A flaw was found in the Linux kernel's implementation of Pressure Stall Information. While the feature is disabled by default, it could allow an attacker to crash the system or have other memory-corruption side effects.

Отчет
The Pressure Stall Subsystem (PSI) is disabled by default on Red Hat kernels, if the feature has not been explicitly enabled using a kernel boot time parameter of 'psi=1', the system is not affected.
