Astra Linux – Vulnerability in xwayland, xorg-server

A flaw was discovered in the X.Org X server. This vulnerability, an out-of-bounds read, affects the handling of XKB X Keyboard Extension modifier maps. An attacker with access to the X11 server can exploit this by sending a malformed request, causing the server to read beyond its intended memory...

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

In the Linux kernel, the following vulnerability has been resolved: nvme: Avoid double-free of special payloads. If a discard request needs to be retried, and that retry may fail before a new special payload is added, a double-free will occur. Clear the RQFSPECIALLOAD when the request is cleaned...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: mptcp: Use the appropriate destructor for IPv6. Previously, only the destructor from the TCP request sock in IPv4 was called, even if the subflow was IPv6. It is important to use the correct destructor to avoid memory leaks with...
