Description

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: Make ICC_*SGI*_EL1 undef in the absence of a vGICv3 On a system with a GICv3, if a guest hasn't been configured with GICv3 and that the host is not capable of GICv2 emulation, a write to any of the ICC_*SGI*_EL1 registers is trapped to EL2. We therefore try to emulate the SGI access, only to hit a NULL pointer as no private interrupt is allocated (no GIC, remember?). The obvious fix is to give the guest what it deserves, in the shape of a UNDEF exception.

Affected configurations

• linux linux kernel (< 5.10.225) • linux linux kernel (>= 5.11 < 5.15.166) • linux linux kernel (>= 5.16 < 6.1.107) • linux linux kernel (>= 6.2 < 6.6.48) • linux linux kernel (>= 6.7 < 6.10.7) • linux linux kernel 6.11
