Описание
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. A privileged user inside guest could use this flaw to crash the QEMU process instance resulting in DoS.
A NULL pointer dereference flaw was found in the QEMU emulator built with IDE AHCI emulation support. The flaw occurs when unmapping the Frame Information Structure(FIS) & Command List Block(CLB) entries. A privileged user inside a guest could use this flaw to crash the QEMU process instance (denial of service).
