CVE-2023-53320 Vulnerability Summary

CVE-2023-53320: In the Linux kernel, the following vulnerability has been resolved: scsi: mpi3mr: Fix issues in mpi3mr_get_all_tgt_info() The function mpi3mr_get_all_tgt_info() has four issues: 1) It calculates valid entry length in alltgt_info assuming the header part of the struct mpi3mr_device_map_info would equal to sizeof(u32). The correct size is sizeof(u64). 2) When it calculates the valid entry length kern_entrylen, it excludes one entry by subtracting 1 from num_devices. 3) It copies num_device by calling memcpy(). Substitution is enough. 4) It does not specify the calculated length to sg_copy_from_buffer(). Instead, it specifies the payload length which is larger than the alltgt_info size. It causes "BUG: KASAN: slab-out-of-bounds". Fix the issues by using the correct header size, removing the subtraction from num_devices, replacing the memcpy() with substitution and specifying the correct length to sg_copy_from_buffer().

Assessing the Risk of CVE-2023-53320

Access Complexity Graph

The exploitability of CVE-2023-53320 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-2023-53320

No exploitability data is available for CVE-2023-53320.

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-2023-53320, 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.
