Este parche (de 3): Se inform\u00f3 un problema de use-after-free con respecto al temporizador sc_timer en la estructura nilfs_sc_info. El problema es que, aunque se utiliza para reactivar un subproceso de escritura de registros inactivo, sc_timer no se cierra hasta que la estructura nilfs_sc_info est\u00e1 a punto de liberarse y se utiliza independientemente de la vida \u00fatil del subproceso. Solucione este problema limitando el uso de sc_timer solo mientras el subproceso del escritor de registros est\u00e9 activo.\"}],\"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:H/I:H/A:H\",\"attackVector\":\"LOCAL\",\"attackComplexity\":\"LOW\",\"privilegesRequired\":\"LOW\",\"userInteraction\":\"NONE\",\"scope\":\"UNCHANGED\",\"confidentialityImpact\":\"HIGH\",\"integrityImpact\":\"HIGH\",\"availabilityImpact\":\"HIGH\",\"baseScore\":7.8,\"baseSeverity\":\"HIGH\"},\"exploitabilityScore\":1.8,\"impactScore\":5.9}]},\"weaknesses\":[{\"source\":\"nvd@nist.gov\",\"type\":\"Primary\",\"description\":[{\"lang\":\"en\",\"value\":\"CWE-416\"}]}],\"configurations\":[{\"nodes\":[{\"operator\":\"OR\",\"negate\":false,\"cpeMatch\":[{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"2.6.35\",\"versionEndExcluding\":\"4.19.316\",\"matchCriteriaId\":\"1BF99E52-091D-4D39-8639-6E3471FEBD3A\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"4.20\",\"versionEndExcluding\":\"5.4.278\",\"matchCriteriaId\":\"7FDBF235-DA18-49A1-8690-6C7272FD0701\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.5\",\"versionEndExcluding\":\"5.10.219\",\"matchCriteriaId\":\"E9063AF3-D593-43B7-810D-58B87F82F9F9\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.11\",\"versionEndExcluding\":\"5.15.161\",\"matchCriteriaId\":\"31130639-53FE-4726-8986-434EE2528CB2\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"5.16\",\"versionEndExcluding\":\"6.1.94\",\"matchCriteriaId\":\"9D20DE32-76F8-4E4C-A8DF-5B53082D18E5\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.2\",\"versionEndExcluding\":\"6.6.33\",\"matchCriteriaId\":\"FCE796DF-3B50-4DC6-BAE5-95271068FC9E\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.7\",\"versionEndExcluding\":\"6.8.12\",\"matchCriteriaId\":\"80550309-67AB-4FD1-AC07-3DED5C4F01B2\"},{\"vulnerable\":true,\"criteria\":\"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\",\"versionStartIncluding\":\"6.9\",\"versionEndExcluding\":\"6.9.3\",\"matchCriteriaId\":\"E07124C1-19E8-4D21-828D-9932A01D3011\"}]}]}],\"references\":[{\"url\":\"https://git.kernel.org/stable/c/2f12b2c03c5dae1a0de0a9e5853177e3d6eee3c6\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/67fa90d4a2ccd9ebb0e1e168c7d0b5d0cf3c7148\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/68e738be5c518fc3c4e9146b66f67c8fee0135fb\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/822ae5a8eac30478578a75f7e064f0584931bf2d\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/82933c84f188dcfe89eb26b0b48ab5d1ca99d164\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/86a30d6302deddb9fb97ba6fc4b04d0e870b582a\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/e65ccf3a4de4f0c763d94789615b83e11f204438\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/f5d4e04634c9cf68bdf23de08ada0bb92e8befe7\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]},{\"url\":\"https://git.kernel.org/stable/c/f9186bba4ea282b07293c1c892441df3a5441cb0\",\"source\":\"416baaa9-dc9f-4396-8d5f-8c081fb06d67\",\"tags\":[\"Patch\"]}]}}"
