Linux kernel is the kernel used by the Linux Foundation’s open source operating system Linux. kernel is one of the kernel-based virtual machines. Linux kernel is vulnerable to an information disclosure vulnerability caused by a pointer disclosure in the check_alu_op() function in Kernel/bpf/verifier.c. The vulnerability is caused by a pointer leak in the check_alu_op() function in Kernel/bpf/verifier.c. An attacker could exploit this vulnerability to obtain sensitive information.
