Veracode Vulnerability DatabaseVERACODE:11520Out-Of-Bounds Read
EPSS
Percentile
92.0%
libvirt.so is vulnerable to an out-of-bounds read. An attacker will be able to cause a denial of service condition or read sensitive heap information using a crafted blkiotune query when a disk is hot-plugged to the live definition. The qemuDomainGetBlockIoTune function in qemu/qemu_driver.c computes an index into the array of disks for the live definition then use it as the index for the persistent definition. This does not necessarily result in the same length which would lead to the out-of-bounds read.
