This leaks memory when BTT\ninitialization fails.\n\nCall free_arenas() from the affected error paths to release the\nallocations.\n\n[ as: commit message and log edits ]","modified":"2026-08-18T03:30:58.548080142Z","published":"2026-08-15T05:54:16.781Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72224.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0b63788093ff6ccfffe6e87de9e08aeeb406599c"},{"type":"WEB","url":"https://git.kernel.org/stable/c/1a6b6442a982d0ca5fb6a1a39b6f6dfd760eda57"},{"type":"WEB","url":"https://git.kernel.org/stable/c/52a7e7ece79c4b0f406149e19cd2b4b11a6c19e4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/5804e6a6912b5a1e47c821777d69191d69a3fe64"},{"type":"WEB","url":"https://git.kernel.org/stable/c/68c967e105d50f885e02b0dbdc9211fd5f84bdcd"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7e49684d90faa34ff6d5586be658e986d9d475ac"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9ab5293d9ac3f2c4232220e563d04701f5f44607"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f4ca396bdd60b4e0a665b2589bfc4ddbea9bda2b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/72xxx/CVE-2026-72224.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-72224"},{"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":"5212e11fde4d40fa627668b4f2222d20db488f71"},{"fixed":"9ab5293d9ac3f2c4232220e563d04701f5f44607"},{"fixed":"68c967e105d50f885e02b0dbdc9211fd5f84bdcd"},{"fixed":"0b63788093ff6ccfffe6e87de9e08aeeb406599c"},{"fixed":"5804e6a6912b5a1e47c821777d69191d69a3fe64"},{"fixed":"52a7e7ece79c4b0f406149e19cd2b4b11a6c19e4"},{"fixed":"f4ca396bdd60b4e0a665b2589bfc4ddbea9bda2b"},{"fixed":"7e49684d90faa34ff6d5586be658e986d9d475ac"},{"fixed":"1a6b6442a982d0ca5fb6a1a39b6f6dfd760eda57"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72224.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.2.0"},{"fixed":"5.10.261"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.212"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"6.1.178"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.2.0"},{"fixed":"6.6.145"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.7.0"},{"fixed":"6.12.97"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.13.0"},{"fixed":"6.18.40"}]},{"type":"ECOSYSTEM","events":[{"introduced":"6.19.0"},{"fixed":"7.1.5"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-72224.json"}}],"schema_version":"1.9.0"}
