| Sažetak |
In the Linux kernel, the following vulnerability has been resolved:
KVM: arm64: Fix uninitialized memcache pointer in user_mem_abort()
Commit fce886a60207 ("KVM: arm64: Plumb the pKVM MMU in KVM") made the
initialization of the local memcache variable in user_mem_abort()
conditional, leaving a codepath where it is used uninitialized via
kvm_pgtable_stage2_map().
This can fail on any path that requires a stage-2 allocation
without transition via a permission fault or dirty logging.
Fix this by making sure that memcache is always valid. |
