CVE-2024-53190

A deadlock condition exists in the Linux kernel. During the probe of rtl8192cu, the driver ends-up performing an refuse read procedure and the read_efuse() function calls read_efuse_byte() based on the efuse size.

Red Hat rates the impact of this vulnerability as Moderate because exploitation requires local access, such as physically attaching a malformed USB device or utilizing local USB gadget emulation privileges, limiting the blast radius to a denial of service. Under typical enterprise deployments, server environments do not load wireless drivers or expose USB ports to untrusted hardware. A failure during device probe can cause worker threads to hang indefinitely, rendering the system unresponsive or preventing clean reboots without compromising confidentiality or integrity.

The CVSS score(s) listed for this vulnerability do not reflect the associated product's status, and are included for informational purposes to better understand the severity of this vulnerability.

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
