This only removes a\npending timer; it does not wait for a callback that is already\nrunning and does not prevent the callback from rearming the timer.\n\nA callback running on another CPU can therefore continue after\nsnd_mtpav_free() releases the lock and access the card-private\nstate while the card is being torn down. It can also rearm the\ntimer after timer_delete() has returned.\n\nCall timer_shutdown_sync() without holding chip->spinlock. This\nwaits for any running callback to finish and prevents further\nrearming before the card-private mtpav state is released."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["sound/drivers/mtpav.c"],"versions":[{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"392c985c6b03dfdf4904c0d464f18735ca3c4df8","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"1e16e82581521a2fe20eda29bdc9e75286f7c950","status":"affected","versionType":"git"},{"version":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2","lessThan":"c73cb5b7c159246dd572277c668851a56e516019","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["sound/drivers/mtpav.c"],"versions":[{"version":"2.6.12","status":"affected"},{"version":"0","lessThan":"2.6.12","status":"unaffected","versionType":"semver"},{"version":"6.18.52","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.6","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.12","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/392c985c6b03dfdf4904c0d464f18735ca3c4df8"},{"url":"https://git.kernel.org/stable/c/1e16e82581521a2fe20eda29bdc9e75286f7c950"},{"url":"https://git.kernel.org/stable/c/c73cb5b7c159246dd572277c668851a56e516019"}],"title":"ALSA: mtpav: shut down output timer before card teardown","x_generator":{"engine":"bippy-1.2.0"}}}}
