Description OSIDB Bzimport 2025-05-08 07:02:06 UTC 
In the Linux kernel, the following vulnerability has been resolved:

net_sched: hfsc: Fix a potential UAF in hfsc_dequeue() too

Similarly to the previous patch, we need to safe guard hfsc_dequeue()
too. But for this one, we don't have a reliable reproducer.
