Linux kernel resource management error vulnerability (CNVD-2022-69191)

Linux kernel is the kernel used by the Linux Foundation’s open source operating system Linux. Linux kernel 5.19.10 and earlier versions are vulnerable to a resource management error, which stems from a confusion in the directive in drivers/media/dvb-core/dmxdev.c that is responsible for freeing memory. An attacker could exploit this vulnerability to potentially cause program crashes, arbitrary code execution, etc.
