CVE-2023-54295 Vulnerability Summary

CVE-2023-54295: In the Linux kernel, the following vulnerability has been resolved: mtd: spi-nor: Fix shift-out-of-bounds in spi_nor_set_erase_type spi_nor_set_erase_type() was used either to set or to mask out an erase type. When we used it to mask out an erase type a shift-out-of-bounds was hit: UBSAN: shift-out-of-bounds in drivers/mtd/spi-nor/core.c:2237:24 shift exponent 4294967295 is too large for 32-bit type 'int' The setting of the size_{shift, mask} and of the opcode are unnecessary when the erase size is zero, as throughout the code just the erase size is considered to determine whether an erase type is supported or not. Setting the opcode to 0xFF was wrong too as nobody guarantees that 0xFF is an unused opcode. Thus when masking out an erase type, just set the erase size to zero. This will fix the shift-out-of-bounds. [ta: refine changes, new commit message, fix compilation error]

Assessing the Risk of CVE-2023-54295

Access Complexity Graph

The exploitability of CVE-2023-54295 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-2023-54295

No exploitability data is available for CVE-2023-54295.

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-2023-54295, 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.
