Linux kernel is the kernel used by the Linux Foundation’s open source operating system Linux. Linux kernel is vulnerable due to a security flaw caused by an integer underflow in the legacy_parse_param function in fs/fs_context.c. By sending a carefully crafted request, a locally authenticated attacker could exploit the vulnerability to cause a buffer overflow and execute arbitrary code on the system with root privileges.
