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: netlink: terminate outstanding dump on
socket close Netlink supports iterative dumping of data. It provides the families the following ops: -
start - (optional) kicks off the dumping process - dump - actual dump helper, keeps getting called until
it returns 0 - done - (optional) pairs with .start, can be used for cleanup The whole process is
asynchronous and the repeated calls to .dump don't actually happen in a tight loop, but rather are
triggered in response to recvmsg() on the socket. This gives the user full control over the dump, but also
means that the user can close the socket without getting to the end of the dump. To make sure .start is
always paired with .done we check if there is an ongoing dump before freeing the socket, and if so call
.done. The complication is that sockets can get freed from BH and .done is allowed to sleep. So we use a
workqueue to defer the call, when needed. Unfortunately this does not work correctly. What we defer is not
the cleanup but rather releasing a reference on the socket. We have no guarantee that we own the last
reference, if someone else holds the socket they may release it in BH and we're back to square one. The
whole dance, however, appears to be unnecessary. Only the user can interact with dumps, so we can clean up
when socket is closed. And close always happens in process context. Some async code may still access the
socket after close, queue notification skbs to it etc. but no dumps can start, end or otherwise make
progress. Delete the workqueue and flush the dump state directly from the release handler. Note that
further cleanup is possible in -next, for instance we now always call .done before releasing the main
module reference, so dump doesn't have to take a reference of its own. (CVE-2024-53140)

Solution

Update the sys-kernel/lakitu-kernel-5_15 library and its related packages to version 17800.372.84 or later.
