Echo: linux: security update to 6.1.147-1

medium Tenable Self-Hosted Container Security Plugin ID 463623

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: tipc: fix refcount warning in
tipc_aead_encrypt syzbot reported a refcount warning [1] caused by calling get_net() on a network
namespace that is being destroyed (refcount=0). This happens when a TIPC discovery timer fires during
network namespace cleanup. The recently added get_net() call in commit e279024617134 ("net/tipc: fix slab-
use-after-free Read in tipc_aead_encrypt_done") attempts to hold a reference to the network namespace.
However, if the namespace is already being destroyed, its refcount might be zero, leading to the use-
after-free warning. Replace get_net() with maybe_get_net(), which safely checks if the refcount is non-
zero before incrementing it. If the namespace is being destroyed, return -ENODEV early, after releasing
the bearer reference. [1]: https://lore.kernel.org/all/[email protected]/T/#m12
