Then we try\nto start the qgroup rescan worker, first by initializing it with a call\nto qgroup_rescan_init() - however if that fails we end up freeing the\nquota root but we leave fs_info->quota_root still pointing to it, this\ncan later result in a use-after-free somewhere else.\n\nWe have previously set the flags BTRFS_FS_QUOTA_ENABLED and\nBTRFS_QGROUP_STATUS_FLAG_ON, so we can only fail with -EINPROGRESS at\nbtrfs_quota_enable(), which is possible if someone already called the\nquota rescan ioctl, and therefore started the rescan worker.\n\nSo fix this by ignoring an -EINPROGRESS and asserting we can't get any\nother error."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/btrfs/qgroup.c"],"versions":[{"version":"5d23515be66904fa3b1b5d6bd72d2199cd2447ab","lessThan":"c97f6d528c3f1c83a6b792a8a7928c236c80b8fe","status":"affected","versionType":"git"},{"version":"5d23515be66904fa3b1b5d6bd72d2199cd2447ab","lessThan":"26b7c0ac49a3eea15559c9d84863736a6d1164b4","status":"affected","versionType":"git"},{"version":"5d23515be66904fa3b1b5d6bd72d2199cd2447ab","lessThan":"47b5ffe86332af95f0f52be0a63d4da7c2b37b55","status":"affected","versionType":"git"},{"version":"5d23515be66904fa3b1b5d6bd72d2199cd2447ab","lessThan":"4b996a3014ef014af8f97b60c35f5289210a4720","status":"affected","versionType":"git"},{"version":"5d23515be66904fa3b1b5d6bd72d2199cd2447ab","lessThan":"0efd9dfc00d677a1d0929319a6103cb2dfc41c22","status":"affected","versionType":"git"},{"version":"5d23515be66904fa3b1b5d6bd72d2199cd2447ab","lessThan":"6c22f86dd221eba0c7af645b1af73dcbc04ee27b","status":"affected","versionType":"git"},{"version":"5d23515be66904fa3b1b5d6bd72d2199cd2447ab","lessThan":"331cd9461412e103d07595a10289de90004ac890","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/btrfs/qgroup.c"],"versions":[{"version":"4.17","status":"affected"},{"version":"0","lessThan":"4.17","status":"unaffected","versionType":"semver"},{"version":"4.19.262","lessThanOrEqual":"4.19.*","status":"unaffected","versionType":"semver"},{"version":"5.4.220","lessThanOrEqual":"5.4.*","status":"unaffected","versionType":"semver"},{"version":"5.10.150","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.75","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"5.19.17","lessThanOrEqual":"5.19.*","status":"unaffected","versionType":"semver"},{"version":"6.0.3","lessThanOrEqual":"6.0.*","status":"unaffected","versionType":"semver"},{"version":"6.1","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":"4.17","versionEndExcluding":"4.19.262"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.17","versionEndExcluding":"5.4.220"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.17","versionEndExcluding":"5.10.150"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.17","versionEndExcluding":"5.15.75"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.17","versionEndExcluding":"5.19.17"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.17","versionEndExcluding":"6.0.3"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"4.17","versionEndExcluding":"6.1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/c97f6d528c3f1c83a6b792a8a7928c236c80b8fe"},{"url":"https://git.kernel.org/stable/c/26b7c0ac49a3eea15559c9d84863736a6d1164b4"},{"url":"https://git.kernel.org/stable/c/47b5ffe86332af95f0f52be0a63d4da7c2b37b55"},{"url":"https://git.kernel.org/stable/c/4b996a3014ef014af8f97b60c35f5289210a4720"},{"url":"https://git.kernel.org/stable/c/0efd9dfc00d677a1d0929319a6103cb2dfc41c22"},{"url":"https://git.kernel.org/stable/c/6c22f86dd221eba0c7af645b1af73dcbc04ee27b"},{"url":"https://git.kernel.org/stable/c/331cd9461412e103d07595a10289de90004ac890"}],"title":"btrfs:
