{"id":"CVE-2022-49912","summary":"btrfs: fix ulist leaks in error paths of qgroup self tests","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbtrfs: fix ulist leaks in error paths of qgroup self tests\n\nIn the test_no_shared_qgroup() and test_multiple_refs() qgroup self tests,\nif we fail to add the tree ref, remove the extent item or remove the\nextent ref, we are returning from the test function without freeing the\n\"old_roots\" ulist that was allocated by the previous calls to\nbtrfs_find_all_roots(). Fix that by calling ulist_free() before returning.","modified":"2026-04-02T08:28:02.837294Z","published":"2025-05-01T14:10:54.231Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49912.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0a0dead4ad1a2e2a9bdf133ef45111d7c8daef84"},{"type":"WEB","url":"https://git.kernel.org/stable/c/203204798831c35d855ecc6417d98267d2d2184b"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3f58283d83a588ff5da62fc150de19e798ed2ec2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5d1a47ebf84540e40b5b43fc21aef0d6c0f627d9"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d37de92b38932d40e4a251e876cc388f9aee5f42"},{"type":"WEB","url":"https://git.kernel.org/stable/c/d81370396025cf63a7a1b5f8bb25a3479203b2ca"},{"type":"WEB","url":"https://git.kernel.org/stable/c/da7003434bcab0ae9aba3f2c003e734cae093326"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f46ea5fa3320dca4fe0c0926b49a5f14cb85de62"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49912.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49912"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"442244c9633292a147ab2b29e7007a7c8a3909b2"},{"fixed":"d81370396025cf63a7a1b5f8bb25a3479203b2ca"},{"fixed":"3f58283d83a588ff5da62fc150de19e798ed2ec2"},{"fixed":"203204798831c35d855ecc6417d98267d2d2184b"},{"fixed":"5d1a47ebf84540e40b5b43fc21aef0d6c0f627d9"},{"fixed":"0a0dead4ad1a2e2a9bdf133ef45111d7c8daef84"},{"fixed":"f46ea5fa3320dca4fe0c0926b49a5f14cb85de62"},{"fixed":"da7003434bcab0ae9aba3f2c003e734cae093326"},{"fixed":"d37de92b38932d40e4a251e876cc388f9aee5f42"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-49912.json"}}],"schema_version":"1.7.5"}
