Title
netdevsim: fix a race issue related to the operation on bpf_bound_progs list
Summary
In the Linux kernel, the following vulnerability has been resolved: netdevsim: fix a race issue related to the operation on bpf_bound_progs list The netdevsim driver lacks a protection mechanism for operations on the bpf_bound_progs list. When the nsim_bpf_create_prog() performs list_add_tail, it is possible that nsim_bpf_destroy_prog() is simultaneously performs list_del. Concurrent operations on the list may lead to list corruption and trigger a kernel crash as follows: [ 417.290971] kernel BUG at lib/list_debug.c:62!
