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-2025-40169

CVE-2025-40169 concerns the Linux kernel BPF verifier, where the check_alu_op() logic for ALU operations incorrectly allowed negative offsets due to signedness. The vulnerability arises when validating BPF instructions with signed 16-bit off fields; the historical check insn->off > 1 failed...

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 ...

CVE-2025-40123

CVE-2025-40123 is a Linux kernel vulnerability described in EulerOS advisory as a fix for the BPF tailcall compatibility check. The issue arises in the BPF subsystem where tailcalls could bypass constraints based on an program’s expected_attach_type, potentially enabling a NULL pointer dereferenc...
