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: mm: slub: avoid wake up kswapd in
 set_track_prepare set_track_prepare() can incur lock recursion. The issue is that it is called from
 hrtimer_start_range_ns holding the per_cpu(hrtimer_bases)[n].lock, but when enabled
 CONFIG_DEBUG_OBJECTS_TIMERS, may wake up kswapd in set_track_prepare, and try to hold the
 per_cpu(hrtimer_bases)[n].lock. Avoid deadlock caused by implicitly waking up kswapd by passing in
 allocation flags, which do not contain __GFP_KSWAPD_RECLAIM in the debug_objects_fill_pool() case. Inside
 stack depot they are processed by gfp_nested_mask(). Since ___slab_alloc() has preemption disabled, we
 mask out __GFP_DIRECT_RECLAIM from the flags there. The oops looks something like: BUG: spinlock recursion
