What to do
AI-suggested
Red Hat classifies this vulnerability as low risk and notes that exploitation is unlikely under normal circumstances. No specific mitigation actions are required beyond applying any forthcoming official patches when available. Monitor Red Hat advisories for updates and apply patches promptly once released. If a fix is not yet available, consider limiting unprivileged guest user capabilities as a precaution.
Description
A vulnerability in QEMU's usb_ep_get() function can cause an assertion failure leading to a denial of service by crashing the QEMU process. This flaw may be triggered by a malicious unprivileged guest user but is considered unlikely to be exploited under normal circumstances due to the inability of unprivileged users to craft USB Request Blocks (URBs).
