CVE-2026-46261 Vulnerability Summary
CVE-2026-46261: In the Linux kernel, the following vulnerability has been resolved: spi: wpcm-fiu: Fix potential NULL pointer dereference in wpcm_fiu_probe() platform_get_resource_byname() can return NULL, which would cause a crash when passed the pointer to resource_size(). Move the fiu->memory_size assignment after the error check for devm_ioremap_resource() to prevent the potential NULL pointer dereference.
Assessing the Risk of CVE-2026-46261
Access Complexity Graph
The exploitability of CVE-2026-46261 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-2026-46261
No exploitability data is available for CVE-2026-46261.
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-2026-46261, 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.
