Description

In the Linux kernel, the following vulnerability has been resolved: sched/membarrier: reduce the ability to hammer on sys_membarrier On some systems, sys_membarrier can be very expensive, causing overall slowdowns for everything. So put a lock on the path in order to serialize the accesses to prevent the ability for this to be called at too high of a frequency and saturate the machine.

Affected configurations

• linux linux kernel (>= 4.14.0 < 4.19.307) • linux linux kernel (>= 4.20.0 < 5.4.269) • linux linux kernel (>= 5.5.0 < 5.10.210) • linux linux kernel (>= 5.11.0 < 5.15.149) • linux linux kernel (>= 5.16.0 < 6.1.79) • linux linux kernel (>= 6.2.0 < 6.6.18) • linux linux kernel (>= 6.7.0 < 6.7.6)
