CVE-2026-99283

A flaw was found in the Linux kernel's Netfilter connection tracking subsystem. A remote attacker can cause a Denial of Service DoS by sending non-exact TCP reset RST packets to prematurely expire active connection tracking entries. When an in-window reset packet does not match the exact expected...

CVE-2026-122266

A flaw was found in aws-network-policy-agent. Due to improper isolation of shared connection tracking data, an authenticated attacker operating on the same host node can poison shared network tracking state using crafted raw network frames. An attacker can exploit this vulnerability to bypass...

CVE-2026-98077

A flaw was found in the Linux kernel's Session Initiation Protocol SIP netfilter connection tracking module. When processing incoming SIP headers, the parser fails to properly detect the end of the network packet buffer when trailing whitespace is present without a header delimiter, resulting in ...

CVE-2026-98873

A flaw was found in the Linux kernel's Netfilter connection tracking subsystem. Memory allocated for tracking expected network connections was not properly cleared upon allocation. A local user could exploit this vulnerability by querying connection tracking records via the Netlink interface,...

CVE-2026-98794

A flaw was found in the Linux kernel's IPVS IP Virtual Server subsystem. An attacker on the local network can send synchronization messages containing invalid connection flag combinations to an IPVS backup server. This lack of validation can disrupt connection tracking lookups and corrupt...

CVE-2026-98622

A flaw was found in the Linux kernel's traffic control connection tracking subsystem. Under normal load or during connection tracking flushes, expected memory allocation failures inappropriately trigger a kernel warning. A local user can exploit this condition by racing connection flushes against...

"The CentOS Linux 8.5 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS8.5:CLSA-2024:1711026811 advisory. - In the Linux kernel, the following vulnerability has been resolved: RDMA/cma: Ensure rdmaaddrcancel happens before issuing more...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/sched: actct: fix ref leak when switching zones When switching zones or network namespaces without performing a ct clear between them, a reference to the old ct entry is still leaked. This occurs because tcfctskbnfctcached...

CVE-2026-90237

A flaw was found in the Linux kernel's netfilter connection tracking nfct component. This vulnerability arises from the incorrect handling of connection tracking expectations, where early insertion of expectations into the list can lead to stale entries. These stale entries point to incorrect...

CVE-2026-97417

A flaw was found in the Linux kernel's netfilter connection tracking subsystem. The TCP option processing mechanism improperly assumes memory alignment when reading packet headers. A remote attacker could exploit this vulnerability by sending crafted TCP packets with misaligned SACK options throu...

Astra Linux – Vulnerability in Linux

In the Linux kernel, the following vulnerabilities have been resolved: netfilter: nftct: Skip the evaluation of rules for confirmed conntrack entries. The nftctexpectobjeval function calls nfctextadd for confirmed conntrack entries. However, nfctextadd can only be called when !nfctisconfirmed is...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: inet: inetdefrag: prevent sk release while still in use The functions iplocalout and others can pass skb-sk as a function argument. If the skb is a fragment and reassembly occurs before such a function call returns, the sk must n...

CVE-2026-89488

A flaw was found in the Linux kernel's Open vSwitch OVS component. An unprivileged user, operating from a user and network namespace, can trigger a use-after-free vulnerability during network namespace teardown. This occurs because packet processing attempts to use connection tracking CT limit...

UBUNTU-CVE-2026-89488

In the Linux kernel, the following vulnerability has been resolved: openvswitch: Fix CT limit teardown use-after-free Packet processing uses CT limit state under RCU, while netns teardown frees that state under ovsmutex. The CT limit pointer was neither removed from readers nor protected by a gra...

CVE-2026-89488 openvswitch: Fix CT limit teardown use-after-free

In the Linux kernel, the following vulnerability has been resolved: openvswitch: Fix CT limit teardown use-after-free Packet processing uses CT limit state under RCU, while netns teardown frees that state under ovsmutex. The CT limit pointer was neither removed from readers nor protected by a gra...

CVE-2026-89488

CVE-2026-89488 is a slab-use-after-free in the Linux kernel's Open vSwitch (OVS) component, occurring during network namespace teardown . Packet processing reads CT (connection tracking) limit state under RCU, while teardown frees that state under ovs_mutex without removing the pointer from reade...

CVE-2026-74347

A flaw was found in the Linux kernel's netfilter cttimeout component. This issue arises from the improper management of connection tracking timeout policies. When an iptables ruleset continues to reference a connection tracking timeout policy, new connection tracking entries can repeatedly attach...
