In the Linux kernel, the following vulnerability has been resolved: net: lan743x: Fix memleak issue when GSO enabled Always map the `skb` to the LS descriptor.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: lan743x: Se solucionó el problema de fuga de memoria con GSO habilitado. Siempre se asigna `skb` al descriptor LS. Anteriormente, skb se asignaba al descriptor EXT cuando el número de fragmentos era cero con GSO habilitado. Asignar skb al descriptor EXT impide su liberación, lo que provoca una fuga de memoria.
