KVM: x86: Protect ioapic_write_indirect() from Spectre-v1/L1TF attacks
commit 670564559ca35b439c8d8861fc399451ddf95137 upstream.
This fixes a Spectre-v1/L1TF vulnerability in ioapic_write_indirect().
This function contains index computations based on the
(attacker-controlled) IOREGSEL register.
This patch depends on patch
"KVM: x86: Protect ioapic_read_indirect() from Spectre-v1/L1TF attacks".
Fixes: 70f93dae32ac ("KVM: Use temporary variable to shorten lines.")
