Linux kernel is the kernel used by the Linux Foundation’s open source operating system, Linux. Linux kernel 5.14-rc3 is vulnerable due to a type obfuscation flaw in eBPF program processing. By executing a carefully crafted eBPF program, an authenticated attacker could exploit this vulnerability to gain elevated privileges and execute arbitrary code in the kernel context.
