CVE-2026-98044 bpf: Reject legacy packet loads from callbacks

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject legacy packet loads from callbacks checkldabs models a failed BPFLDABS or BPFLDIND in a subprogram as an implicit return with R0 set to zero. It calls preparefuncexit to explore this synthesized path. When the load is...

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, ...
