JLSEC-2026-1364 Wasmtime has out-of-bounds write or crash when transcoding component model strings

Impact Wasmtime's implementation of transcoding strings between components contains a bug where the return value of a guest component's realloc is not validated before the host attempts to write through the pointer. This enables a guest to cause the host to write arbitrary transcoded string bytes...

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...

vm2's bufferAllocLimit cap bypassed by Buffer.concat and Buffer.from arrayLike

Summary vm2 bufferAllocLimit cap bypassed by Buffer.concat and Buffer.from arrayLike The bufferAllocLimit option introduced in 3.11.0 GHSA-6785-pvv7-mvg7 caps host-side Buffer allocations driven by sandbox code, the way embedders opt into timeout. The cap wraps Buffer.alloc, Buffer.allocUnsafe,...

CVE-2026-64286

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM for arm64 architecture. The flushhypvcpu function, responsible for copying the host virtual CPU vCPU context, does not properly clear a specific internal pointer hyprunningvcpu. This oversight allows a host to provide a value...

CVE-2026-64269: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: RDMA/rtrs-srv: Bound RDMA-Write length to chunk size in rdmawritesg When the server answers an RTRS READ, rdmawritesg builds the source scatter/gather entry for the IBWRRDMAWRITE that returns data to the peer. Its length is taken...
