- Summary
- bpf: Fix a data-race around bpf_jit_limit.
- Details
-
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, WRITE_ONCE() in __doprocdoulongvecminmax(). The size of bpfjitlimit is long, so we need to add a paired READONCE() to avoid load-tearing.
