CVE-2021-4001 (GCVE-0-2021-4001)
Vulnerability from cvelistv5 – Published: 2022-01-21 00:00 – Updated: 2024-08-03 17:16
VLAI
EPSS
Summary
A race condition was found in the Linux kernel's ebpf verifier between bpf_map_update_elem and bpf_map_freeze due to a missing lock in kernel/bpf/syscall.c. In this flaw, a local user with a special privilege (cap_sys_admin or cap_bpf) can modify the frozen mapped address space. This flaw affects kernel versions prior to 5.16 rc2.
Severity
No CVSS data available.
