CVE-2022-28893 is a high-severity vulnerability (CVSS 7.8) in the SUNRPC subsystem of the Linux kernel (through version 5.17.2), affecting products like Debian and NetApp. It involves a use-after-free condition (CWE-416) where xs_xprt_free can be called before sockets are properly handled, potentially leading to high impact on confidentiality, integrity, and availability. While no active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion has been observed, its high severity warrants attention. It is not currently listed in CISA's KEV catalog.
