CVE-2026-39863
Kamailio is an open source implementation of a SIP Signaling Server. Prior to 6.1.1, 6.0.6, and 5.8.8, an out-of-bounds access in the core of Kamailio formerly OpenSER and SER allows remote attackers to cause a denial of service process crash via a specially crafted data packet sent over TCP. The...
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...
Eclipse Open9J: Denial of Service in JITServer via crafted TCP message
A flaw was found in Eclipse Open9J and JITServer. A remote attacker, without needing to authenticate, can send a specially crafted 32-byte TCP message to JITServer. This action can cause JITServer to crash, leading to a Denial of Service DoS for affected systems...

Twisted is an event-based framework for internet applications, supporting Python 2.7 and Python 3.5+. It includes modules for many different purposes, including the following: Security Fixes: A denial of service vulnerability exists in Twisted framework when handling DNS compression pointer chain...
CVE-2026-46015
A flaw was found in the Linux kernel's TCP networking subsystem. When an established network connection is migrated between listener sockets within the same SOREUSEPORT group, applications waiting for new connections may not be properly notified. This can cause poll, epollwait, and blocking accep...

kernel: netfilter: xt_tcpmss: check remaining length before reading optlen
A flaw was found in the Linux kernel, specifically within the netfilter: xttcpmss module. A remote attacker could exploit this vulnerability by sending a specially crafted TCP packet. The TCP option parser does not properly validate the remaining option length, which results in an out-of-bounds...
CVE-2026-45918
A flaw was found in the Linux kernel's handling of OpenVPN Open Virtual Private Network TCP Transmission Control Protocol connections. A race condition can occur when a userspace process closes a socket while a peer is in the kernel's release list. This can lead to a null pointer dereference when...
EUVD-2026-32236
In the Linux kernel, the following vulnerability has been resolved: eth: fbnic: Add validation for MTU changes Increasing the MTU beyond the HDS threshold causes the hardware to fragment packets across multiple buffers. If a single-buffer XDP program is attached, the driver will drop all multi-fr...
CVE-2026-46015
In the Linux kernel, the following vulnerability has been resolved: tcp: call skdataready after listener migration When inetcsklistenstop migrates an established child socket from a closing listener to another socket in the same SOREUSEPORT group, the target listener gets a new accept-queue entry...
PT-2026-43785
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A race condition exists in the OpenVPN implementation within the Linux kernel. When a peer is deleted due to keepalive expiration, it is moved to a release list for processing via the ov...
Linux kernel 安全漏洞
The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the failure of the tcp listener to call skdataready after migration, potentially causing poll/epo...
