the Linux kernel, the following vulnerability has been resolved:\n\ngfs2: Fix possible data races in gfs2_show_options()\n\nSome fields such as gt_logd_secs of the struct gfs2_tune are accessed\nwithout holding the lock gt_spin in gfs2_show_options():\n\n  val = sdp->sd_tune.gt_logd_secs;\n  if (val != 30)\n    seq_printf(s, \",commit=%d\", val);\n\nAnd thus can cause data races when gfs2_show_options() and other functions\nsuch as gfs2_reconfigure() are concurrently executed:\n\n  spin_lock(&gt->gt_spin);\n  gt->gt_logd_secs = newargs->ar_commit;\n\nTo fix these possible data races, the lock sdp->sd_tune.gt_spin is\nacquired before accessing the fields of gfs2_tune and released after these\naccesses.\n\nFurther changes by Andreas:\n\n- Don't hold the spin lock over the seq_printf operations."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/gfs2/super.c"],"versions":[{"version":"48c2b613616235d7c97fda5982f50100a6c79166","lessThan":"7e5bbeb7eb813bb2568e1d5d02587df943272e57","status":"affected","versionType":"git"},{"version":"48c2b613616235d7c97fda5982f50100a6c79166","lessThan":"235a5ae73cea29109a3e06f100493f17857e6a93","status":"affected","versionType":"git"},{"version":"48c2b613616235d7c97fda5982f50100a6c79166","lessThan":"b4a7ab57effbed42624842f2ab2a49b177c21a47","status":"affected","versionType":"git"},{"version":"48c2b613616235d7c97fda5982f50100a6c79166","lessThan":"7c5b2649f6a37d45bfb7abf34c9b71d08677139f","status":"affected","versionType":"git"},{"version":"48c2b613616235d7c97fda5982f50100a6c79166","lessThan":"85e888150075cb221270b64bf772341fc6bd11d9","status":"affected","versionType":"git"},{"version":"48c2b613616235d7c97fda5982f50100a6c79166","lessThan":"a4f71523ed2123d63b431cc0cea4e9f363a0f054","status":"affected","versionType":"git"},{"version":"48c2b613616235d7c97fda5982f50100a6c79166","lessThan":"42077d4de49e4d9c773c97c42d5383b4899a8f9d","status":"affected","versionType":"git"},{"version":"48c2b613616235d7c97fda5982f50100a6c79166","lessThan":"6fa0a72cbbe45db4ed967a51f9e6f4e3afe61d20","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/gfs2/super.c"],"versions":[{"version":"2.6.31","status":"affected"},{"version":"0","lessThan":"2.6.31","status":"unaffected","versionType":"semver"},{"version":"4.14.324","lessThanOrEqual":"4.14.*","status":"unaffected","versionType":"semver"},{"version":"4.19.293","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.255","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.192","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.128","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.47","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.4.12","lessThanOrEqual":"6.4.*","status":"unaffected","versionType":"semver"},{"version":"6.5","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":"2.6.31","versionEndExcluding":"4.14.324"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.31","versionEndExcluding":"4.19.293"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.31","versionEndExcluding":"5.4.255"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.31","versionEndExcluding":"5.10.192"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.31","versionEndExcluding":"5.15.128"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.31","versionEndExcluding":"6.1.47"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.31","versionEndExcluding":"6.4.12"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"2.6.31","versionEndExcluding":"6.5"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/7e5bbeb7eb813bb2568e1d5d02587df943272e57"},{"url":"https://git.kernel.org/stable/c/235a5ae73cea29109a3e06f100493f17857e6a93"},{"url":"https://git.kernel.org/stable/c/b4a7ab57effbed42624842f2ab2a49b177c21a47"},{"url":"https://git.kernel.org/stable/c/7c5b2649f6a37d45bfb7abf34c9b71d08677139f"},{"url":"https://git.kernel.org/stable/c/85e888150075cb221270b64bf772341fc6bd11d9"},{"url":"https://git.kernel.org/stable/c/a4f71523ed2123d63b431cc0cea4e9f363a0f054"},{"url":"https://git.kernel.org/stable/c/42077d4de49e4d9c773c97c42d5383b4899a8f9d"},{"url":"https://git.kernel.org/stable/c/6fa0a72cbbe45db4ed967a51f9e6f4e3afe61d20"}],"title":"gfs2:
