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.

Affected configurations

• linux linux kernel (>= 4.17 < 4.19.273) • linux linux kernel (>= 4.20 < 5.4.232) • linux linux kernel (>= 5.5 < 5.10.168) • linux linux kernel (>= 5.11 < 5.15.94) • linux linux kernel (>= 5.16 < 6.1.12)
