Multiple security vulnerabilities were identified in the Linux kernel's cryptographic API, SMB network file system, and io_uring subsystem. These flaws could potentially allow an attacker to compromise affected systems. The issues affect various versions of the linux-realtime-6.8 kernel and related packages. Official patches addressing these vulnerabilities have been released and are available through Ubuntu security updates. Users must update and reboot their systems to apply the fixes. Due to ABI changes, recompilation of third-party kernel modules is required after updating.
