SUSE-SU-2026:23167-1 Security update for python-pyasn1

This update for python-pyasn1 fixes the following issues: - CVE-2026-59884: BER/CER/DER decoder denial of service via unbounded long-form tag IDs bsc1271464. - CVE-2026-59885: Quadratic complexity in OBJECT IDENTIFIER and RELATIVE-OID processing allows denial of service bsc1271465. -...

Important: python-pyasn1

Issue Overview: pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the BER decoder shared by the CER and DER codecs parses long-form tags by accumulating continuation octets without an upper bound on the tag ID size, allowing a crafted input to force construction of an arbitrarily larg...

CVE-2026-63550 MZ Automation libiec61850 Out-of-bounds Read

The MMS BER decoder contains a boundary-handling flaw in the processing of certain fields within confirmed-request messages. When a crafted BER-encoded element is received over an established MMS session TCP port 102, the decoder may advance its internal read position incorrectly, leading to a he...

CVE-2026-65421

CVE-2026-65421 affects the MMS BER decoder in the MMS/IEC 61850 stack (as noted in NVD and CVE lists). The flaw is an attacker-supplied length for fixed-width BER fields (boolean/integer) that is not validated, causing a read past the end of a heap buffer. This results in termination of the MMS s...

SUSE-SU-2026:23006-1 Security update for python-pyasn1

This update for python-pyasn1 fixes the following issues: This update for python-pyasn1 fixes the following issues: - CVE-2026-59884: BER/CER/DER decoder denial of service via unbounded long-form tag IDs bsc1271464. - CVE-2026-59885: quadratic complexity in OBJECT IDENTIFIER and RELATIVE-OID...

SUSE CVE-2026-64448

In the Linux kernel, the following vulnerability has been resolved: smb: client: restrict implied bcc0 exemption to responses without data area smb2checkmessage has a long-standing quirk that accepts a response whose calculated length is one byte larger than the bytes actually received "server ca...

CVE-2026-64448

Summary (CVE-2026-64448): The Linux kernel fix addresses a SMB2 negotiation bug in CIFS/NTLM handling. A long-standing quirk in smb2_check_message() unconditionally granted a +1 length exemption for responses, even when a data area was present. This could cause the decoder to read past the receiv...
