{"id":"DEBIAN-CVE-2024-50138","details":"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, expected: 0 RCU nest depth: 1, expected: 1 INFO: lockdep is turned off.
