La disminución del número de dst debe ocurrir antes. Notas: 1) en el caso de CONFIG_XFRM, dst_destroy() puede llamar a dst_release_immediate(child), lo que también podría causar UAF si el hijo no tiene DST_NOCOUNT configurado. Los encargados del mantenimiento de IPSEC podrían echar un vistazo y ver cómo solucionar esto. 2) También se está discutiendo sobre la eliminación de este recuento de dst, lo que podría suceder en kernels futuros."}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","baseScore":7.0,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"HIGH","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":1.0,"impactScore":5.9}]},"weaknesses":[{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"NVD-CWE-noinfo"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.10.50","versionEndExcluding":"3.11","matchCriteriaId":"EB008871-978A-402A-8407-15291079DC44"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.12.26","versionEndExcluding":"3.13","matchCriteriaId":"597B9ABF-E2FF-405B-8226-0BD990181032"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.14.14","versionEndExcluding":"3.15","matchCriteriaId":"6241E34F-0DAB-4BE0-AD33-1BEEDA5841C9"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.15.7","versionEndExcluding":"3.16","matchCriteriaId":"F88CDBE1-4ECE-4BE4-B2A6-7E814D3EA822"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.16","versionEndExcluding":"6.6.57","matchCriteriaId":"8D4764C3-4502-4F9B-8704-85262723C867"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.7","versionEndExcluding":"6.11.4","matchCriteriaId":"AA84D336-CE9A-4535-B901-1AD77EC17C34"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.12:rc1:*:*:*:*:*:*","matchCriteriaId":"7F361E1D-580F-4A2D-A509-7615F73167A1"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.12:rc2:*:*:*:*:*:*","matchCriteriaId":"925478D0-3E3D-4E6F-ACD5-09F28D5DF82C"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/3c7c918ec0aa3555372c5a57f18780b7a96c5cfc","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/547087307bc19417b4f2bc85ba9664a3e8db5a6a","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/a60db84f772fc3a906c6c4072f9207579c41166f","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/ac888d58869bb99753e7652be19a151df9ecb35d","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/e3915f028b1f1c37e87542e5aadd33728c259d96","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/eae7435b48ffc8e9be0ff9cfeae40af479a609dd","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"},{"url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html","source":"af854a3a-2127-422b-91ae-364da2661108"}]}}]}
