Missing required cryptographic step in the TLS 1.3 client HelloRetryRequest handshake logic in wolfSSL could lead to a compromise in the confidentiality of TLS-protected communications via a crafted HelloRetryRequest followed by a ServerHello message that omits the required keyshare extension,...
DEBIAN-CVE-2026-3549
Heap Overflow in TLS 1.3 ECH parsing. An integer underflow existed in ECH extension parsing logic when calculating a buffer length, which resulted in writing beyond the bounds of an allocated buffer. Note that in wolfSSL, ECH is off by default, and the ECH standard is still evolving...
DEBIAN-CVE-2026-3230
Missing required cryptographic step in the TLS 1.3 client HelloRetryRequest handshake logic in wolfSSL could lead to a compromise in the confidentiality of TLS-protected communications via a crafted HelloRetryRequest followed by a ServerHello message that omits the required keyshare extension,...
UBUNTU-CVE-2026-3547
Out-of-bounds read in ALPN parsing due to incomplete validation. wolfSSL 5.8.4 and earlier contained an out-of-bounds read in ALPN handling when built with ALPN enabled HAVEALPN / --enable-alpn. A crafted ALPN protocol list could trigger an out-of-bounds read, leading to a potential process crash...
UBUNTU-CVE-2026-4395
Heap-based buffer overflow in the KCAPI ECC code path of wceccimportx963ex in wolfSSL wolfcrypt allows a remote attacker to write attacker-controlled data past the bounds of the pubkeyraw buffer via a crafted oversized EC public key point. The WOLFSSLKCAPIECC code path copies the input to...

CVE-2026-3230 Improper key_share validation in TLS 1.3 HelloRetryRequest
Missing required cryptographic step in the TLS 1.3 client HelloRetryRequest handshake logic in wolfSSL could lead to a compromise in the confidentiality of TLS-protected communications via a crafted HelloRetryRequest followed by a ServerHello message that omits the required keyshare extension,...
CVE-2026-3230
wolfSSL’s TLS 1.3 client logic is affected by an improper key_share handling during HelloRetryRequest, allowing a crafted HelloRetryRequest followed by a ServerHello without the key_share extension to derive predictable traffic secrets from the (EC)DHE shared secret. Affected component: TLS hands...

CVE-2026-4395
CVE-2026-4395 affects wolfSSL wolfcrypt KCAPI ECC: a heap-based buffer overflow in wc_ecc_import_x963_ex() allows an attacker to write beyond the pubkey_raw buffer (132 bytes) when parsing a crafted oversized ECPoint in ServerKeyExchange. The path copies input to key->pubkey_raw via XMEMCPY wi...
CVE-2026-3547
Out-of-bounds read in ALPN parsing due to incomplete validation. wolfSSL 5.8.4 and earlier contained an out-of-bounds read in ALPN handling when built with ALPN enabled HAVEALPN / --enable-alpn. A crafted ALPN protocol list could trigger an out-of-bounds read, leading to a potential process crash...
CVE-2026-3547
CVE-2026-3547 concerns wolfSSL before or including version 5.8.4, where an out-of-bounds read can occur in ALPN parsing due to incomplete validation when ALPN is enabled (HAVE_ALPN / --enable-alpn). A crafted ALPN protocol list may trigger a crash, causing a denial of service. ALPN is disabled by...
