La antigua función 'txtimer' se divide en 'txfrtimer' y 'txtimer' para manejar las dos funcionalidades anteriores con devoluciones de llamadas de temporizador independientes. Los dos temporizadores simplificados ahora se ejecutan en modo de una sola vez y hacen que las transiciones de estado (especialmente con isotp_rcv_echo) sean mejor comprensibles."}],"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":"NVD-CWE-noinfo"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.0.9","versionEndExcluding":"6.1","matchCriteriaId":"28CC5A62-2D03-429C-A726-BF09788C85CA"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.1.1","versionEndExcluding":"6.1.11","matchCriteriaId":"7C5214A4-3205-4DBA-8381-6D8319C38AE5"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.1:-:*:*:*:*:*:*","matchCriteriaId":"DE093B34-F4CD-4052-8122-730D6537A91A"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.1:rc5:*:*:*:*:*:*","matchCriteriaId":"35B26BE4-43A6-4A36-A7F6-5B3F572D9186"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.1:rc6:*:*:*:*:*:*","matchCriteriaId":"3FFFB0B3-930D-408A-91E2-BAE0C2715D80"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.1:rc7:*:*:*:*:*:*","matchCriteriaId":"8535320E-A0DB-4277-800E-D0CE5BBA59E8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.1:rc8:*:*:*:*:*:*","matchCriteriaId":"21718AA4-4056-40F2-968E-BDAA465A7872"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.2:rc1:*:*:*:*:*:*","matchCriteriaId":"FF501633-2F44-4913-A8EE-B021929F49F6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.2:rc2:*:*:*:*:*:*","matchCriteriaId":"2BDA597B-CAC1-4DF0-86F0-42E142C654E9"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.2:rc3:*:*:*:*:*:*","matchCriteriaId":"725C78C9-12CE-406F-ABE8-0813A01D66E8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.2:rc4:*:*:*:*:*:*","matchCriteriaId":"A127C155-689C-4F67-B146-44A57F4BFD85"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.2:rc5:*:*:*:*:*:*","matchCriteriaId":"D34127CC-68F5-4703-A5F6-5006F803E4AE"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:6.2:rc6:*:*:*:*:*:*","matchCriteriaId":"4AB8D555-648E-4F2F-98BD-3E7F45BD12A8"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/4f027cba8216f42a18b544842efab134f8b1f9f4","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/cae4c9bc35f72af5d4a079bb9d9fd62c4088a411","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]}]}}]}
