Linux Kernel Race Condition Vulnerability in pseries/papr-hvpipe Interrupt Handling

A race condition vulnerability has been identified in the Linux kernel's pseries/papr-hvpipe component. This issue arises when an interrupt is received on the same CPU while executing the ioctl or release handlers, potentially leading to a deadlock. The vulnerability affects several versions of the Linux kernel.

Impact

The vulnerability can cause a deadlock situation, where the system becomes unresponsive due to two processes waiting on each other to release resources.

Remediation

Users can apply the patch available in the Linux kernel stable tree to address this vulnerability. The patched version can be downloaded from the Linux kernel Git repository.
