CVE-2026-98273

The Linux kernel is vulnerable to a crash when using eBPF to probe CS CALL instructions within a function. The root cause is that kprobes (using INT3 as the underlying implementation) incorrectly assumes a CALL instruction is 5 bytes long, while a CS-prefixed CALL occupies 6 bytes. This leads to ...
