Description

This security bulletin contains information about 1 vulnerability.


1) Out-of-bounds read (CVE-ID: CVE-2026-59961)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: 8.8 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N]


The vulnerability allows a remote attacker to disclose sensitive information and cause a denial of service.

The vulnerability exists due to an out-of-bounds read caused by integer underflow in the SNMP request parser functions decode_oid(), decode_str(), and decode_ptr() when parsing a crafted SNMP request with an oversized ASN.1/BER length field. A remote attacker can send a specially crafted SNMP request to disclose sensitive information and cause a denial of service.

The OID or string field is parsed before the SNMP community string is checked, so no authentication is required.
