CVE-2026-93111

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description An issue exists in the BPF (Berkeley Packet Filter) subsystem where tracing multi trampolines are not marked as ftrace managed. This occurs because the tracing multi link fails to set the ftrace managed flag, which prevents the system from correctly releasing the tracing multi link when an fentry link is subsequently attached. This failure can lead to kernel warnings during the execution of bpf trampoline multi detach().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
