CVE-2014-0148

16
FAUCET Score

CVE-2014-0148 describes a denial-of-service vulnerability in Qemu versions prior to 2.0, specifically impacting its Hyper-V VHDX block driver. The flaw stems from missing bounds checks when calculating BAT entries, allowing a malicious actor to craft a disk image that triggers infinite loops and crashes the Qemu instance. Rated Medium severity (CVSS 5.5), this vulnerability requires local access to modify the Qemu disk image, leading to a high availability impact but no confidentiality or integrity compromise. There is no evidence of active exploitation, public exploit code, or significant community discussion surrounding this CVE.
