CVE-2026-34945

A flaw was found in Wasmtime's Winch compiler. This vulnerability, present in versions from 25.0.0 to before 36.0.7, 42.0.2, and 43.0.1, arises from an incorrect translation of the table.size instruction for 64-bit WebAssembly tables. An attacker, by crafting a malicious WebAssembly guest, could...

CVE-2026-5988 Tenda F451 AdvSetWrlsafeset formWrlsafeset stack-based overflow

A vulnerability was detected in Tenda F451 1.0.0.7. This impacts the function formWrlsafeset of the file /goform/AdvSetWrlsafeset. Performing a manipulation of the argument mitssid results in stack-based buffer overflow. The attack can be initiated remotely. The exploit is now public and may be...

CVE-2026-5295 Stack Buffer Overflow in wolfSSL PKCS7 wc_PKCS7_DecryptOri() via Oversized OID

A stack buffer overflow exists in wolfSSL's PKCS7 implementation in the wcPKCS7DecryptOri function in wolfcrypt/src/pkcs7.c. When processing a CMS EnvelopedData message containing an OtherRecipientInfo ORI recipient, the function copies an ASN.1-parsed OID into a fixed 32-byte stack buffer...

CVE-2026-5295

The CVE describes a stack buffer overflow in wolfSSL’s PKCS7 code (wc_PKCS7_DecryptOri() in wolfcrypt/src/pkcs7.c) when handling CMS EnvelopedData with an OtherRecipientInfo (ORI) recipient. A parsed OID longer than 32 bytes is copied into a fixed 32-byte stack buffer (oriOID[MAX_OID_SZ]) without...
