Multiple security vulnerabilities affecting the SUSE Linux Enterprise 15 SP4 RT kernel were addressed in a security update. The update fixes a range of issues including Bluetooth event handling, IPv6 ICMP error processing, use-after-free conditions, stale data exposure, buffer overflows, locking issues, and memory management bugs. These vulnerabilities impact kernel components such as Bluetooth, networking, crypto, KVM virtualization, and filesystem handling. The update mitigates these issues to improve system stability and security.
