Summary
linux-azure-fde, linux-azure-fde-7.0 vulnerabilities
Details

It was discovered that some Arm processors could complete a broadcast translation lookaside buffer (TLB) invalidation before memory writes made through the invalidated translation were globally observed. A local attacker could possibly use this to write to memory after permission to do so had been revoked, bypassing memory protections or escalating privileges. (CVE-2025-10263)

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - Character device driver; - Networking core; - IPv6 networking; - Unix domain sockets; (CVE-2026-52938, CVE-2026-53325, CVE-2026-53361, CVE-2026-53362)
