CVE-2026-98151

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix REG INVARIANTS VIOLATION on speculative pointer arithmetic Take the following unprivileged program as an example: r0 = bpfmaplookupelem... / PTRTOMAPVALUE, offset 0 / ... 14: r0 += r1 / r1 is a bounded scalar / 15: r9 = ...

CVE-2026-98151

The Linux kernel contains a vulnerability in the BPF subsystem where a REG INVARIANTS VIOLATION occurs during speculative pointer arithmetic. The root cause is an inconsistency between var_off and the 32-bit range (r32) during the execution of sanitize_ptr_alu(). Specifically, the r32 register is...
