CVE-2022-49967 Information

Jun 19, 2025 cve

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.
