CVE-2026-74707

In the Linux kernel, the following vulnerability has been resolved: xsk: validate metadata when processing requests The zero-copy path validates TX metadata while obtaining the descriptor context, then reads it again later when preparing the hardware request. User space can change the metadata...

CVE-2026-74707

CVE-2026-74707 affects the Linux kernel AF_XDP zero-copy TX path. The root cause is a TOCTOU (time-of-check to time-of-use) race : TX metadata is validated when obtaining the descriptor context, but read again later when preparing the hardware request. User space can modify the metadata between t...
