RingBufferDetonator

Ring Buffer Detonator これは、rbpercpuempty におけるロジックバグを実証するための概念実証プログラムです。このバグを踏むと、プログラムは tracingreadpipe 内でカーネル空間のビジーデッドループにハングアップし、あらゆる UNIX シグナル（SIGKILL を含む）では停止または終了できなくなります。 Linux 4.5 で修正された seqbufused 計算のバグと同様の動作（デッドループ & CPU 消費）を示しますが、このプログラムは、まったく異なる原因を持ち、バージョン 3.10 から 5.14-rc1...

The vulnerability of the tracing_read_pipe() function in the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the tracingreadpipe function in the Linux operating system’s kernel is related to the lack of memory release after the effective lifespan of the function has ended. Exploiting this vulnerability can allow an attacker to cause a service failure...
