CVE-2026-89513 RISC-V: KVM: Fix PMU event info array size overflow

In the Linux kernel, the following vulnerability has been resolved: RISC-V: KVM: Fix PMU event info array size overflow SBI PMU EVENTGETINFO stores guest-controlled numevents sizeofeinfo in a 32-bit integer. On RV64, numevents = 0x10000001 makes 0x100000010 truncate to 16. KVM then allocates one...

CVE-2026-89450

CVE-2026-89450 affects the Linux kernel's iommu/tegra241-cmdqv module. The function tegra241_vintf_init_vsid() programs a guest-provided virtual Stream ID (vSID) into the SID_MATCH register, whose VIRT_SID field spans only 20 bits (bits [20:1]). The existing bound check rejects only virt_sid >...

JLSEC-2026-1356 Wasmtime has a possible panic when lifting `flags` component value

Impact Wasmtime contains a possible panic which can happen when a flags-typed component model value is lifted with the Val type. If bits are set outside of the set of flags the component model specifies that these bits should be ignored but Wasmtime will panic when this value is lifted. This pani...

JLSEC-2026-1352 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...

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-2026-27204: Uncontrolled Resource Consumption

Wasmtime is a runtime for WebAssembly. Prior to versions 24.0.6, 36.0.6, 4.0.04, 41.0.4, and 42.0.0, 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...
