A privileged user inside guest could use this flaw to crash the QEMU instance resulting in DoS. | ||||
| CVE-2016-2197 | 1 Qemu | 1 Qemu | 2025-04-12 | 5.5 Medium |
| QEMU (aka Quick Emulator) built with an IDE AHCI emulation support is vulnerable to a null pointer dereference flaw. It occurs while unmapping the Frame Information Structure (FIS) and Command List Block (CLB) entries.
