CVE-2021-3491 Linux kernel io_uring PROVIDE_BUFFERS MAX_RW_COUNT bypass

The iouring subsystem in the Linux kernel allowed the MAXRWCOUNT limit to be bypassed in the PROVIDEBUFFERS operation, which led to negative values being usedin memrw when reading /proc//mem. This could be used to create a heap overflow leading to arbitrary code execution in the kernel. It was...
