Such a situation may lead to an unexpected RCU stall,\nwhere  the callback repeatedly queuing the expire update, as reported\nby fuzzer.\n\nThis patch introduces a sanity check of the timer start tick time, so\nthat the system returns an error when a too small start size is set.\nAs of this patch, the lower limit is hard-coded to 100us, which is\nsmall enough but can still work somehow."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["sound/core/timer.c"],"versions":[{"version":"bbaf5e97337287479eb78dbc3822d9560bbfd2e2","lessThan":"68396c825c43664b20a3a1ba546844deb2b4e48f","status":"affected","versionType":"git"},{"version":"bbaf5e97337287479eb78dbc3822d9560bbfd2e2","lessThan":"74bfb8d90f2601718ae203faf45a196844c01fa1","status":"affected","versionType":"git"},{"version":"bbaf5e97337287479eb78dbc3822d9560bbfd2e2","lessThan":"bdd0aa055b8ec7e24bbc19513f3231958741d0ab","status":"affected","versionType":"git"},{"version":"bbaf5e97337287479eb78dbc3822d9560bbfd2e2","lessThan":"83f0ba8592b9e258fd80ac6486510ab1dcd7ad6e","status":"affected","versionType":"git"},{"version":"bbaf5e97337287479eb78dbc3822d9560bbfd2e2","lessThan":"ceab795a67dd28dd942d0d8bba648c6c0f7a044b","status":"affected","versionType":"git"},{"version":"bbaf5e97337287479eb78dbc3822d9560bbfd2e2","lessThan":"2c95241ac5fc90c929d6c0c023e84bf0d30e84c3","status":"affected","versionType":"git"},{"version":"bbaf5e97337287479eb78dbc3822d9560bbfd2e2","lessThan":"abb1ad69d98cf1ff25bb14fff0e7c3f66239e1cd","status":"affected","versionType":"git"},{"version":"bbaf5e97337287479eb78dbc3822d9560bbfd2e2","lessThan":"4a63bd179fa8d3fcc44a0d9d71d941ddd62f0c4e","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/core/timer.c"],"versions":[{"version":"2.6.29","status":"affected"},{"version":"0","lessThan":"2.6.29","status":"unaffected","versionType":"semver"},{"version":"4.19.316","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.278","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.219","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.161","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.93","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.6.33","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.9.3","lessThanOrEqual":"6.9.*","status":"unaffected","versionType":"semver"},{"version":"6.10","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":"2.6.29","versionEndExcluding":"4.19.316"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.29","versionEndExcluding":"5.4.278"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.29","versionEndExcluding":"5.10.219"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.29","versionEndExcluding":"5.15.161"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.29","versionEndExcluding":"6.1.93"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.29","versionEndExcluding":"6.6.33"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.29","versionEndExcluding":"6.9.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.29","versionEndExcluding":"6.10"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/68396c825c43664b20a3a1ba546844deb2b4e48f"},{"url":"https://git.kernel.org/stable/c/74bfb8d90f2601718ae203faf45a196844c01fa1"},{"url":"https://git.kernel.org/stable/c/bdd0aa055b8ec7e24bbc19513f3231958741d0ab"},{"url":"https://git.kernel.org/stable/c/83f0ba8592b9e258fd80ac6486510ab1dcd7ad6e"},{"url":"https://git.kernel.org/stable/c/ceab795a67dd28dd942d0d8bba648c6c0f7a044b"},{"url":"https://git.kernel.org/stable/c/2c95241ac5fc90c929d6c0c023e84bf0d30e84c3"},{"url":"https://git.kernel.org/stable/c/abb1ad69d98cf1ff25bb14fff0e7c3f66239e1cd"},{"url":"https://git.kernel.org/stable/c/4a63bd179fa8d3fcc44a0d9d71d941ddd62f0c4e"}],"title":"ALSA:
