In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: nv: Re-translate VNCR before injecting abort KVM faults in the VNCR page with FOLLWRITE whenever the guest aborts for a write, similar to how a regular stage-2 mapping is handled. It is entirely possible that the gues...

CVE-2026-72277 KVM: arm64: nv: Inject SEA if guest VNCR isn't normal memory

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: nv: Inject SEA if guest VNCR isn't normal memory When constructing an L1 VNCR mapping, KVM unconditionally uses cacheable memory attributes, even if the underlying PFN isn't memory. This gets particularly hairy if the...

CVE-2026-72277

Summary (CVE-2026-72277): In the Linux kernel’s KVM for arm64, the L1 VNCR mapping logic now rejects non-memory PFNs when constructing VNCR mappings, due to unconditional use of cacheable memory attributes that could trigger an SError on writeback. The vulnerability affected KVM’s handling of VNC...
