CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to a boundary error in the way the iSCSI Block driver handles a response coming from an iSCSI server while checking the status of a Logical Address Block (LBA) in an "iscsi_co_block_status()" routine. A remote authenticated attacker can trigger heap-based buffer overflow and cause a denial of service condition or potentially execute arbitrary code with privileges of the QEMU process on the host.
