Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: net/sched: schhfsc: Fixed an issue where a division by zero could occur in rtscmin. The m2sm function converts a u32 slope into a u64 scaled value. For large inputs e.g., when m1=4000000000, the result can reach 2^32. The...
