CVE-2025-40176

In the Linux kernel, the following vulnerability has been resolved: tls: wait for pending async decryptions if tlsstrpmsghold fails Async decryption calls tlsstrpmsghold to create a clone of the input skb to hold references to the memory it uses. If we fail to allocate that clone, proceeding with...

CVE-2025-40159

CVE-2025-40159 applies to the Linux kernel’s XSK/XDP path. The issue arises from accepting clearly invalid userspace-provided xdp_desc values, allowing validation to pass under certain overflow conditions. Root cause: desc->len can reach values near U32_MAX, and desc->addr (u64) can interac...
