{"id":"CVE-2022-49791","summary":"io_uring: fix multishot accept request leaks","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nio_uring: fix multishot accept request leaks\n\nHaving REQ_F_POLLED set doesn't guarantee that the request is\nexecuted as a multishot from the polling path. Fortunately for us, if\nthe code thinks it's multishot issue when it's not, it can only ask to\nskip completion so leaking the request. Use issue_flags to mark\nmultipoll issues.","modified":"2026-08-12T03:51:08.905009767Z","published":"2025-05-01T14:09:23.010Z","database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49791.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/0e4626de856ef8f25ecd9c716e76d4f95ce95639"},{"type":"WEB","url":"https://git.kernel.org/stable/c/91482864768a874c4290ef93b84a78f4f1dac51b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/49xxx/CVE-2022-49791.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-49791"},{"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":"390ed29b5e425ba00da2b6113b74a14949f71b02"},{"fixed":"0e4626de856ef8f25ecd9c716e76d4f95ce95639"},{"fixed":"91482864768a874c4290ef93b84a78f4f1dac51b"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-49791.json"}},{"package":{"name":"Kernel","ecosystem":"Linux"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"5.19.0"},{"fixed":"6.0.10"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-49791.json"}}],"schema_version":"1.9.0"}
