CVE-2026-98497: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: fix swapped IPv6 IPsec policy masks IPv6 XFRM policies may use different source and destination prefix lengths. mlx5eipsecpolicymask builds the corresponding masks independently, but setupfteaddr6 installs each mask in...

PT-2026-116751

In the Linux kernel, the following vulnerability has been resolved: ipv6: do not let ipv6 find hdr return an offset past the packet end ipv6 find hdr walks the extension header chain, skipping each header by the length that header itself declares. ipv6 optlen returns up to 2048, and the skip is...

PT-2026-116792

In the Linux kernel, the following vulnerability has been resolved: net: skbuff: fix pull-bound underflow in skb checksum setup ipv6 skb maybe pull tail subtracts skb headlenskb from the unsigned max argument and passes the result to pskb pull tail as a signed int. The function does not ensure th...

PT-2026-116822

In the Linux kernel, the following vulnerability has been resolved: ovpn: replace bind when clearing stale local source The UDP output fallback clears bind-local in place when the remembered source address is no longer usable. The bind is RCU-published and read locklessly by concurrent TX, so an...

PT-2026-117165

Name of the Vulnerable Software and Affected Versions BIRD Internet Routing Daemon affected versions not specified Description An IPv6 FlowSpec validation bypass allows an established BGP peer to inject FlowSpec rules matching destinations outside the authorized address space. This occurs because...

PT-2026-116814

In the Linux kernel, the following vulnerability has been resolved: udp: remove a disconnected socket from the 4-tuple hash table A UDP socket bound to a specific address and port keeps its entry in the 4-tuple hash table after it is disconnected: sk binds to 127.0.0.1:21001 sk connects to...

PT-2026-116815

In the Linux kernel, the following vulnerability has been resolved: ipv6: Fix dst leak for uncached routes. ip6 route output flags, ip6 rt put flags, and ip6 dst check detect an uncached route by list empty&rt-dst.rt uncached, which replaced the static DST NOCACHE flag check in commit a4c2fd7f789...

Linux Distros Unpatched Vulnerability : CVE-2026-98570

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - net: ipv6: keep room for the mac header in dstdevoverhead The seg6, ioam6 and rpl lwtunnels size their skbcowhead request as the length they are about to push...

Linux Distros Unpatched Vulnerability : CVE-2026-98598

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - ipv6: Prevent rt6insertexception for dying fib6info. Before the cited commit, fib6nhflushexceptions always set from-exceptionbucketflushed = 1 under...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.11 contains security vulnerabilities. These vulnerabilities stem from a race condition in IPv6’s cached routing processing: when listdelinit is executed concurrently, listempty is incorrectly evaluated as true. This leads to the incorrect invocation of dstholdsafe, and...

Linux Kernel Security Vulnerabilities

There are security vulnerabilities in Linux kernels versions from 6.12.81 to 6.12.113, from 6.18.22 to 6.18.56, from 6.1.168 to 6.2, from 6.6.134 to 6.7, from 6.19.12 to 6.20, and 7.0. The vulnerability stems from incomplete detection of IPv6 extension headers in tunneled data packets. The system...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.13 contains a security vulnerability. This vulnerability arises from the fact that the UDP socket is disconnected from the quadruplet hash table, but the hash count remains retained. As a result, data packets are still processed through quadruplet lookups, which may lea...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.16 contains a security vulnerability. This vulnerability arises from the process of local endpoint learning, where peer-lock is updated in place by reading bind-local. Since the UDP TX field is read without locking, it may lead to address tearing during concurrent IPv6...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.16 contains security vulnerabilities. These vulnerabilities arise from modifying the bind file that is published via RCU while clearing expired local sources. When reading the path without locking, it is possible to observe torn IPv6 addresses, leading to address...

Linux Kernel Security Vulnerabilities

The Linux kernel version 2.6.12 has a security vulnerability. This vulnerability stems from the function rtmt6check, which allows the configuration of rtinfo-addrnr to 0 when the request address matches certain conditions. This bypasses the loop termination condition in the IP6TRTFSTNSTRICT path...

CVE-2026-102551

Improper verification of the source of a communication channel in the IPv6 Router Advertisement handler in Amazon FreeRTOS-Plus-TCP before V4.4.2 might allow a remote third-party to influence an endpoint's IPv6 default gateway, on-link prefix, and address configuration via a crafted Router...

CVE-2026-102551

Amazon FreeRTOS-Plus-TCP is vulnerable to improper verification of the source of a communication channel in its IPv6 Router Advertisement handler prior to version V4.4.2 . A remote third-party could exploit this by sending a crafted Router Advertisement to influence an endpoint's IPv6 default gat...
