In the Linux kernel, the following vulnerability has been resolved: bpf: put bpflink's program when link is safe to be deallocated In general, BPF link's underlying BPF program should be considered to be reachable through attach hook - link - prog chain, and, pessimistically, we have to assume th...

kernel: rcu-tasks: Avoid pr_info() with spin lock in cblist_init_generic()

A locking violation was found in the Linux kernel RCU-tasks subsystem's callback list initialization. During system boot, the initialization code calls prinfo while holding the rtp-cbsgbllock spinlock, causing a potentially sleeping function to be called in atomic context, which results in kernel...
