CVE-2023-54022 Vulnerability Summary

CVE-2023-54022: In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix potential memory leaks at error path for UMP open The allocation and initialization errors at alloc_midi_urbs() that is called at MIDI 2.0 / UMP device are supposed to be handled at the caller side by invoking free_midi_urbs(). However, free_midi_urbs() loops only for ep->num_urbs entries, and since ep->num_entries wasn't updated yet at the allocation / init error in alloc_midi_urbs(), this entry won't be released. The intention of free_midi_urbs() is to release the whole elements, so change the loop size to NUM_URBS to scan over all elements for fixing the missed releases. Also, the call of free_midi_urbs() is missing at snd_usb_midi_v2_open(). Although it'll be released later at reopen/close or disconnection, it's better to release immediately at the error path.

Assessing the Risk of CVE-2023-54022

Access Complexity Graph

The exploitability of CVE-2023-54022 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2023-54022

No exploitability data is available for CVE-2023-54022.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2023-54022, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
