CVE-2023-53184 Vulnerability Summary

CVE-2023-53184: In the Linux kernel, the following vulnerability has been resolved: arm64/sme: Set new vector length before reallocating As part of fixing the allocation of the buffer for SVE state when changing SME vector length we introduced an immediate reallocation of the SVE state, this is also done when changing the SVE vector length for consistency. Unfortunately this reallocation is done prior to writing the new vector length to the task struct, meaning the allocation is done with the old vector length and can lead to memory corruption due to an undersized buffer being used. Move the update of the vector length before the allocation to ensure that the new vector length is taken into account. For some reason this isn't triggering any problems when running tests on the arm64 fixes branch (even after repeated tries) but is triggering issues very often after merge into mainline.

Assessing the Risk of CVE-2023-53184

Access Complexity Graph

The exploitability of CVE-2023-53184 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-2023-53184

No exploitability data is available for CVE-2023-53184.

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-2023-53184, 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.
