Kernel Memory Corruption via eBPF Buffer Overflow: How a Static Assert Saved the Day

A critical vulnerability in an eBPF helper function allowed potential out-of-bounds memory reads and writes in kernel context due to unvalidated buffer size assumptions in chunked memory comparisons. The fix introduces a compile-time static assertion that enforces alignment invariants, ensuring that any future change to buffer size constants will produce a build error rather than silently introducing kernel memory corruption. Because eBPF programs execute with kernel privileges, this class of bu
