CVE-2025-37959

CVE-2025-37959 – Linux kernel : Vulnerability in bpf_redirect_peer where redirecting a packet to a device in another network namespace could leave skb metadata (namespace-bound state) from the host in the container namespace, enabling potential information leakage. The patch scrubs the packet on ...

CVE-2025-37948

CVE-2025-37948 affects the Linux kernel arm64 and is fixed by adding a BHB mitigation in the epilogue of BPF programs (cBPF) loaded via seccomp. The vulnerability arises when a classic cBPF program manipulates the branch history to influence speculative execution. The published details indicate t...
