In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix a data-race around bpfjitlimit.
While reading bpfjitlimit, it can be changed concurrently via sysctl, WRITEONCE() in _doprocdoulongvecminmax(). The size of bpfjitlimit is long, so we need to add a paired READONCE() to avoid load-tearing.
