CVE-2026-93044
A flaw was found in the Linux kernel's Berkeley Packet Filter BPF component. This vulnerability occurs when the BPF interpreter attempts to process specific arena-related instructions that it does not support, particularly when a BPF program uses an arena map. This can lead to a kernel bug and an...
