Multiple security vulnerabilities affecting the Linux kernel have been addressed in a security update. These include fixes for use-after-free, out-of-bounds reads, integer overflows, memory corruption, denial of service, and buffer overflow issues across various kernel subsystems such as fbcon, smb, drm/amdgpu, netfilter, accel/ivpu, and others. The update is applicable to SUSE and Red Hat Enterprise Linux distributions. The vendor has released official patches to remediate these vulnerabilities.
