Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: jbd2: fixed a potential use-after-free issue in jbd2fcwaitbufs. In jbd2fcwaitbufs, using bh after referencing the buffer’s head count may lead to a use-after-free. Therefore, ensure that the buffer is updated before referencing i...

Astra Linux – Vulnerability in glib2.0

A issue was discovered in GNOME GLib before versions 2.66.7 and 2.67.x before version 2.67.4. If the gbytearraynewtake function was called with a buffer of 4GB or more on a 64-bit platform, the length would be truncated modulo 2^32, resulting in unintended length truncation...
