Echo: linux: security update to 6.1.133-1

medium Tenable Self-Hosted Container Security Plugin ID 464952

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: ice: fix memory leak in aRFS after
 reset Fix aRFS (accelerated Receive Flow Steering) structures memory leak by adding a checker to verify if
 aRFS memory is already allocated while configuring VSI. aRFS objects are allocated in two cases: - as part
 of VSI initialization (at probe), and - as part of reset handling However, VSI reconfiguration executed
 during reset involves memory allocation one more time, without prior releasing already allocated
 resources. This led to the memory leak with the following signature: [root@os-delivery ~]# cat
 /sys/kernel/debug/kmemleak unreferenced object 0xff3c1ca7252e6000 (size 8192): comm "kworker/0:0", pid 8,
