medium Tenable Cloud Security Plugin ID 461635

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: bpf: Check rcu_read_lock_trace_held()
 in bpf_map_lookup_percpu_elem() bpf_map_lookup_percpu_elem() helper is also available for sleepable bpf
 program. When BPF JIT is disabled or under 32-bit host, bpf_map_lookup_percpu_elem() will not be inlined.
 Using it in a sleepable bpf program will trigger the warning in bpf_map_lookup_percpu_elem(), because the
 bpf program only holds rcu_read_lock_trace lock. Therefore, add the missed check. (CVE-2025-38202)

Solution

Update the linux library and its related packages to version 6.1.147-1 or later.
