This security update provides a functional equivalent of RHSA-2026:64775. The original Red Hat(R) advisory is available from the Red Hat web site at https://access.redhat.com/errata/RHSA-2026:64775.

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.

A security update for the SUSE Linux Enterprise 11 SP4 kernel addresses multiple vulnerabilities, including use-after-free bugs, race conditions, and improper handling of network protocols. The update fixes 10 distinct CVEs affecting components such as SCSI, TCP, bonding, ALSA, KVM, networking, and Bluetooth subsystems. These vulnerabilities could lead to memory corruption or unexpected behavior in kernel modules.

In the Linux kernel, the following vulnerability has been resolved: inet: RAW sockets using IPPROTO_RAW MUST drop incoming ICMP Yizhou Zhao reported that simply having one RAW socket on protocol IPPROTO_RAW (255) was dangerous. socket(AF_INET, SOCK_RAW, 255); A malicious incoming ICMP packet can set the protocol field to 255 and match this socket, leading to FNHE cache changes. inner = IP(src="192.168.2.1", dst="8.8.8.8", proto=255)/Raw("TEST") pkt = IP(src="192.168.1.1", dst="192.168.2.1")/ICMP(type=3, code=4, nexthopmtu=576)/inner "man 7 raw" states: A protocol of IPPROTO_RAW implies enabled IP_HDRINCL and is able to send any IP protocol that is specified in the passed header. Receiving of all IP protocols via IPPROTO_RAW is not possible using raw sockets. Make sure we drop these malicious packets.
