Echo: linux: security update to 6.1.162-1

high Tenable Cloud Security Plugin ID 462577

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: ksmbd: fix buffer validation by
 including null terminator size in EA length The smb2_set_ea function, which handles Extended Attributes
 (EA), was performing buffer validation checks that incorrectly omitted the size of the null terminating
 character (+1 byte) for EA Name. This patch fixes the issue by explicitly adding '+ 1' to EaNameLength
 where the null terminator is expected to be present in the buffer, ensuring the validation accurately
 reflects the total required buffer size. (CVE-2025-68806)

Solution

Update the linux library and its related packages to version 6.1.162-1 or later.
