Description
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix a data-race around bpf_jit_limit.
While reading bpf_jit_limit, it can be changed concurrently via sysctl,
WRITE_ONCE() in __do_proc_doulongvec_minmax(). The size of bpf_jit_limit
is long, so we need to add a paired READ_ONCE() to avoid load-tearing.
Affected configurations
• linux linux kernel (>= 4.9.190 < 4.10)
• linux linux kernel (>= 4.14.140 < 4.15)
• linux linux kernel (>= 4.19.47 < 5.19.8)
• linux linux kernel 6.0
