CVE-2026-3548 Buffer overflow in CRL number parsing in wolfSSL

Two buffer overflow vulnerabilities existed in the wolfSSL CRL parser when parsing CRL numbers: a heap-based buffer overflow could occur when improperly storing the CRL number as a hexadecimal string, and a stack-based overflow for sufficiently sized CRL numbers. With appropriately crafted CRLs,...

CVE-2026-3548

Two concrete vulnerabilities affect the wolfSSL CRL parser: heap-based and stack-based buffer overflows when parsing CRL numbers, triggered by crafted CRLs and only in builds with CRL support enabled. The issue stems from storing the CRL number as a hexadecimal string, enabling out-of-bounds writ...
