Echo: linux: security update to 6.1.176-1

high Tenable Self-Hosted Container Security Plugin ID 458614

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/rds: reset op_nents when zerocopy
 page pin fails When iov_iter_get_pages2() fails in rds_message_zcopy_from_user(), the pinned pages are
 released with put_page(), and rm->data.op_mmp_znotifier is cleared. But we fail to properly clear
 rm->data.op_nents. Later when rds_message_purge() is called from rds_sendmsg() the cleanup loop iterates
 over the incorrectly non zero number of op_nents and frees them again. Fix this by properly resetting
 op_nents when it should be in rds_message_zcopy_from_user(). (CVE-2026-43494)

Solution

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