{"id":"CVE-2021-47519","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncan: m_can: m_can_read_fifo: fix memory leak in error branch\n\nIn m_can_read_fifo(), if the second call to m_can_fifo_read() fails,\nthe function jump to the out_fail label and returns without calling\nm_can_receive_skb(). This means that the skb previously allocated by\nalloc_can_skb() is not freed. In other terms, this is a memory leak.\n\nThis patch adds a goto label to destroy the skb if an error occurs.\n\nIssue was found with GCC -fanalyzer, please follow the link below for\ndetails.","modified":"2026-03-14T11:19:14.284341Z","published":"2024-05-24T15:15:13.783Z","references":[{"type":"FIX","url":"https://git.kernel.org/stable/c/31cb32a590d62b18f69a9a6d433f4e69c74fdd56"},{"type":"FIX","url":"https://git.kernel.org/stable/c/75a422165477dd12d2d20aa7c9ee7c9a281c9908"}],"affected":[{"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"5.15"},{"fixed":"5.15.8"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-47519.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"}]}
