Description OSIDB Bzimport 2026-08-15 06:10:32 UTC 
In the Linux kernel, the following vulnerability has been resolved:

KVM: arm64: account pKVM reclaim against the VM mm

Protected guest faults charge long term pins to the VM's mm. Teardown
can run later from file release, where current->mm may be unrelated.

Drop the charge from kvm->mm instead.
