Last modified

CVE-2026-46298 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
