CVE-2026-23357 Vulnerability Summary

CVE-2026-23357: In the Linux kernel, the following vulnerability has been resolved: can: mcp251x: fix deadlock in error path of mcp251x_open The mcp251x_open() function call free_irq() in its error path with the mpc_lock mutex held. But if an interrupt already occurred the interrupt handler will be waiting for the mpc_lock and free_irq() will deadlock waiting for the handler to finish. This issue is similar to the one fixed in commit 7dd9c26bd6cf ("can: mcp251x: fix deadlock if an interrupt occurs during mcp251x_open") but for the error path. To solve this issue move the call to free_irq() after the lock is released. Setting `priv->force_quit = 1` beforehand ensure that the IRQ handler will exit right away once it acquired the lock.

Assessing the Risk of CVE-2026-23357

Access Complexity Graph

The exploitability of CVE-2026-23357 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-2026-23357

No exploitability data is available for CVE-2026-23357.

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-2026-23357, 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.
