CVE Vulnerability Catalog

On Red Hat Enterprise Linux systems with xdg-user-dirs before 0.15.5, the system umask policy is not honored when creating XDG user directories because Xsession sources xdg-user-dirs.sh before setting umask. This may lead to incorrect directory permissions.

In FRRouting (FRR) up to version 7.3.1, when using the split-config feature, the init script creates an empty config file with world-readable default permissions, potentially leading to information leakage via frr.in and frrcommon.sh.in tools.

Vulnerability in the iscsi-initiator-utils package involves out-of-bounds write and information disclosure via unvalidated IPv6 payload length. Crafted ICMPv6 Echo requests can cause the iscsiuio daemon to trust an inflated ipv6_plen larger than the actual received payload.

A flaw was found in the libnbd library where a malicious actor could exploit a specially crafted URI to convince libnbd to open it. The vulnerability arises from the incorrect interpretation of non-standard hostnames starting with '-o' as arguments to the SSH process.

Improper handling of values in the microcode flow for some Intel(R) Processor Family may allow an escalation of privilege. A privileged user combined with a high complexity attack may enable this via local access.

Vulnerability in Intel processors allows exposure of sensitive information via shared microarchitectural predictor state during transient execution in VMX non-root (guest) operation. An unprivileged software adversary with an authenticated user can exploit this state to access data.

A TSIG packet with name compression can crash DNS. Incorrect size calculations when a TSIG record contains compressed names lead to a large out-of-bounds write, causing a server crash.

The iscsi-initiator-utils package version 6.2.1.11-0.git4b3e853.el10 has a stack buffer overflow vulnerability in idbm_recinfo_config. A malicious iSCSI target can inject an extra configuration line into a persisted node record via a crafted SendTargets TargetName, later causing a stack buffer overflow.

A low-privilege authenticated Samba AD user can modify internal LDB special DNs via LDAP access, enabling a domain takeover.

In NTFS-3G through version 2026.2.25, a heap buffer overflow exists in the ntfs_ib_cut_tail() function in libntfs-3g/index.c. This vulnerability allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by creating a file in a crafted directory.
