A NULL pointer dereference vulnerability in the Linux kernel's BPF subsystem was fixed in the btf_var_show() function. The function btf_var_show() unconditionally calls btf_type_id_resolve(), which dereferences a NULL pointer in certain base BTF contexts, causing a kernel crash. This issue affects specific linux-hwe-edge kernel versions and was resolved by adding a check similar to btf_modifier_show().
