CVE-2025-40319

The CVE-2025-40319 issue is a race in the Linux kernel’s BPF ring buffer handling. Specifically, a BPF program can queue irq_work via bpf_ringbuf_commit(), and if the ring buffer is freed before the work runs, the irq_work thread may access freed memory. The documented fix is to synchronize pendi...
