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: bpf: Use raw_spinlock_t in ringbuf The
function __bpf_ringbuf_reserve is invoked from a tracepoint, which disables preemption. Using spinlock_t
in this context can lead to a "sleep in atomic" warning in the RT variant. This issue is illustrated in
the example below: BUG: sleeping function called from invalid context at kernel/locking/spinlock_rt.c:48
in_atomic(): 1, irqs_disabled(): 0, non_block: 0, pid: 556208, name: test_progs preempt_count: 1,
