A issue was discovered in the Linux kernel through version 6.0.9. In the file drivers/media/dvb-core/dvbnet.c, there is a race condition between .disconnect and dvbdeviceopen, which leads to a use-after-free situation...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: ASoC: SOF: Intel: hda: Fixed a potential buffer overflow issue caused by snprintf. The snprintf function returns the size of the string that would be filled if it exceeds the given buffer size. Therefore, using this value may lea...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15, Linux 6.1

Closing an event channel in the Linux kernel can lead to a deadlock. This occurs when the closure operation is performed in parallel with an unrelated Xen console action, and the handling of a Xen console interrupt occurs in a unprivileged guest. The closure of an event channel is triggered, for...
