Title
Virtio-win: virtio-win: denial of service via unvalidated descriptor count in unmap request
Summary
A flaw was found in virtio-win. The `RhelDoUnMap()` function does not properly validate the number of descriptors provided by a user during an unmap request. A local user could exploit this input validation vulnerability by supplying an excessive number of descriptors, leading to a buffer overrun. This can cause a system crash, resulting in a Denial of Service (DoS).

CVE-2026-5164 (GCVE-0-2026-5164)
Vulnerability from cvelistv5 – Published: 2026-03-30 15:02 – Updated: 2026-04-28 14:45

Title
Virtio-win: virtio-win: denial of service via unvalidated descriptor count in unmap request
Summary
A flaw was found in virtio-win. The `RhelDoUnMap()` function does not properly validate the number of descriptors provided by a user during an unmap request. A local user could exploit this input validation vulnerability by supplying an excessive number of descriptors, leading to a buffer overrun. This can cause a system crash, resulting in a Denial of Service (DoS).
Severity
6.7 (Medium)

Exploitation: none
Automatable: no
