Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: gpio: virtuser: fix UAF in configfs release path The gpio-virtuser configfs release path uses a guard mutex to protect the device structure. However, the device is freed before the mutex cleanup runs, causing mutexunlock to opera...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: mfd: core: Added locking around ‘mfdofnodelist’. Manipulating a list in the kernel is not safe without some form of mutual exclusion mechanism. Add a mutex whenever we access or modify ‘mfdofnodelist’ to prevent potential crashes...
