CVE-2026-46298 Details
Description
In the Linux kernel, the following vulnerability has been resolved: pseries/papr-hvpipe: Fix race with interrupt handler While executing ->ioctl handler or ->release handler, if an interrupt fires on the same cpu, then we can enter into a deadlock. This patch fixes both these handlers to take spin_lock_irq{save|restore} versions of the lock to prevent this deadlock.
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.
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.
