CVE-2022-28893

Published: 11 April 2022

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.

From the Ubuntu Security Team

Felix Fu discovered that the Sun RPC implementation in the Linux kernel did not properly handle socket states, leading to a use-after-free vulnerability. A remote attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code.
