CVE-2025-38352

Linux kernel versions prior to 6.1.153-1~deb11u1 Linux kernel versions prior to 5.10.244-1 Linux kernel (affected versions not specified)

The Linux kernel contains vulnerabilities that may lead to privilege escalation, denial of service, or information leaks. The vulnerabilities have been addressed in versions 6.1.153-1~deb11u1 and 5.10.244-1 for Debian 11 bullseye. Modules are now signed with an ephemeral key on all architectures, and the broken pktcdvd driver is disabled. The hyperv-daemons package is also provided on arm64.

Upgrade the Linux kernel to version 6.1.153-1~deb11u1 or later. Upgrade the Linux kernel to version 5.10.244-1 or later. Reboot the system after installing the update.
