| Doc Text | Qemu emulator built with the USB OHCI emulation support is vulnerable to a null pointer dereference issue. It could occur when OHCI transitions to a OHCI_USB_OPERATIONAL state, leading to creation of multiple eof timers. A privileged user inside guest could use this flaw to crash the Qemu process on the host, resulting in DoS. | |||

A privileged user inside guest could use this flaw to crash the Qemu process on the host, resulting in DoS. | A NULL pointer dereference flaw was found in the QEMU emulator built with USB OHCI emulation support. The flaw could occur when OHCI transitions to the OHCI_USB_OPERATIONAL state, leading to the creation of multiple EOF timers. A privileged user inside a guest could exploit this flaw to crash the QEMU process on the host (denial of service). | ||
