{"id":"AZL-57446","summary":"CVE-2025-26599 affecting package xorg-x11-server for versions less than 1.20.10-15","details":"An access to an uninitialized pointer flaw was found in X.Org and Xwayland. The function compCheckRedirect() may fail if it cannot allocate the backing pixmap. In that case, compRedirectWindow() will return a BadAlloc error without validating the window tree marked just before, which leaves the validated data partly initialized and the use of an uninitialized pointer later.","modified":"2026-04-01T05:19:08.272960Z","published":"2025-02-25T16:15:39Z","upstream":["CVE-2025-26599"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-26599"}],"affected":[{"package":{"name":"xorg-x11-server","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/xorg-x11-server"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.20.10-15"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-57446.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:H/I:H/A:H"}]}
