- Summary
- bpf: Fix UAF via mismatching bpf_prog/attachment RCU flavors
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix UAF via mismatching bpf_prog/attachment RCU flavors
Uprobes always use bpfprogrunarrayuprobe() under tasks-trace-RCU protection. But it is possible to attach a non-sleepable BPF program to a uprobe, and non-sleepable BPF programs are freed via normal RCU (see _bpfprogputnoref()). This leads to UAF of the bpf_prog because a normal RCU grace period does not imply a tasks-trace-RCU grace period.
Fix it by explicitly waiting for a tasks-trace-RCU grace period after removing the attachment of a bpfprog to a perfevent.
