{"id":"AZL-31853","summary":"CVE-2023-1192 affecting package kernel for versions less than 5.15.137.1-1","details":"A use-after-free flaw was found in smb2_is_status_io_timeout() in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region, leading to a denial of service.","modified":"2026-04-01T05:10:26.431247Z","published":"2023-11-01T20:15:08Z","upstream":["CVE-2023-1192"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-1192"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.15.137.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-31853.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
