Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackexpect: skip expectations in other netns via proc This resolves the issue where expectations related to other netnames are skipped when processing network traffic. Similar to the issue addressed in...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bpf: Scrubbing packets on bpfredirectpeer When bpfredirectpeer is used to redirect packets to a device in another network namespace, the packets are not scrubbed. This can lead to information about the packets being “misused” in...

Astra Linux – Vulnerability in Linux 5.15

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 in between, a reference to the old ct entry is still leaked. This occurs because tcfctskbnfctcached...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: netfilter: iptables: Fixed null-ptr-deref in iptablenattableinit. We received a report that iptables-restore sometimes triggered null-ptr-deref at boot time. 0 The problem is that iptablenattableinit is exposed to user space befo...

CVE-2026-68142

In the Linux kernel, the following vulnerability has been resolved: geneve: require CAPNETADMIN in the device netns for changelink A tunnel changelink operates on at most two netns, devnetdev and the sticky underlay netns geneve-net. They differ once the device is created in or moved to a netns...

EUVD-2026-55436

In the Linux kernel, the following vulnerability has been resolved: rds: drop incoming messages that cross network namespace boundaries rdsfindbound looks up the destination socket using a global rhashtable keyed solely on addr, port, scopeid. Network namespaces are not part of the key, so a send...

CVE-2026-68335 rds: drop incoming messages that cross network namespace boundaries

In the Linux kernel, the following vulnerability has been resolved: rds: drop incoming messages that cross network namespace boundaries rdsfindbound looks up the destination socket using a global rhashtable keyed solely on addr, port, scopeid. Network namespaces are not part of the key, so a send...

CVE-2026-68335

Summary: CVE-2026-68335 relates to the Linux kernel Reliable Datagram Sockets (RDS) vulnerability where an incoming message can be delivered to a socket across network namespace boundaries due to a global rhashtable key that omits netns. This can cause a use-after-free when the sender’s netns is ...

PT-2026-69735

Name of the Vulnerable Software and Affected Versions Linux kernel versions 3.8 and later affected versions not specified Description A use-after-free issue exists in the Reliable Datagram Sockets RDS implementation. The rds find bound function uses a global rhastable keyed by address, port, and...

kernel: rtnetlink: add missing netlink_ns_capable() check for peer netns

A flaw was found in the Linux kernel's rtnetlink component. An unprivileged local user, leveraging a user namespace, can exploit a missing CAPNETADMIN capability check in the rtnlnewlink function. This allows the user to create paired network devices in arbitrary network namespaces, including the...
