CVE-2023-1078

kernel: Heap OOB Write in rds_rm_zerocopy_callback()

Published Mar 27, 2023 CVSS 3.1 · 7.8 High EPSS < 1% KEV · Not listed
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.
