CVE-2026-64527

The CVE-2026-64527 entry describes a Linux kernel issue in drm/hyperv where VMBus packet size is not validated in the receive callback. hyperv_receive_sub() dispatches on msg->vid_hdr.type without knowing the host-written length, leading to a potential read of stale data when copying from hv-&...

CVE-2026-64524

The CVE-2026-64524 issue affects the Linux kernel's DRM Hyper-V driver. A SYNTHVID_RESOLUTION_RESPONSE with resolution_count > 64 could bypass the bound check on the supported_resolution array, potentially leading to out-of-bounds behavior during parsing. The fix binds resolution_count to the ...

CVE-2026-3842 Qemu-kvm: hyperv/syndbg: missing mapped-length guard after cpu_physical_memory_map causes host oob write

A flaw was found in QEMU. This vulnerability allows a local attacker within a guest virtual machine to write data beyond its allocated memory. This occurs when cpuphysicalmemorymap returns a shorter length than expected, leading to an out-of-bounds write. Successful exploitation could result in...
