linux: A flaw was found in the Linux Kernel in RDS (Reliable Datagram Sockets) protocol
CVE-2023-1078 is fixed in 20 products on 1 platform, first by ALAS2023-2023-132, released March 11, 2023. It is not reported as exploited. Patch Radar priority: High.
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.
