Name of the Vulnerable Software and Affected Versions
Linux Kernel (affected versions not specified)
Description
The issue is related to a flaw in the Linux Kernel's RDS protocol, specifically in the rds rm zerocopy callback() function. This function uses list entry() on the head of a list, causing a type confusion. A local user can trigger this issue with rds message put(), leading to
struct rds msg zcopy info *info pointing to something else that is potentially controlled by the local user. This results in an out of bounds access and a lock corruption. The flaw is associated with incorrect handling of a data block list.Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
