Linux Distros Unpatched Vulnerability : CVE-2026-53236

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - tcp: restrict SOATTACHFILTER to priv users This patch restricts the use of SOATTACHFILTER cBPF on TCP sockets to users with CAPNETADMIN capability. This blocks...

CVE-2026-53236

A flaw was found in the Linux kernel's handling of TCP sockets. An unprivileged application can exploit this vulnerability by attaching a Berkeley Packet Filter BPF using the SOATTACHFILTER option. This allows the application to conduct a side-channel attack, leading to the leakage of sensitive T...

PT-2026-52331

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A side-channel issue exists where an unprivileged application can attach a filter to TCP sockets to leak TCP sequence and acknowledgment numbers. This is achieved through the use of SO...

postgresql: PostgreSQL: Denial of Service via uncontrolled recursion in SSL/GSS negotiation

A flaw was found in PostgreSQL. Uncontrolled recursion during SSL Secure Sockets Layer and GSS Generic Security Service negotiation allows an attacker to achieve a sustained denial of service. This can be exploited by an attacker with access to a PostgreSQL AFUNIX socket. If SSL and GSS are both...
