UBUNTU-CVE-2025-40143

In the Linux kernel, the following vulnerability has been resolved: bpf: dont report verifier bug for missing bpfsccvisit on speculative path Syzbot generated a program that triggers a verifierbug call in maybeexitscc. maybeexitscc assumes that, when called for a state with insnidx in some SCC,...

CVE-2025-40143

CVE-2025-40143 concerns the Linux kernel BPF verifier. Syzbot-generated input could trigger a verifier_bug() in maybe_exit_scc() when processing a state inside an SCC, under speculative execution paths. The root cause was an assumption that an existing bpf_scc_visit instance always accompanies a ...
