Astra Linux – Vulnerability in Linux, Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: ipack: ipoctal: fix module reference leak A reference to the carrier module was taken every time it was used, but it was only released once, when the final reference to the tty struct was removed. This issue was fixed by taking t...

CVE-2026-97964

A flaw was found in the Linux kernel's Point-to-Point Protocol PPP synchronous tty driver. When network packets are forwarded through PPP channel bridging, the driver prepends protocol header bytes to shared packet buffers without ensuring they are exclusively writable. This issue allows network...
