kernel: inet: frags: strip GSO state from fragments before reassembly

A flaw was found in the Linux kernel's network fragment reassembly process. An unprivileged local user, or a guest in a virtualized environment, could craft specially formed IPv4 or IPv6 network fragments that incorrectly retain Generic Segmentation Offload GSO state after reassembly. This...

SUSE CVE-2026-98852

In the Linux kernel, the following vulnerability has been resolved: net: extend IPv6 exthdr detection of tunneled packets Commit c4336a07eb6b "net: correctly handle tunneled traffic on IPV6CSUM GSO fallback" split skbgsohasextensionhdr into mutually exclusive branches on skb-encapsulation. This d...

php: php: Access control bypass via partial IPv6 address comparison

A flaw was found in PHP. The access control check for Internet Protocol version 6 IPv6 addresses in the FastCGI implementation compares only the first 12 bytes of a 16-byte address instead of the complete address. An attacker on an adjacent network with an address sharing the first 96 bits with a...

Security Bulletin: IBM Guardium Data Protection is affected by multiple vulnerabilities (CVE-2026-50010, CVE-2026-44249, CVE-2026-45416)

Summary IBM Guardium Data Protection has addressed these vulnerabilities in an update. Vulnerability Details CVEID:CVE-2026-50010 DESCRIPTION: Netty is a network application framework for development of protocol servers and clients. Prior to versions 4.1.135.Final and 4.2.15.Final,...

proxy-addr: proxy-addr vulnerable to IP spoofing via IPv4-mapped IPv6 trust subnet

A flaw was found in proxy-addr. When an application defines trusted proxy subnets using IPv4-mapped IPv6 addresses with an improper prefix length, the subnet parser fails open and erroneously treats all incoming network addresses as trusted. A remote, unauthenticated attacker can exploit this...

kernel: inet: frags: strip GSO state from fragments before reassembly

A flaw was found in the Linux kernel's network fragment reassembly process. An unprivileged local user, or a guest in a virtualized environment, could craft specially formed IPv4 or IPv6 network fragments that incorrectly retain Generic Segmentation Offload GSO state after reassembly. This...

CVE-2026-89790

A flaw was found in the Linux kernel's IPv6 networking subsystem. A race condition can occur during IPv6 multipath route rebalancing, where a concurrent update can lead to a divide-by-zero error. This vulnerability can cause the kernel to crash, resulting in a Denial of Service DoS for the affect...

CVE-2026-89562

A flaw was found in the Linux kernel's IPv6 Generic Routing Encapsulation GRE subsystem. The kernel incorrectly calculates the hardware header length for Non-Broadcast Multiple Access NBMA tunnel interfaces by improperly accumulating the underlying device's header length. A local authenticated...

CVE-2026-93226

A flaw was found in the Linux kernel's IPv6 networking subsystem. A race condition occurs when reading route exception lists without proper synchronization against concurrent route updates. A local user can trigger this flaw by querying network routing tables during simultaneous route updates,...

CVE-2026-98604

A flaw was found in the Linux kernel's OpenVPN ovpn subsystem. A race condition exists where local network endpoint updates modify binding data without proper synchronization while outbound network traffic reads the address concurrently. A remote peer or concurrent network activity could trigger...

CVE-2026-98485

A flaw was found in the Linux kernel's netfilter subsystem. This flaw allows a remote attacker to cause a Denial of Service DoS by sending specially crafted IPv6 packets to an affected system. The issue occurs when an IPv6 routing header match rule is configured with zero addresses, causing the...

CVE-2026-98598

A flaw was found in the Linux kernel's IPv6 networking subsystem. A local attacker or network traffic triggering route exceptions while an IPv6 route is being removed can cause a circular reference leak. This failure to release resources prevents network devices from unregistering, resulting in...

CVE-2026-98596

A flaw was found in the Linux kernel's IPv6 networking subsystem. A race condition during network device unregistration can lead to improper reference counting of uncached routes. A local attacker could exploit this flaw to cause an internal resource leak, leading to memory exhaustion and a Denia...

CVE-2026-98573

A flaw was found in the Linux kernel. An integer underflow in the networking subsystem allows an attacker to trigger an out-of-bounds memory copy by sending specially crafted Internet Protocol version 6 IPv6 packets with extension headers. This vulnerability can lead to kernel memory corruption,...

CVE-2026-98570

A flaw was found in the Linux kernel's IPv6 networking subsystem. An unauthenticated remote attacker can cause a Denial of Service DoS by sending network traffic through an affected IPv6 tunnel interface. Due to insufficient buffer allocation when reconstructing packet headers, an unchecked...

Siemens SIMATIC S7-1500 TM MFP Improper Input Validation (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...

Siemens SIMATIC S7-1500 TM MFP Heap-based Buffer Overflow (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;...
