SUSE CVE-2026-98044
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...
SUSE CVE-2026-98061
In the Linux kernel, the following vulnerability has been resolved: bpf: Reject tail calls directly from callback frames A tail call from a non-zero frame is modeled as a return from that frame. The verifier makes R0 unknown and calls preparefuncexit for the taken branch. When the current frame i...

CVE-2026-98061
The Linux kernel contains a vulnerability in the BPF verifier where tail calls made directly from synchronous callback frames trigger a verifier bug. The root cause is that prepare_func_exit() marks register R0 as precise for callbacks, but the tail-call path synthesizes R0 instead of deriving it...

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, ...
