El fallo se produce porque, aunque la estructura de datos MSI se ha liberado durante la ruta de deshabilitación/desconexión en caliente y se le ha asignado NULL, aún durante la anulación del registro el código estaba intentando de nuevo deshabilitar explícitamente el MSI, lo que provoca la desreferencia del puntero NULL y el fallo del kernel. El parche corrige la comprobación durante la ruta de anulación del registro para evitar invocar pci_disable_msi/msix() ya que su estructura de datos ya está liberada."}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","baseScore":5.5,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"NONE","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":3.6}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"CWE-476"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionEndExcluding":"4.19.322","matchCriteriaId":"29162FB8-5FA4-4DC4-86CE-5EB0CAEEF2F3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.20","versionEndExcluding":"5.4.284","matchCriteriaId":"6265A402-9C3C-438F-BFC5-4194B2568B85"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.5","versionEndExcluding":"5.10.226","matchCriteriaId":"864FC17C-501A-4823-A643-6F35D65D8A97"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"5.15.167","matchCriteriaId":"043405A4-25FE-45D4-A7BB-2A0C3B7D17C1"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"6.1.110","matchCriteriaId":"6B1A95FC-7E7E-428B-BB59-F76640C652AE"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.2","versionEndExcluding":"6.6.51","matchCriteriaId":"E4529134-BAC4-4776-840B-304009E181A0"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"6.10.10","matchCriteriaId":"ACDEE48C-137A-4731-90D0-A675865E1BED"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/335e35b748527f0c06ded9eebb65387f60647fda","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/438d522227374042b5c8798f8ce83bbe479dca4d","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/4eb4085c1346d19d4a05c55246eb93e74e671048","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/b82d4d5c736f4fd2ed224c35f554f50d1953d21e","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/bc1faed19db95abf0933b104910a3fb01b138f59","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/bfc44075b19740d372f989f21dd03168bfda0689","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/c0d8094dc740cfacf3775bbc6a1c4720459e8de4","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/c4c681999d385e28f84808bbf3a85ea8e982da55","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html","source":"af854a3a-2127-422b-91ae-364da2661108"}]}}]}
