CVE-2015-8745

CVE-2015-8745 affects QEMU with VMXNET3 paravirtual NIC emulation. Issue: reading Interrupt Mask Registers (IMR) can crash the QEMU process when exploited by a privileged guest (CAP_SYS_RAWIO), causing DoS. Connected data confirms the crash is tied to IMR access, not a remote exploit, and multipl...

CVE-2015-8744

CVE-2015-8744 affects QEMU when built with a VMXNET3 paravirtual NIC; the issue arises from improper/layer-2 header handling for very small frames (less than 22 bytes), which could be exploited by a privileged guest to crash the QEMU process and cause DoS. Public details in Debian/related advisor...
