CVE-2022-50652

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.0.0-rc7

Description The Linux kernel contains a flaw in the 'uio dmem genirq' component related to interrupt handling. A missing unlock within the interrupt configuration process can lead to a sleep-in-atomic-context bug. This issue arises when a disable interrupt request is received while an interrupt is already disabled, preventing the spinlock from being unlocked. This can result in a kernel bug, potentially leading to system instability. The initial fix introduced a new issue, and a subsequent change to 'disable irq nosync()' aimed to avoid a deadlock between interrupt control and the handler.

Recommendations Update to a version newer than 6.0.0-rc7.
