CVE-2023-1078 (GCVE-0-2023-1078)

Vulnerability from cvelistv5 – Published: 2023-03-27 00:00 – Updated: 2025-05-05 16:07
VLAI
Summary
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.

Type confusion leads to `struct rds_msg_zcopy_info *info` actually points to something else that is potentially controlled by local user.
