Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.17.0-rc4+

Description A sleep-in-atomic bug has been identified in the Linux kernel, caused by the genpd debug remove() function being called with a spinlock held. This issue occurs when a genpd with GENPD FLAG IRQ SAFE gets removed. The bug can lead to a crash, as evidenced by a call trace showing the dump backtrace and show stack functions being called.

Recommendations For Linux kernel versions prior to 5.17.0-rc4+, consider moving the genpd debug remove() function out of the locking mechanism to fix the problem. As a temporary workaround, avoid removing genpd with GENPD FLAG IRQ SAFE to minimize the risk of exploitation.
