CVE-2026-98044

The Linux kernel contains a vulnerability in the BPF verifier where legacy packet-load instructions (BPF_LD_ABS or BPF_LD_IND ) used within synchronous callbacks trigger a "callback unexpected regs" verifier bug. Because check_ld_abs() models failed loads as implicit returns with R0 set to zero, ...
