| CVE-2026-2646 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 8.1 High |
| A heap-buffer-overflow vulnerability exists in wolfSSL's wolfSSL_d2i_SSL_SESSION() function. When deserializing session data with SESSION_CERTS enabled, certificate and session id lengths are read from an untrusted input without bounds validation, allowing an attacker to overflow fixed-size buffers and corrupt heap memory. A maliciously crafted session would need to be loaded from an external source to trigger this vulnerability. Internal sessions were not vulnerable. | ||||
| CVE-2026-3548 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 9.8 Critical |
| 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, either of these out of bound writes could be triggered. Note this only affects builds that specifically enable CRL support, and the user would need to load a CRL from an untrusted source. | ||||

| CVE-2026-7031 | 1 Tenda | 2 F456, F456 Firmware | 2026-04-29 | 8.8 High |
| A vulnerability was detected in Tenda F456 1.0.0.5. This impacts the function fromSafeMacFilter of the file /goform/SafeMacFilter. The manipulation of the argument page results in buffer overflow. It is possible to launch the attack remotely. The exploit is now public and may be used. | ||||
| CVE-2026-7032 | 1 Tenda | 2 F456, F456 Firmware | 2026-04-29 | 8.8 High |
| A flaw has been found in Tenda F456 1.0.0.5. Affected is the function SafeEmailFilter of the file /goform/SafeEmailFilter. This manipulation of the argument page causes buffer overflow. The attack can be initiated remotely. The exploit has been published and may be used. | ||||
| CVE-2026-31614 | 1 Linux | 1 Linux Kernel | 2026-04-29 | 7.1 High |
| In the Linux kernel, the following vulnerability has been resolved: smb: client: fix off-by-8 bounds check in check_wsl_eas() The bounds check uses (u8 *)ea + nlen + 1 + vlen as the end of the EA name and value, but ea_data sits at offset sizeof(struct smb2_file_full_ea_info) = 8 from ea, not at offset 0. The strncmp() later reads ea->ea_data[0..nlen-1] and the value bytes follow at ea_data[nlen+1..nlen+vlen], so the actual end is ea->ea_data + nlen + 1 + vlen. Isn't pointer math fun? The earlier check (u8 *)ea > end - sizeof(*ea) only guarantees the 8-byte header is in bounds, but since the last EA is placed within 8 bytes of the end of the response, the name and value bytes are read past the end of iov. Fix this mess all up by using ea->ea_data as the base for the bounds check. An "untrusted" server can use this to leak up to 8 bytes of kernel heap into the EA name comparison and influence which WSL xattr the data is interpreted as. | ||||

| CVE-2026-4159 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 3.3 Low |
| 1-byte OOB heap read in wc_PKCS7_DecodeEnvelopedData via zero-length encrypted content. A vulnerability existed in wolfSSL 5.8.4 and earlier, where a 1-byte out-of-bounds heap read in wc_PKCS7_DecodeEnvelopedData could be triggered by a crafted CMS EnvelopedData message with zero-length encrypted content.

| CVE-2026-5772 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 5.3 Medium |
| A 1-byte stack buffer over-read was identified in the MatchDomainName function (src/internal.c) during wildcard hostname validation when the LEFT_MOST_WILDCARD_ONLY flag is active. If a wildcard * exhausts the entire hostname string, the function reads one byte past the buffer without a bounds check, which could cause a crash. | ||||
| CVE-2026-7218 | 1 Totolink | 2 N300rt, N300rt Firmware | 2026-04-29 | 7.2 High |
| A vulnerability was detected in Totolink N300RT 3.4.0-B20250430. The impacted element is the function is_cmd_string_valid of the file /boafrm/formWsc of the component libapmib.so. Performing a manipulation of the argument localPin results in buffer overflow. The attack is possible to be carried out remotely. The exploit is now public and may be used. | ||||
| CVE-2026-7219 | 1 Totolink | 2 N300rt, N300rt Firmware | 2026-04-29 | 7.2 High |
| A flaw has been found in Totolink N300RT 3.4.0-B20250430. This affects an unknown function of the file /boafrm/formIpQoS. Executing a manipulation of the argument entry_name can lead to buffer overflow. The attack may be performed from remote. The exploit has been published and may be used. | ||||
| CVE-2026-5295 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 8.0 High |
| A stack buffer overflow exists in wolfSSL's PKCS7 implementation in the wc_PKCS7_DecryptOri() 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 (oriOID[MAX_OID_SZ]) via XMEMCPY without first validating that the parsed OID length does not exceed MAX_OID_SZ. A crafted CMS EnvelopedData message with an ORI recipient containing an OID longer than 32 bytes triggers a stack buffer overflow. Exploitation requires the library to be built with --enable-pkcs7 (disabled by default) and the application to have registered an ORI decrypt callback via wc_PKCS7_SetOriDecryptCb(). | ||||
| CVE-2026-5392 | 1 Wolfssl | 1 Wolfssl | 2026-04-29 | 5.4 Medium |
| Heap out-of-bounds read in PKCS7 parsing. A crafted PKCS7 message can trigger an OOB read on the heap. The missing bounds check is in the indefinite-length end-of-content verification loop in PKCS7_VerifySignedData(). | ||||
