Linux kernel denial-of-service vulnerability (CNVD-2021-60515)

Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. Linux kernel is vulnerable due to a null pointer dereference and OOPS flaw in arch/powerpc/perf/core-book3s.c. By sending a constructed perf record command, an authenticated local attacker can exploit th...
