Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to the handling of CEQEs in the interrupt handler, which can cause the CPU core to stay in interrupt context too long and lead to soft lockup under heavy load. To resolve this, CEQEs are handled in the BH workqueue, and an upper limit is set for the number of CEQEs handled by a single call of the work handler.
