Executive Summary

This vulnerability is an infinite loop issue in the coolsnowwolf lede project, specifically in the BN_mod_sqrt() function within the mt7603_wifi common modules. The function, cloned from OpenSSL, lacked a critical security patch that caused it to potentially enter an infinite loop during calculations when the modulus p is non-prime. This infinite loop means the program can get stuck and fail to complete its operations. [1]

Impact Analysis

The infinite loop vulnerability can lead to a denial of service (DoS) by causing the affected function to hang indefinitely during cryptographic calculations. This can disrupt normal operation of the device or software using the coolsnowwolf lede project, potentially leading to service outages or degraded performance. [1]

Mitigation Strategies

Apply the security patch that fixes the infinite loop vulnerability in the BN_mod_sqrt() function as described in the coolsnowwolf/lede project. This patch addresses the issue by incorporating the fix originally applied in OpenSSL, preventing the BN_mod_sqrt() function from entering an infinite loop during calculations. Updating to a version of lede that includes this patch or manually applying the patch will mitigate the vulnerability. [1]
