CVE-2026-10047 Out-of-bounds write in Napoca real-mode hook handler via guest-controlled SS:SP (VA-13905)

The Bitdefender Napoca bare-metal hypervisor contains an out-of-bounds write vulnerability in the real-mode hook handler, implemented in napoca/kernel/handler.c. The handler uses a guest-controlled SS:SP-derived offset as an index into the 1MB RealModeMemory buffer without bounds validation. With...

CVE-2026-10047

The CVE-2026-10047 entry describes an out-of-bounds write in Bitdefender Napoca bare-metal hypervisor’s real-mode hook handler (napoca/kernel/handler.c). The vulnerability arises from using a guest-controlled SS:SP-derived offset as an index into the 1MB RealModeMemory buffer without bounds check...

GHSA-852M-CVVP-9P4W Wasmtime WASI implementations are vulnerable to guest-controlled resource exhaustion

Impact Wasmtime's implementation of WASI host interfaces are susceptible to guest-controlled resource exhaustion on the host. Wasmtime did not appropriately place limits on resource allocations requested by the guests. This serves as a Denial of Service vector where a guest can induce a range of...
