A parked\nthread doesn't need that wakeup to leave. A spurious wakeup or a\npreemption after the store is enough for the task to go away.\n\nSo if the coredump client is preempted between the store and\nwake_up_process() the thread can exit and be freed in the meantime and\ntry_to_wake_up() takes pi_lock in freed memory.\n\nHold rcu across the loop."}],"affected":[{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","affectedData":[{"vendor":"Linux","product":"Linux","defaultStatus":"unaffected","programFiles":["fs/coredump.c"],"repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","versions":[{"version":"a94e2d408eaedbd85aae259621d46fafc10479a2","lessThan":"fd0fbe84312fda2fc187428c92c50b7d03a9d24c","versionType":"git","status":"affected"},{"version":"a94e2d408eaedbd85aae259621d46fafc10479a2","lessThan":"71146c437bae59e5280f657965dc6d006ee3989b","versionType":"git","status":"affected"},{"version":"a94e2d408eaedbd85aae259621d46fafc10479a2","lessThan":"0fce73efee40c65ce26641c5d93942462f9e8307","versionType":"git","status":"affected"},{"version":"a94e2d408eaedbd85aae259621d46fafc10479a2","lessThan":"16e94ed90b1b02398e044d41fd1db34828daa08e","versionType":"git","status":"affected"},{"version":"a94e2d408eaedbd85aae259621d46fafc10479a2","lessThan":"a0f09ff4c6b93312e565cfe75d76c3a551a3ec4c","versionType":"git","status":"affected"},{"version":"a94e2d408eaedbd85aae259621d46fafc10479a2","lessThan":"b0eca0edddf4c1dbaf6d1f6a8636b4235f5bc573","versionType":"git","status":"affected"}]},{"vendor":"Linux","product":"Linux","defaultStatus":"affected","programFiles":["fs/coredump.c"],"repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","versions":[{"version":"2.6.27","status":"affected"},{"version":"0","lessThan":"2.6.27","versionType":"semver","status":"unaffected"},{"version":"6.1.191","lessThanOrEqual":"6.1.*","versionType":"semver","status":"unaffected"},{"version":"6.6.161","lessThanOrEqual":"6.6.*","versionType":"semver","status":"unaffected"},{"version":"6.12.115","lessThanOrEqual":"6.12.*","versionType":"semver","status":"unaffected"},{"version":"6.18.60","lessThanOrEqual":"6.18.*","versionType":"semver","status":"unaffected"},{"version":"7.2.14","lessThanOrEqual":"7.2.*","versionType":"semver","status":"unaffected"},{"version":"7.3.1","lessThanOrEqual":"7.3.*","versionType":"semver","status":"unaffected"}]}]}],"metrics":{"cvssMetricV31":[{"source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","type":"Secondary","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}]},"references":[{"url":"https://git.kernel.org/stable/c/0fce73efee40c65ce26641c5d93942462f9e8307","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/16e94ed90b1b02398e044d41fd1db34828daa08e","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/71146c437bae59e5280f657965dc6d006ee3989b","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/a0f09ff4c6b93312e565cfe75d76c3a551a3ec4c","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/b0eca0edddf4c1dbaf6d1f6a8636b4235f5bc573","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"},{"url":"https://git.kernel.org/stable/c/fd0fbe84312fda2fc187428c92c50b7d03a9d24c","source":"416baaa9-dc9f-4396-8d5f-8c081fb06d67"}]}}]}
