Kernel support for LLVM 23 unwind tables lets bpf_throw() run Drop glue before discarding frames that hold locks or referenced pointers.

McKenney and Desnoyers floated a full RFC series; Torvalds wants core conversions and real workload numbers, not torture tests.

On kernels without an MMU, pin and unpin refcounts were asymmetric, so repeated io_uring fixed-buffer registration could free pages still mapped by userspace.

The mail transfer agent closes four flaws dating to 2014, with no workaround short of upgrading.
