Echo: linux: security update to 6.8.11-1

medium Tenable Self-Hosted Container Security Plugin ID 463111

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: hv_netvsc: Don't free decrypted memory
 In CoCo VMs it is possible for the untrusted host to cause set_memory_encrypted() or
 set_memory_decrypted() to fail such that an error is returned and the resulting memory is shared. Callers
 need to take care to handle these errors to avoid returning decrypted (shared) memory to the page
 allocator, which could lead to functional or security issues. The netvsc driver could free
 decrypted/shared pages if set_memory_decrypted() fails. Check the decrypted field in the gpadl to decide
 whether to free the memory. (CVE-2024-36911)

Solution

Update the linux library and its related packages to version 6.8.11-1 or later.
