In the Linux kernel, the following vulnerability has been resolved:
clk: microchip: fix potential UAF in auxdev release callback
Similar to commit 1c11289b34ab ("peci: cpu: Fix use-after-free in
adev_release()"), the auxiliary device is not torn down in the correct
order. If auxiliary_device_add() fails, the release callback will be
called twice, resulting in a UAF. Due to timing, the auxdev code in this
driver "took inspiration" from the aforementioned commit, and thus its
bugs too!
Moving auxiliary_device_uninit() to the unregister callback instead
avoids the issue.
