Name of the Vulnerable Software and Affected Versions
QEMU version 4.1.0
Description
The issue is related to a heap-based buffer over-read in the
iscsi aio ioctl cb function in the block/iscsi.c file. This may disclose unrelated information from process memory to an attacker. The vulnerability is associated with reading beyond the valid boundaries of a data buffer.Recommendations
For QEMU version 4.1.0, consider disabling the
iscsi aio ioctl cb function as a temporary workaround until a patch is available. Restrict access to the block/iscsi.c module to minimize the risk of exploitation. Avoid using the vulnerable iscsi aio ioctl cb function in the affected API endpoint until the issue is resolved. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Out of bounds Read
