CVE-2026-98150

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter subsystem. A local user could trigger a Denial of Service DoS by providing an invalid processor identifier during per-CPU map operations on systems with non-contiguous CPU configurations. Due to improper validation of CPU flags, th...
