[SECURITY] Fedora 44 Update: os-autoinst-5^20260601git6ee8da2-1.fc44

The OS-autoinst project aims at providing a means to run fully automated tests. Especially to run tests of basic and low-level operating system components such as bootloader, kernel, installer and upgrade, which can not easily and safely be tested with other automated testing frameworks. However,...

Astra Linux – Vulnerability in grub2

A vulnerability in the GRUB2 bootloader has been identified in the normal module. This flaw, a memory use-after-free issue, occurs because the normalexit command is not properly unregistered when its related module is unloaded. An attacker can exploit this condition by invoking the command after...

Astra Linux – Vulnerability in grub2

A vulnerability has been identified in the GRUB Grand Unified Bootloader component. This flaw occurs because the bootloader improperly handles string conversions when reading information from a USB device, allowing an attacker to exploit inconsistencies in the length values. A local attacker can...

Astra Linux – Vulnerability in grub2

A use-after-free vulnerability has been identified in the GNU GRUB Grand Unified Bootloader. The flaw occurs because the process that closes files improperly retains a memory pointer, leaving an invalid reference to a file system structure. An attacker could exploit this vulnerability to cause th...

Astra Linux – Vulnerability in grub2

A vulnerability has been identified in the GRUB2 bootloader’s network module, posing an immediate Denial of Service DoS risk. This flaw is a use-after-free issue, as the netsetvlan command is not properly unregistered when the network module is unloaded from memory. An attacker who can execute th...
