Amazon Linux 2023: CVE-2023-1078: Important priority package update for kernel

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.
An out-of-bounds memory access flaw was found in the Linux kernel's RDS (Reliable Datagram Sockets) protocol due to triggering rds_message_put(). This could allow a local user to crash the system or potentially escalate their privileges on the system.
