LOWCVSS 1/10EPSS 0.12%

Last modified

CVE-2025-13912 is a low-severity vulnerability rated 1/10 on the CVSS scale. Multiple constant-time implementations in wolfSSL before version 5.8.4 may be transformed into non-constant-time binary by LLVM optimizations, which can potentially result in observable timing discrepancies and lead to information disclosure through timing side-channel attacks.. EPSS estimates a 0.12% chance of exploitation in the next 30 days.
