high Tenable Self-Hosted Container Security Plugin ID 465051

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: net/sched: act_ife: Fix metalist
 update behavior Whenever an ife action replace changes the metalist, instead of replacing the old data on
 the metalist, the current ife code is appending the new metadata. Aside from being innapropriate behavior,
 this may lead to an unbounded addition of metadata to the metalist which might cause an out of bounds
 error when running the encode op: [ 138.423369][ C1]
