  3. CVE-2024-26602
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.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: sched/membarrier: reduce la capacidad de martillar en sys_membarrier. En algunos sistemas, sys_membarrier puede ser muy costoso, provocando ralentizaciones generales en todo. Por lo tanto, bloquee la ruta para serializar los accesos y evitar que se llame a una frecuencia demasiado alta y sature la máquina.
