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.

In the Linux kernel, the following vulnerability has been resolved: ip6_vti: set netns_immutable on the fallback device. john1988 and Noam Rathaus reported that vti6_init_net() does not set the netns_immutable flag on the per-netns fallback tunnel device (ip6_vti0). Other similar tunnel drivers (like ip6_tunnel, sit, ip6_gre, and ip_tunnel) correctly set this flag during their fallback device initialization to prevent them from being moved to another network namespace.
