linux, linux-hwe, linux-hwe-5.11, linux-hwe-5.4 vulnerability
No scoreFix available
Johan Almbladh discovered that the eBPF JIT implementation for IBM s390x systems in the Linux kernel miscompiled operations in some situations, allowing circumvention of the BPF verifier. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code.
