CVE-2023-1078 Memory corruption in Linux kernel

What is CVE-2023-1078?

CVE-2023-1078 is a high-severity memory corruption vulnerability in Linux kernel, published on 27 Mar 2023. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

A flaw was found in the Linux Kernel in RDS (Reliable Datagram Sockets) protocol. The rds_rm_zerocopy_callback() uses list_entry() on the head of a list causing a type confusion. Local user can trigger this with rds_message_put(). Type confusion leads to `struct rds_msg_zcopy_info *info` actually points to something else that is potentially controlled by local user. It is known how to trigger this, which causes an out of bounds access, and a lock corruption.

Weakness: CWE-843, CWE-787
