- Summary
- linux-raspi, linux-raspi-realtime, linux-xilinx 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)
