  3. CVE-2024-38566
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix verifier assumptions about socket->sk The verifier assumes that 'sk' field in 'struct socket' is valid and non-NULL when 'socket' pointer itself is trusted and non-NULL. That may not be the case when socket was just created and passed to LSM socket_accept hook. Fix this verifier assumption and adjust tests.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: bpf: corrige las suposiciones del verificador sobre socket->sk. El verificador asume que el campo 'sk' en 'struct socket' es válido y no NULL cuando el puntero 'socket' en sí es confiable y no NULL. Puede que ese no sea el caso cuando el socket se acaba de crear y se pasó al gancho LSM socket_accept. Corrija esta suposición del verificador y ajuste las pruebas.
