Linux Distros Unpatched Vulnerability : CVE-2026-58216

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - An out-of-bounds read flaw was found in Samba's Kerberos Key Distribution Center's KDC password change kpasswd service. When processing malformed ASN.1-encoded...

UBUNTU-CVE-2026-58216

An authenticated user could possibly crash a KDC process. A kpasswd packet that contains malformed ASN.1 might cause the server to access 6 bytes of unallocated memory. This memory is not exposed to the user, but in some circumstances the server could crash...

PT-2026-65631

It was discovered that Samba's pam winbind incorrectly handled home directory ownership when mkhomedir was enabled. A local attacker could possibly use this issue to cause a denial of service by triggering a change in ownership of the root directory. CVE-2026-15779 Arjun Basnet, Douglas Bagnall,...

PT-2026-65627

An out-of-bounds read flaw was found in Samba's Kerberos Key Distribution Center's KDC password change kpasswd service. When processing malformed ASN.1-encoded Kerberos password change request, Samba server miscalculates the structure size and attempts to read up to six bytes beyond the end of th...

An authenticated user could possibly crash a KDC process

== Summary: A kpasswd packet that contains malformed ASN.1 might cause the server to access 6 bytes of unallocated memory. This memory is not exposed to the user, but in some circumstances the server could crash. Description A miscalculation means an ASN.1 structure used in a Kerberos password...

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...

CVE-2026-43820

NIOSSLCertificate.subjectAlternativeNames provides access to the raw bytes for a cert's SANs. NIOSSL provides access to a buffer assumed to be backed by an ASN1STRING, but not all SANs are backed by ASN1STRING, so accessing the buffer for such a type can lead to out-of-bounds memory access. This...

CVE-2026-59885

A flaw was found in pyasn1, a Python library for Abstract Syntax Notation One ASN.1. The BER, CER, and DER decoders process OBJECT IDENTIFIER and RELATIVE-OID values in quadratic time relative to the number of arcs. A remote attacker could exploit this by providing a specially crafted payload...
