Astra Linux – Vulnerability in Linux 5.10, Linux

A flaw was discovered in the Linux kernel’s networking code. A use-after-free occurred in the way the schsfb enqueue function utilized the socket buffer SKB cb field after the same SKB had been enqueued and freed into a child qdisc. This flaw allows a local, unprivileged user to cause a system...

Astra Linux – Vulnerability in Mariadb 10.3

MariaDB Server before version 10.7 is vulnerable to Denial of Service attacks. In the file extra/mariabackup/dscompress.cc, when an error occurs pthreadcreate returns a non-zero value during the execution of the createworkerthreads method, the held lock is not released properly. This allows local...
