{"id":"DEBIAN-CVE-2022-49761","details":"In the Linux kernel, the following vulnerability has been resolved:  btrfs: always report error in run_one_delayed_ref()  Currently we have a btrfs_debug() for run_one_delayed_ref() failure, but if end users hit such problem, there will be no chance that btrfs_debug() is enabled.  This can lead to very little useful info for debugging.  This patch will:  - Add extra info for error reporting   Including:   * logical bytenr   * num_bytes   * type   * action   * ref_mod  - Replace the btrfs_debug() with btrfs_err()  - Move the error reporting into run_one_delayed_ref()   This is to avoid use-after-free, the @node can be freed in the caller.  This error should only be triggered at most once.  As if run_one_delayed_ref() failed, we trigger the error message, then causing the call chain to error out:  btrfs_run_delayed_refs() `- btrfs_run_delayed_refs()    `- btrfs_run_delayed_refs_for_head()       `- run_one_delayed_ref()  And we will abort the current transaction in btrfs_run_delayed_refs(). If we have to run delayed refs for the abort transaction, run_one_delayed_ref() will just cleanup the refs and do nothing, thus no new error messages would be output.","modified":"2026-09-01T16:05:33.449312728Z","published":"2025-03-27T17:15:41.407Z","upstream":["CVE-2022-49761"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-49761"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.8-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49761.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.8-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49761.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.1.8-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49761.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
