CVE-2026-23417

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF component. This vulnerability occurs because the BPFST | BPFPROBEMEM32 immediate stores are not correctly handled by the constant blinding mechanism. As a result, user-controlled 32-bit immediate values can remain unblinded in...

CVE-2026-23417

CVE-2026-23417 affects the Linux kernel BPF component where PROBE_MEM32 immediate stores (BPF_ST|BPF_PROBE_MEM32) were not blinded by the JIT constant-blinding path. The root cause is that convert_ctx_accesses() rewrites BPF_ST|BPF_MEM to BPF_ST|BPF_PROBE_MEM32 during verification, but the blindi...
