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

In the Linux kernel, the following vulnerability has been resolved: TCP: Timers for kernel sockets are properly terminated. We received various reports from syzbot that indicated that TCP timers would still fire even after the corresponding netns has been dismantled. Fortunately, Josef Bacik was...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

The IPv6 implementation in the Linux kernel before version 6.3 has a maxsize threshold in the net/ipv6/route.c file that can be easily exceeded. This can lead to a denial of service condition, where the network becomes unreachable, resulting in errors when IPv6 packets are sent through a raw sock...

CVE-2026-15924: Use After Free

Zephyr's TLS socket layer in subsys/net/lib/sockets/socketstls.c keeps a single process-global array, clientcache, of cached client sessions that is shared by every TLS socket context. The functions that mutate and read it — tlssessionsave, tlssessionget, tlssessioncachereset, and the settings...

CVE-2026-87859

morgan is an HTTP request logger middleware for Node.js. In versions before 1.12.1, its escapeLogField function does not escape the double quote character, which delimits the quoted fields of the Apache combined log format that morgan emits. An unauthenticated remote attacker who controls a value...

CVE-2026-89044

Netty versions 4.1.133.Final through 4.1.137.Final and 4.2.13.Final through 4.2.17.Final fail to properly validate the final transfer coding in the Transfer-Encoding header, allowing attackers to smuggle requests by using malformed encoding declarations. Attackers can split Transfer-Encoding...

CVE-2026-88924

A flaw was found in the admin backend of gvfs. The privileged gvfsd-admin daemon changes the ownership of newly created private D-Bus sockets by calling the link-following chown function on a pathname inside a user-controlled directory. A local attacker can exploit this via a Time-of-Check...

kernel: inet: RAW sockets using IPPROTO_RAW MUST drop incoming ICMP

A flaw was found in the Linux kernel's handling of RAW sockets using IPPROTORAW. A remote attacker could send a specially crafted ICMP Internet Control Message Protocol packet. This malicious packet could set the protocol field to 255, causing it to be processed by a RAW socket configured for...

CVE-2026-80925

In the Linux kernel, the following vulnerability has been resolved: vlan: fix skbunderpanic and races when toggling HW VLAN offload Toggling hardware VLAN TX offload NETIFFHWVLANCTAGTX or NETIFFHWVLANSTAGTX on a lower device invokes vlantransferfeatures, which dynamically changed...

kernel: tcp: call sk_data_ready() after listener migration

A flaw was found in the Linux kernel's TCP networking subsystem. When an established network connection is migrated between listener sockets within the same SOREUSEPORT group, applications waiting for new connections may not be properly notified. This can cause poll, epollwait, and blocking accep...
