- The overflow is reached by a plain read() of /proc/sys/dev/parport/parportN/base-addr (or autoprobe*), which requires local access to the system. No network or physical interaction is needed for the confirmed trigger path.\nAC:L - On an affected system the attacker simply opens and reads a procfs file; the overflow is deterministic and requires no race, no memory-layout grooming, and no timing. The in-the-wild report shows a reproducible stack-protector panic from a single read.\nPR:L - All affected sysctl entries are mode 0444 under 0555 directories, so any unprivileged local account — including a sandboxed or \"nobody\" user — can read them. No capability, root, or namespace privilege is involved.\nUI:N - The attacker performs the read themselves; no victim action, mount, or configuration change by another user is required.\nS:U - The corruption is confined to the kernel stack of the calling task within the same security authority; no hypervisor, IOMMU, or sandbox boundary is crossed.\nC:H - This is a stack buffer overflow past a 20-byte (and 256-byte) buffer that overwrites adjacent stack state including saved registers and the return address; in the do_autoprobe() variant the overflowing bytes are fully attacker-controlled Device ID data, giving corruption that can be leveraged into arbitrary kernel memory disclosure.\nI:H - An out-of-bounds stack write is an arbitrary-write primitive against the kernel stack, and via do_autoprobe() the written content is attacker-supplied and unbounded (~800+ bytes), making control-flow hijack and arbitrary kernel modification achievable.\nA:H - The reported real-world effect is \"Kernel panic - not syncing: stack-protector: Kernel stack is corrupted in do_hardware_base_addr\", i.e. a full system crash that any local user can trigger on demand and repeatedly."}]}],"providerMetadata":{"shortName":"Linux","orgId":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","dateUpdated":"2026-08-05T11:36:30.924Z"},"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"4.19.320"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"5.4.282"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"5.10.224"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"5.15.165"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.1.103"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.6.44"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.10.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.11"}]}]}],"x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"title":"CISA ADP Vulnrichment","metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2024-42301","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2024-09-10T16:10:32.108495Z"}}}],"providerMetadata":{"shortName":"CISA-ADP","orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","dateUpdated":"2024-09-12T17:33:05.142Z"}},{"title":"CVE Program Container","references":[{"url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"},{"url":"https://lists.debian.org/debian-lts-announce/2024/10/msg00003.html"}],"providerMetadata":{"shortName":"CVE","orgId":"af854a3a-2127-422b-91ae-364da2661108","dateUpdated":"2025-11-03T22:04:02.977Z"}}]}}}
