CVE-2026-53450 Coturn: IPv4-mapped 127.0.0.1 bypasses default loopback peer protection

Coturn is a free open source implementation of TURN and STUN Server. Prior to 4.13.0, coturn rejects loopback peers by default unless allow-loopback-peers is enabled, but the default loopback guard can be bypassed by using the IPv4-mapped IPv6 peer address ::ffff:127.0.0.1 in a TURN...

CVE-2026-59882

guzzlehttp/psr7 is a PSR-7 HTTP message library implementation in PHP. Prior to 2.12.3, Uri::assertValidHost does not reject URI host components containing authority delimiters, embedded ports, or malformed IPv6 brackets, allowing Uri::getHost to disagree with the URI authority used for security ...

kernel: tcp: fix potential race in tcp_v6_syn_recv_sock()

A flaw was found in the Linux kernel. A race condition exists in the TCP Transmission Control Protocol IPv6 Internet Protocol version 6 socket handling, specifically within the tcpv6synrecvsock function. This occurs because a child socket becomes visible in the TCP hash table before its...

kernel: netfilter: flowtable: strictly check for maximum number of actions

A flaw was found in the Netfilter flowtable component of the Linux kernel. This vulnerability occurs because the system does not strictly check the maximum number of hardware offload actions for IPv6, allowing it to process more actions than supported. This could potentially lead to system...

CVE-2026-53362

In the Linux kernel, the following vulnerability has been resolved: ipv6: account for fraggap on the paged allocation path In ip6appenddata, when the paged-allocation branch is taken MSGMORE / NETIFFSG / large fraglen, alloclen and pagedlen are computed as alloclen = fragheaderlen + transhdrlen;...

USN-8493-1: Linux kernel vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - RISC-V architecture; - Cryptographic API; - InfiniBand drivers; - IOMMU subsystem; - Network drivers; -...

USN-8491-1: Linux kernel (OEM) vulnerabilities

Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in the following subsystems: - ARM64 architecture; - x86 architecture; - Block layer subsystem; - Cryptographic API; - DMA engine subsystem; -...

kernel: netfilter: nft_inner: Fix IPv6 inner_thoff desync

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nftinner module. This vulnerability arises from an incorrect handling of IPv6 inner packet processing, where the transport header offset innerthoff becomes desynchronized from the Layer 4 protocol l4proto. A remot...

kernel: mptcp: fix slab-use-after-free in __inet_lookup_established

A flaw was found in the Linux kernel's Multipath TCP MPTCP implementation. Due to incorrect memory allocation for IPv6 subflow child sockets, a use-after-free vulnerability exists. A remote attacker could exploit this by triggering concurrent lookups in the kernel's hash table, potentially leadin...

RHEL 9 : kernel (RHSA-2026:34095)

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2026:34095 advisory. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: kernel: mptcp: fix slab-use-after-fre...

CVE-2026-7656

The IPv6 Neighbor Discovery handlers in subsys/net/ip/ipv6nbr.c handlerainput, handlensinput, handlenainput used an incorrect boolean expression that combined the RFC 4861 validity checks with the ICMPv6 code check using the wrong operator precedence: the form was length/hop/source/target checks ...

CVE-2026-49412

The CVE-2026-49412 issue affects FreeBSD’s IPv6_MSFILTER in the kernel: the handler drops a serializing lock to copy the source-filter list and later reacquires it, creating a window where another thread can free the multicast filter structure and leave a stale pointer. This use-after-free enable...

CVE-2026-53249

A flaw was found in the Linux kernel's IPv4 networking component. This vulnerability allows an unprivileged application to set specific IP options, namely Loose Source and Record Route LSRR and Strict Source and Record Route SSRR. By exploiting this, an attacker can force network packets to...

CVE-2026-53275

A flaw was found in the Linux kernel's IPv6 multicast mcast component. When processing Multicast Listener Discovery MLD queries, a pointer to the multicast group address is not correctly reloaded after certain packet manipulations. This can lead to a use-after-free vulnerability, potentially...

CVE-2026-53228

In the Linux kernel, the following vulnerability has been resolved: ipv6: sit: reload inner IPv6 header after GSO offloads ipip6tunnelxmit caches the inner IPv6 header pointer at function entry and continues using it after iptunnelhandleoffloads. For GSO skbs, iptunnelhandleoffloads calls...
