Then, as it calls exit_itimers, posix_cpu_timer_del cannot find\nthe task because the timer still points out to the old PID.\n\nThat means that armed timers won't be disarmed, that is, they won't be\nremoved from the timerqueue_list. exit_itimers will still release their\nmemory, and when that list is later processed, it leads to a\nuse-after-free.\n\nClean up the timers from the de-threaded task before freeing them.

Cuando un subproceso no líder llama a execve, intercambia los PID con el proceso líder. Luego, al llamar a exit_itimers, posix_cpu_timer_del no puede encontrar la tarea porque el temporizador aún apunta al PID anterior. Esto significa que los temporizadores armados no se desarmarán; es decir, no se eliminarán de timerqueue_list. exit_itimers liberará su memoria y, cuando esa lista se procese posteriormente, se generará un Use-After-Free. Limpie los temporizadores de la tarea desprovista de subprocesos antes de liberarlos. Esto evita un Use-After-Free reportado."}],"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","baseScore":7.8,"baseSeverity":"HIGH","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"LOW","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"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":"5.7","versionEndExcluding":"5.10.137","matchCriteriaId":"674AABE4-BC3E-4530-9717-5DFE7AB70A3F"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.11","versionEndExcluding":"5.15.61","matchCriteriaId":"51861563-7F40-460F-82CD-2D3FBDAD6618"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"5.18.18","matchCriteriaId":"5B42E453-8837-49D0-A5EF-03F818A6DC11"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.19","versionEndExcluding":"5.19.2","matchCriteriaId":"A1A2A5A5-4598-4D7E-BA07-4660398D6C8F"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/541840859ace9c2ccebc32fa9e376c7bd3def490","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/9e255ed238fc67058df87b0388ad6d4b2ef3a2bd","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/b2fc1723eb65abb83e00d5f011de670296af0b28","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/e362359ace6f87c201531872486ff295df306d13","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]},{"url":"https://git.kernel.org/stable/c/e8cb6e8fd9890780f1bfcf5592889e1b879e779c","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","tags":["Patch"]}]}}]}
