CVE-2025-38591

CVE-2025-38591 affects the Linux kernel and is resolved by a patch in the BPF verifier. The issue involved a narrowing context access check in BPF, where a program attempted to read a pointer field (offset 169) in __sk_buff (field sk at offset 168). The verifier incorrectly allowed this “narrower...

CVE-2025-38566

CVE-2025-38566 concerns the Linux kernel where the NFS over TLS path could mishandle TLS alerts in tls_alert_recv() due to how the kTLS control messages and data are split between the control buffer and the payload. The fix reworks how sock_recvmsg() sets up control messages so that, if a TLS con...
