Astra Linux – Vulnerability in Linux, Linux 5.10

There is a use-after-free vulnerability in the ALSA PCM package within the Linux kernel. The SNDRVCTLIOCTLELEMREAD|WRITE32 function lacks locks that could be exploited in a use-after-free situation, potentially leading to an escalation of privileges to gain ring0 access from the system user. We...
