CVE-2026-74526

Not scored yetLast modified Aug 17, 2026

Description

In the Linux kernel, the following vulnerability has been resolved:

scsi: mpi3mr: Fix potential deadlock in mpi3mr_fault_uevent_emit

mpi3mr_fault_uevent_emit() runs from the fault watchdog and reset paths where host I/O may already be blocked. GFP_KERNEL allocations here, both the local kzalloc_obj() and the ones inside kobject_uevent_env() itself, can trigger reclaim that waits on that blocked I/O and deadlock.

Use memalloc_noio_save()/restore() to cover the whole call instead of just the local allocation.
