Description:
LiangBin has reported a security issue in Linux Security Modules (LSM), which may grant normal user processes escalated privileges.
The problem is that when loading the Capability LSM module as a loadable kernel module, all existing processes gain unintended capabilities granting them root privileges.
Solution:
Only use the Capability LSM module when compiled into the kernel.
Grant only trusted users access to affected systems.
Provided and/or discovered by:
LiangBin, Venustech.
Changelog:
