CVE-2026-72283

CVE-2026-72283 concerns the Linux kernel's KVM/x86 path. The issue: when updating the IRTE for bypass fails, irqfd->producer is not cleared, creating a potential use-after-free if the irqfd is reachable via KVM routing while the producer is freed separately (e.g., VFIO PCI, where the producer ...

CVE-2026-72282

The CVE-2026-72282 entry concerns the Linux kernel KVM path: kvm_io_bus_get_dev() now requires the caller to hold the srcu lock, moving locking responsibilities to the caller. The function returns a device matched only by address, which can lead to a lifetime issue if the device’s type isn’t as e...

CVE-2026-72281

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...

CVE-2026-72281

The CVE-2026-72281 entry concerns the Linux kernel KVM arm64/pKVM reclaim against the VM memory manager. The issue arose because protected guest faults could pin long-term resources to the VM’s mm (memory descriptor), and teardown could execute later from file release with current->mm potentia...

CVE-2026-72279

The CVE-2026-72279 entry concerns the Linux kernel KVM arm64 implementation for the L1 VNCR mapping. The fix ensures that the host stage-1 mapping respects the read-only status of the guest PFN by caching PFN writability in the VNCR TLB and using this to constrain fixmap permissions. If a guest t...

CVE-2026-72280

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: nv: Drop bogus WARN for write to ZCREL2 It is entirely possible for a guest to write to the ZCREL2 sysreg alias while in a nested context, as it is expected if FEATNV2 is advertised to the L1 hypervisor.

CVE-2026-72280

CVE-2026-72280 concerns the Linux kernel KVM on arm64. The vulnerability arises from a logic issue where a guest could write to the ZCR_EL2 sysreg alias in a nested context if FEAT_NV2 is advertised to the L1 hypervisor. The fix is to drop the bogus WARN that could lead to a hyp_panic once hyp ve...
