CVE-ID: CVE-2021-3592
CWE-ID:
CWE-763 - Release of invalid pointer or reference
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due to invalid pointer initialization within the bootp_input() function while processing UDP packets in the SLiRP networking implementation of QEMU. A malicious guest could use this flaw to leak 10 bytes of uninitialized heap memory from the host.
