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...
CVE-2026-97984 net: ipv6: Fix UDP length overflow with PMTU discover and big MTU
In the Linux kernel, the following vulnerability has been resolved: net: ipv6: Fix UDP length overflow with PMTU discover and big MTU This commit bounds cork-base.fragsize to IP6MAXMTU for UDP sockets to avoid a possible overflow of UDP length that triggers a WARN in udpsetlenshort when setsockop...
Astra Linux – Vulnerability in Linux, Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: inetdiag: fixed a kernel-infoleak issue for UDP sockets KMSAN reported a kernel-infoleak issue 1 that could be exploited by unprivileged users. After analysis, it turned out that UDP was not initializing r-idiagexpires. Other...
CVE-2026-68386
In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Reject unhashed UDP sockets on sockmap update UDP sockets get SOCKRCUFREE set when auto-bound. This means skisrefcountedunbound = true, while skisrefcountedbound = false. Because sockmap accepts unbound UDP sockets,...

CVE-2026-68386
The CVE concerns the Linux kernel’s BPF sockmap path. It describes a vulnerability where unhashed UDP sockets accepted by sockmap can have their refcount incremented via a BPF lookup, and if the socket becomes bound, the subsequent bpf_sk_release() may skip decreasing the refcount, leading to a m...
CVE-2026-68386: Undefined Security Weakness
In the Linux kernel, the following vulnerability has been resolved: bpf, sockmap: Reject unhashed UDP sockets on sockmap update UDP sockets get SOCKRCUFREE set when auto-bound. This means skisrefcountedunbound = true, while skisrefcountedbound = false. Because sockmap accepts unbound UDP sockets,...
Linux Distros Unpatched Vulnerability : CVE-2026-68386
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - bpf, sockmap: Reject unhashed UDP sockets on sockmap update UDP sockets get SOCKRCUFREE set when auto-bound. This means skisrefcountedunbound = true, while...
kernel: kernel: ipv6 frag escape
A flaw was found in the Linux kernel's ipv6 networking subsystem. An incorrect parameter length calculation allows an attacker with permissions to create UDP sockets to trigger overwrites of kernel memory, potentially leading to privilege escalation, data corruption, or a system crash...

kernel: geneve: Fix use-after-free in geneve_find_dev().
A use-after-free vulnerability exists in the Linux kernel. When devnet is dismantled, the geneveexitbatchrtnl function calls unregisternetdevicequeue for each device in the network namespace. Later, when the device is freed, it is still linked to the backend UDP socket in the network namespace...

SUSE CVE-2025-40080
In the Linux kernel, the following vulnerability has been resolved: nbd: restrict sockets to TCP and UDP Recently, syzbot started to abuse NBD with all kinds of sockets. Commit cf1b2326b734 "nbd: verify socket is supported during setup" made sure the socket supported a shutdown method. Explicitel...
FreeBSD -- SO_REUSEPORT_LB breaks connect(2) for UDP sockets
Problem Description: Connected sockets are not intended to belong to load-balancing groups. However, the kernel failed to check the connection state of sockets when adding them to load-balancing groups. Furthermore, when looking up the destination socket for an incoming packet, the kernel will...
