We can't use a mutex here as it\nwill lead to a deadlock.\n\nFix it by switching over to a spin lock.","modified":"2026-04-01T05:16:05.865309Z","published":"2024-09-04T19:15:30Z","upstream":["CVE-2024-44957"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-44957"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"5.15.200.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-48789.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"}]}
