This can lead to very little useful info for\ndebugging.\n\nThis patch will:\n\n- Add extra info for error reporting\n  Including:\n  * logical bytenr\n  * num_bytes\n  * type\n  * action\n  * ref_mod\n\n- Replace the btrfs_debug() with btrfs_err()\n\n- Move the error reporting into run_one_delayed_ref()\n  This is to avoid use-after-free, the @node can be freed in the caller.\n\nThis error should only be triggered at most once.\n\nAs if run_one_delayed_ref() failed, we trigger the error message, then\ncausing the call chain to error out:\n\nbtrfs_run_delayed_refs()\n`- btrfs_run_delayed_refs()\n   `- btrfs_run_delayed_refs_for_head()\n      `- run_one_delayed_ref()\n\nAnd we will abort the current transaction in btrfs_run_delayed_refs().\nIf we have to run delayed refs for the abort transaction,\nrun_one_delayed_ref() will just cleanup the refs and do nothing, thus no\nnew error messages would be output."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["fs/btrfs/extent-tree.c"],"versions":[{"version":"79787eaab46121d4713ed03c8fc63b9ec3eaec76","lessThan":"18bd1c9c02e64a3567f90c83c2c8b855531c8098","status":"affected","versionType":"git"},{"version":"79787eaab46121d4713ed03c8fc63b9ec3eaec76","lessThan":"fdb4a70bb768d2a87890409597529ad81cb3de8a","status":"affected","versionType":"git"},{"version":"79787eaab46121d4713ed03c8fc63b9ec3eaec76","lessThan":"853ffa1511b058c79a4c9bb1407b3b20ce311792","status":"affected","versionType":"git"},{"version":"79787eaab46121d4713ed03c8fc63b9ec3eaec76","lessThan":"39f501d68ec1ed5cd5c66ac6ec2a7131c517bb92","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/extent-tree.c"],"versions":[{"version":"3.4","status":"affected"},{"version":"0","lessThan":"3.4","status":"unaffected","versionType":"semver"},{"version":"5.10.165","lessThanOrEqual":"5.10.*","status":"unaffected","versionType":"semver"},{"version":"5.15.90","lessThanOrEqual":"5.15.*","status":"unaffected","versionType":"semver"},{"version":"6.1.8","lessThanOrEqual":"6.1.*","status":"unaffected","versionType":"semver"},{"version":"6.2","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":"3.4","versionEndExcluding":"5.10.165"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.4","versionEndExcluding":"5.15.90"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.4","versionEndExcluding":"6.1.8"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"3.4","versionEndExcluding":"6.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/18bd1c9c02e64a3567f90c83c2c8b855531c8098"},{"url":"https://git.kernel.org/stable/c/fdb4a70bb768d2a87890409597529ad81cb3de8a"},{"url":"https://git.kernel.org/stable/c/853ffa1511b058c79a4c9bb1407b3b20ce311792"},{"url":"https://git.kernel.org/stable/c/39f501d68ec1ed5cd5c66ac6ec2a7131c517bb92"}],"title":"btrfs: always report error in run_one_delayed_ref()","x_generator":{"engine":"bippy-1.2.0"}},"adp":[{"metrics":[{"cvssV3_1":{"scope":"UNCHANGED","version":"3.1","baseScore":7.8,"attackVector":"LOCAL","baseSeverity":"HIGH","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","integrityImpact":"HIGH","userInteraction":"NONE","attackComplexity":"LOW","availabilityImpact":"HIGH","privilegesRequired":"LOW","confidentialityImpact":"HIGH"}},{"other":{"type":"ssvc","content":{"id":"CVE-2022-49761","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"total"}],"version":"2.0.3","timestamp":"2025-03-28T15:20:30.780085Z"}}}],"problemTypes":[{"descriptions":[{"lang":"en","type":"CWE","cweId":"CWE-416","description":"CWE-416 Use After Free"}]}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2025-03-28T15:21:57.235Z"}}]}}
