Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 461928

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: gro: don't merge zcopy skbs
 skb_gro_receive() can currently copy frags between the source and GRO skb, without checking the zerocopy
 status, and in particular the SKBFL_MANAGED_FRAG_REFS flag. When SKBFL_MANAGED_FRAG_REFS is set, the skb
 doesn't hold a reference on the pages in shinfo->frags. Appending those frags to another skb's frags
 without fixing up the page refcount can lead to UAF. When either the last skb in the GRO chain (the one we
 would append frags to) or the source skb is zerocopy, don't merge the skbs. (CVE-2026-46323)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
