Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: CT: Fix cleanup of CT before cleanup of TC ct rules CT cleanup assumes that all tc rules were deleted first. Therefore, it is possible to delete the CT shared resources e.g., draction and fwdaction, which are shared...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: Fixed the internal port memory leak. The flow rule can be split, and additional postact rules are added to the postact table. It’s possible to trigger a memory leak when the rule forwards packets from an internal port...

Astra Linux – Vulnerability in Linux 5.10, Linux

The “Use After Free” vulnerability in the Linux kernel’s traffic control index filter tcindex allows for privilege escalation. The imperfect hash area can be updated while packets are being processed, leading to a use-after-free when the ‘tcfextsexec’ function is called with a corrupted tcfext. A...
