Descriptions

The SUNRPC subsystem in the Linux kernel through 5.17.2 can call xs_xprt_free before ensuring that sockets are in the intended state.

El subsistema SUNRPC en el kernel de Linux versiones hasta 5.17.2, puede llamar a xs_xprt_free antes de asegurarse de que los sockets están en el estado deseado

A use-after-free flaw was found in the Linux kernel’s net/sunrpc/xprt.c function in the Remote Procedure Call (SunRPC) protocol. This flaw allows a local attacker to crash the system, leading to a kernel information leak issue.
