The error most likely to happen is -ENOMEM, and we have a \ncomment mentioning that only -ENOMEM can happen, but that is not true, \nbecause in case qgroups are enabled any error returned from \nbtrfs_qgroup_trace_extent_post() (can be -EUCLEAN or anything returned \nfrom btrfs_search_slot() for example) can be propagated back to \nbtrfs_free_tree_block(). \n \nSo stop doing a BUG_ON() and return the error to the callers and make \nthem abort the transaction to prevent leaking space. Syzbot was \ntriggering this, likely due to memory allocation failure injection. \nSeverity: 0.0 | NA \nVisit the link for more details, such as CVSS details, affected products, timeline, and more...\",\n \"Detection Date\": \"04 Sep 2024\",\n \"Type\": \"Vulnerability\"\n}\n\ud83d\udd39 t.me/cvedetector \ud83d\udd39", "creation_timestamp": "2024-09-04T21:57:06.000000Z"} 2024-09-04T21:57:06+00:00 https://vulnerability.circl.lu/sighting/650f9da1-40a2-429c-9a5b-03a2de6df926/export 2026-06-05T10:24:15.562021+00:00 Alexandre Dulaunoy https://cve.circl.lu/user/adulau {"uuid": "650f9da1-40a2-429c-9a5b-03a2de6df926", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "c933734a-9be8-4142-889e-26e95c752803", "vulnerability": "CVE-2024-44963", "type": "seen", "source": "https://vulnerability.circl.lu/bundle/816dcc8e-f25a-4895-9b59-1bbd9caeccb8", "content": "", "creation_timestamp": "2025-12-03T14:14:49.267740Z"} 2025-12-03T14:14:49.267740+00:00 https://vulnerability.circl.lu/sighting/097ae0a5-382e-41b5-aaba-5d2ce8adb75b/export 2026-06-05T10:24:15.560038+00:00 Joseph Lee https://cve.circl.lu/user/syspect {"uuid": "097ae0a5-382e-41b5-aaba-5d2ce8adb75b", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2024-44963", "type": "seen", "source": "https://www.cert.ssi.gouv.fr/avis/CERTFR-2026-AVI-0316/", "content": "", "creation_timestamp": "2026-03-19T00:00:00.000000Z"} 2026-03-19T00:00:00+00:00
