{"id":"AZL-48051","summary":"CVE-2024-41080 affecting package kernel for versions less than 6.6.64.2-9","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nio_uring: fix possible deadlock in io_register_iowq_max_workers()\n\nThe io_register_iowq_max_workers() function calls io_put_sq_data(),\nwhich acquires the sqd-\u003elock without releasing the uring_lock.\nSimilar to the commit 009ad9f0c6ee (\"io_uring: drop ctx-\u003euring_lock\nbefore acquiring sqd-\u003elock\"), this can lead to a potential deadlock\nsituation.\n\nTo resolve this issue, the uring_lock is released before calling\nio_put_sq_data(), and then it is re-acquired after the function call.\n\nThis change ensures that the locks are acquired in the correct\norder, preventing the possibility of a deadlock.","modified":"2026-04-01T05:17:08.196644Z","published":"2024-07-29T15:15:15Z","upstream":["CVE-2024-41080"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-41080"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.64.2-9"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-48051.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"}]}
