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...

openSUSE 16 Security Update : python-pyasn1 (openSUSE-SU-2026:21392-1)

The remote openSUSE 16 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21392-1 advisory. - CVE-2026-59884: BER/CER/DER decoder denial of service via unbounded long-form tag IDs bsc1271464. - CVE-2026-59885: quadratic complexity in...

pyasn1: Uncontrolled resource consumption when converting decoded REAL values

Impact The univ.Real type converted its mantissa, base, exponent value to a Python float using exact big-integer exponentiation. A BER/CER/DER-encoded REAL value only a few bytes long can carry a very large exponent, causing this computation to attempt to materialize an astronomically large...

GHSA-M4P7-R5RC-7G4J pyasn1 BER/CER/DER decoder denial of service via unbounded long-form tag IDs

Impact The BER decoder shared by the CER and DER codecs parses long-form tags by accumulating continuation octets in a loop with no upper bound on the size of the tag ID. A crafted input can force the decoder to build an arbitrarily large integer, with CPU cost growing quadratically in input size...

CVE-2026-59885

pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.4, the BER, CER, and DER decoders process OBJECT IDENTIFIER and RELATIVE-OID values in quadratic time relative to the number of arcs, so a small crafted payload containing an OID with many arcs consumes excessive CPU per decode call and c...

openCryptoki: openCryptoki: Information disclosure and Denial of Service via malformed BER-encoded cryptographic objects

A flaw was found in openCryptoki, a PKCS11 Cryptographic Token Interface Standard library. The BER/DER Basic Encoding Rules/Distinguished Encoding Rules decoding functions in the shared common library do not properly validate attacker-controlled length fields against actual buffer boundaries. Thi...
