp()` faults in kernel context, which is exactly the failure the commit and bugzilla 220371 describe \u2014 an oops during probe that leaves audio and potentially the boot unusable."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["drivers/spi/spi-cs42l43.c"], "versions": [{"version": "0ca645ab5b1528666f6662a0e620140355b5aea3", "lessThan": "674328102baad76c7a06628efc01974ece5ae27f", "status": "affected", "versionType": "git"}, {"version": "0ca645ab5b1528666f6662a0e620140355b5aea3", "lessThan": "9f0035ae38d2571f5ddedc829d74492013caa625", "status": "affected", "versionType": "git"}, {"version": "0ca645ab5b1528666f6662a0e620140355b5aea3", "lessThan": "139b5df757a0aa436f763b0038e0b73808d2f4b6", "status": "affected", "versionType": "git"}, {"version": "0ca645ab5b1528666f6662a0e620140355b5aea3", "lessThan": "ffcfd071eec7973e58c4ffff7da4cb0e9ca7b667", "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/spi/spi-cs42l43.c"], "versions": [{"version": "6.11", "status": "affected"}, {"version": "0", "lessThan": "6.11", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.42", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.15.10", "lessThanOrEqual": "6.15.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.16.1", "lessThanOrEqual": "6.16.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.17", "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": "6.11", "versionEndExcluding": "6.12.42"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.11", "versionEndExcluding": "6.15.10"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.11", "versionEndExcluding": "6.16.1"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "6.11", "versionEndExcluding": "6.17"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/674328102baad76c7a06628efc01974ece5ae27f"}, {"url": "https://git.kernel.org/stable/c/9f0035ae38d2571f5ddedc829d74492013caa625"}, {"url": "https://git.kernel.org/stable/c/139b5df757a0aa436f763b0038e0b73808d2f4b6"}, {"url": "https://git.kernel.org/stable/c/ffcfd071eec7973e58c4ffff7da4cb0e9ca7b667"}], "title": "spi: cs42l43: Property entry should be a null-terminated array", "x_generator": {"engine": "bippy-1.2.0"}}}}
