kernel: ipv4: raw: reject IP_HDRINCL packets with ihl < 5

A flaw was found in the Linux kernel's handling of IPv4 raw sockets. An unprivileged attacker with CAPNETRAW capabilities can craft and inject a malformed IPv4 packet with an invalid Internet Header Length IHL. This can lead to an out-of-bounds memory access when the packet is processed by certai...

CVE-2026-80353

A flaw was found in Apache Tomcat. A local attacker can gain unauthorized access to Unix domain communication sockets due to a time-of-check to time-of-use TOCTOU race condition in the APR/Native connector. When the connector initializes a socket, a brief timing window exists before restrictive...

CVE-2026-80353 Apache Tomcat: TOCTOU when setting specific permissions for Unix Domain Sockets - Fix for CVE-2026-65183 did not address APR connector

Time-of-check time-of-use TOCTOU race condition vulnerability in Apache Tomcat when creating unix domain sockets for the APR/Native connector allows an unauthorised local user to access the unix domain socket. The fix for CVE-2026-65183 only addressed the NIO connector. It did not address the sam...

CVE-2026-80353

Apache Tomcat versions 9.0.47 through 9.0.122 are vulnerable to a Time-of-check time-of-use (TOCTOU) race condition (CWE-367) during the creation of Unix domain sockets for the APR/Native connector . This flaw allows an unauthorised local user to access the Unix domain socket. The issue persists ...

tomcat: tomcat: Unauthorized socket access via TOCTOU race condition

A flaw was found in Apache Tomcat. A local attacker can gain unauthorized access to Unix domain communication sockets due to a time-of-check to time-of-use TOCTOU race condition in the APR/Native connector. When the connector initializes a socket, a brief timing window exists before restrictive...

CVE-2026-98801

A flaw was found in the Linux kernel. A local user can cause a Denial of Service DoS or kernel memory corruption by manipulating socket memory reservation settings. Due to a lack of upper-bound validation and missing locking mechanisms when applied to User Datagram Protocol UDP sockets, integer...

Linux Kernel Security Vulnerabilities

The Linux kernel version 5.16 contains a security vulnerability. This vulnerability arises from the fact that SORESERVEMEM is not limited to TCP sockets, and no upper limit is set. This may lead to concurrent operations on UDP sockets damaging skforwardalloc and memcg accounting, or causing...

nfs-utils: Improper exception handling leads to vulnerabilities

The nfs-utils have a vulnerability in exception handling. This vulnerability stems from the fsidd daemon process in nfs-utils improperly processing inputs received from local domain sockets. The dependent program relies on assertion validation for command parameters. Local users can send malforme...

Astra Linux – Vulnerability in python-urllib3

The urllib3 library before version 1.24.2 in Python mishandles certain cases where the desired set of CA certificates differs from the CA certificates stored in the operating system’s store. As a result, SSL connections succeed in situations where a verification failure would be the correct...
