Summary
linux-nvidia-6.8, linux-oracle, linux-oracle-6.8 vulnerabilities
Details

Jean-Claude Graf, Sandro Rüegge, Ali Hajiabadi, and Kaveh Razavi discovered that the Linux kernel contained insufficient branch predictor isolation between a guest and a userspace hypervisor for certain processors. This flaw is known as VMSCAPE. An attacker in a guest VM could possibly use this to expose sensitive information from the host OS. (CVE-2025-40300)

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: - HSI subsystem; - Bluetooth subsystem; - Timer subsystem; (CVE-2025-37838, CVE-2025-38118, CVE-2025-38352)
