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...

The vulnerability of the Simcenter Femap simulation application, related to writing beyond the buffer boundaries in memory, allows a hacker to execute arbitrary code.

The vulnerability of the Simcenter Femap simulation application lies in the writing of data beyond the buffer boundaries in memory. Exploiting this vulnerability could allow an attacker to execute arbitrary code using a specially created Catia MODEL file...
