Linux Distros Unpatched Vulnerability : CVE-2026-53148

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - thunderbolt: Clamp XDomain response data copy to allocation size tbxdppropertiesrequest derives the per-packet copy length from the response header without...

CVE-2026-53148

The CVE affects the Linux kernel Thunderbolt driver (tb_xdp_properties_request) where per-packet copy length is derived from the response header without bounds checking against the allocated data buffer, causing a potential out-of-bounds memcpy and memory corruption. The issue can lead to denial ...

In the Linux kernel, the following vulnerability has been resolved: ovpn: tcp - fix packet extraction from stream When processing TCP stream data in ovpntcprecv, we receive large cloned skbs from strprcv that may contain multiple coalesced packets. The current implementation has two bugs: 1. Head...

CVE-2026-22264

Suricata is a network IDS, IPS and NSM engine. Prior to version 8.0.3 and 7.0.14, an unsigned integer overflow can lead to a heap use-after-free condition when generating excessive amounts of alerts for a single packet. Versions 8.0.3 and 7.0.14 contain a patch. As a workaround, do not run...

CVE-2025-64330

A flaw was found in Suricata. This vulnerability allows a denial of service DoS via a single byte read heap overflow when logging the verdict in eve.alert and eve.drop records, requiring the per packet alert queue to be filled with alerts followed by a pass rule...

CVE-2025-64330 Suricata is vulnerable to a heap buffer overflow on verdict

Suricata is a network IDS, IPS and NSM engine developed by the OISF Open Information Security Foundation and the Suricata community. Prior to versions 7.0.13 and 8.0.2, a single byte read heap overflow when logging the verdict in eve.alert and eve.drop records can lead to crashes. This requires t...

unbound: Unbounded name compression could lead to Denial of Service

A flaw was found in Unbound which can lead to degraded performance and an eventual denial of service when handling replies with very large RRsets that require name compression to be applied. Versions prior to 1.21.1 do not have a hard limit on the number of name compression calculations that...
