CVE-2016-9104

Status: ModifiedMedium (4.4)—

Multiple integer overflows in the (1) v9fs_xattr_read and (2) v9fs_xattr_write functions in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allow local guest OS administrators to cause a denial of service (QEMU process crash) via a crafted offset, which triggers an out-of-bounds access.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
