Turns out the compression path will complete\nthe bio we use if we set up any of the compression bios and then return\nan error, and then btrfs_submit_data_bio() will also call bio_endio() on\nthe bio.\n\nFix this by making btrfs_submit_compressed_read() responsible for\ncalling bio_endio() on the bio if there are any errors.  Currently it\nwas only doing it if we created the compression bios, otherwise it was\ndepending on btrfs_submit_data_bio() to do the right thing.  This\ncreates the above problem, so fix up btrfs_submit_compressed_read() to\nalways call bio_endio() in case of an error, and then simply return from\nbtrfs_submit_data_bio() if we had to call\nbtrfs_submit_compressed_read()."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/btrfs/compression.c","fs/btrfs/inode.c"],"versions":[{"version":"86ccbb4d2a2af4109430df518c995a4f7d14dfd2","lessThan":"4a4ceb2b990771c374d85d496a1a45255dde48e3","status":"affected","versionType":"git"},{"version":"86ccbb4d2a2af4109430df518c995a4f7d14dfd2","lessThan":"987b5df1d10355d377315a26e7fb6c72ded83c9f","status":"affected","versionType":"git"},{"version":"86ccbb4d2a2af4109430df518c995a4f7d14dfd2","lessThan":"f9f15de85d74e7eef021af059ca53a15f041cdd8","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/compression.c","fs/btrfs/inode.c"],"versions":[{"version":"5.16","status":"affected"},{"version":"0","lessThan":"5.16","status":"unaffected","versionType":"semver"},{"version":"5.16.19","lessThanOrEqual":"5.16.*","status":"unaffected","versionType":"semver"},{"version":"5.17.2","lessThanOrEqual":"5.17.*","status":"unaffected","versionType":"semver"},{"version":"5.18","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":"5.16","versionEndExcluding":"5.16.19"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"5.17.2"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.16","versionEndExcluding":"5.18"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/4a4ceb2b990771c374d85d496a1a45255dde48e3"},{"url":"https://git.kernel.org/stable/c/987b5df1d10355d377315a26e7fb6c72ded83c9f"},{"url":"https://git.kernel.org/stable/c/f9f15de85d74e7eef021af059ca53a15f041cdd8"}],"title":"btrfs: do not double complete bio on errors during compressed reads","x_generator":{"engine":"bippy-1.2.0"}}}}
