Privilege Escalation

qemu:xenial is vulnerable to privilege escalation. The sdhcisdmatransfermultiblocks function in hw/sd/sdhci.c in QEMU aka Quick Emulator allows local OS guest privileged users to cause a denial of service infinite loop and QEMU process crash via vectors involving the transfer mode register during...

CVE-2020-25085

A flaw was found in QEMU. An out-of-bounds read/write access issue was found in the SDHCI Controller emulator of QEMU. It may occur while doing multi block SDMA, if transfer block size exceeds the 's-fifobuffers-bufmaxsz' size which would leave the current element pointer 's-datacount' pointing o...
