This\noccurs because the if statement to decide if we should abort is wrong.\n\nThe only way we would abort in this case is if we got a ret !=\n-EOPNOTSUPP and we called from the file clone code.  However the\nprealloc code uses this path too.  Instead we need to abort if there is\nan error, and the only error we _don't_ abort on is -EOPNOTSUPP and only\nif we came from the clone file code."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/btrfs/file.c"],"versions":[{"version":"8fccebfa534c7984864394fa03608305e4929aae","lessThan":"0e32a2b85c7d92ece86c17dfef390c5ed79c6378","status":"affected","versionType":"git"},{"version":"8fccebfa534c7984864394fa03608305e4929aae","lessThan":"0e309e1152fc34ef75991d9d69b165dbf75bf26c","status":"affected","versionType":"git"},{"version":"8fccebfa534c7984864394fa03608305e4929aae","lessThan":"4afb912f439c4bc4e6a4f3e7547f2e69e354108f","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/file.c"],"versions":[{"version":"5.10","status":"affected"},{"version":"0","lessThan":"5.10","status":"unaffected","versionType":"semver"},{"version":"5.10.75","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.14.14","lessThanOrEqual":"5.14.*","status":"unaffected","versionType":"semver"},{"version":"5.15","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":"5.10","versionEndExcluding":"5.10.75"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"5.14.14"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"5.10","versionEndExcluding":"5.15"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/0e32a2b85c7d92ece86c17dfef390c5ed79c6378"},{"url":"https://git.kernel.org/stable/c/0e309e1152fc34ef75991d9d69b165dbf75bf26c"},{"url":"https://git.kernel.org/stable/c/4afb912f439c4bc4e6a4f3e7547f2e69e354108f"}],"title":"btrfs: fix abort logic in btrfs_replace_file_extents","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-06-10T18:56:43.265826Z","id":"CVE-2021-47433","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-06-10T18:57:31.785Z"}},{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-04T05:39:59.455Z"},"title":"CVE Program Container","references":[{"url":"https://git.kernel.org/stable/c/0e32a2b85c7d92ece86c17dfef390c5ed79c6378","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/0e309e1152fc34ef75991d9d69b165dbf75bf26c","tags":["x_transferred"]},{"url":"https://git.kernel.org/stable/c/4afb912f439c4bc4e6a4f3e7547f2e69e354108f","tags":["x_transferred"]}]}]}}
