{"id":"CVE-2022-49212","summary":"mtd: rawnand: atmel: fix refcount issue in atmel_nand_controller_init","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nmtd: rawnand: atmel: fix refcount issue in atmel_nand_controller_init\n\nThe reference counting issue happens in several error handling paths\non a refcounted object \"nc-\u003edmac\". In these paths, the function simply\nreturns the error code, forgetting to balance the reference count of\n\"nc-\u003edmac\", increased earlier by dma_request_channel(), which may\ncause refcount leaks.\n\nFix it by decrementing the refcount of specific object in those error\npaths.","modified":"2026-04-11T12:43:43.760194Z","published":"2025-02-26T01:55:48.690Z","related":["SUSE-SU-2025:01983-1","SUSE-SU-2025:1027-1","SUSE-SU-2025:1176-1","SUSE-SU-2025:1183-1","SUSE-SU-2025:1194-1","SUSE-SU-2025:1241-1","SUSE-SU-2025:1263-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49212.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0856bf27057561f42b37df111603cf5a0d040294"},{"type":"WEB","url":"https://git.kernel.org/stable/c/8baea2b96fa90af8d0f937caf4cf2105ee094d93"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9843c9c98f26c6ad843260b19bfdaa2598f2ae1e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9b08d211db4c447eb1a07df65e45e0aa772e0fa6"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a3587259ae553e41d1ce8c7435351a5d6b299a11"},{"type":"WEB","url":"https://git.kernel.org/stable/c/f1694169f3674cdf7553aed06864254635679878"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fe0e2ce5c87e9c0b9485ff566362030aa55972cf"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fecbd4a317c95d73c849648c406bcf1b6a0ec1cf"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49212.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49212"},{"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":"f88fc122cc34c2545dec9562eaab121494e401ef"},{"fixed":"0856bf27057561f42b37df111603cf5a0d040294"},{"fixed":"9843c9c98f26c6ad843260b19bfdaa2598f2ae1e"},{"fixed":"9b08d211db4c447eb1a07df65e45e0aa772e0fa6"},{"fixed":"a3587259ae553e41d1ce8c7435351a5d6b299a11"},{"fixed":"fe0e2ce5c87e9c0b9485ff566362030aa55972cf"},{"fixed":"8baea2b96fa90af8d0f937caf4cf2105ee094d93"},{"fixed":"f1694169f3674cdf7553aed06864254635679878"},{"fixed":"fecbd4a317c95d73c849648c406bcf1b6a0ec1cf"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-49212.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"4.12.0"},{"fixed":"4.14.276"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.15.0"},{"fixed":"4.19.238"}]},{"type":"ECOSYSTEM","events":[{"introduced":"4.20.0"},{"fixed":"5.4.189"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.5.0"},{"fixed":"5.10.110"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.11.0"},{"fixed":"5.15.33"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.16.0"},{"fixed":"5.16.19"}]},{"type":"ECOSYSTEM","events":[{"introduced":"5.17.0"},{"fixed":"5.17.2"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2022-49212.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
