## Description
In the Linux kernel, the following vulnerability has been resolved:
bpf: Fix NULL-ptr-deref in btf\_var\_show()
btf\_var\_show() calls btf\_type\_id\_resolve() unconditionally, which
dereferences btf->resolved\_ids. That is NULL for a base BTF - e.g. the
vmlinux BTF that bpf\_snprintf\_btf() renders against - since base BTF is
not resolved during parsing. btf\_modifier\_show() guards this with
'if (btf->resolved\_ids)', but btf\_var\_show() does not.
A BPF program that passes the type\_id of a BTF\_KIND\_VAR from the vmlinux
BTF to bpf\_snprintf\_btf() thus NULL-derefs:
KASAN: probably user-memory-access in range [0x46638-0x4663f]
RIP: 0010:btf\_var\_show (kernel/bpf/btf.c:2929)
Call Trace:
btf\_type\_show (kernel/bpf/btf.c:8259)
btf\_type\_snprintf\_show (kernel/bpf/btf.c:8329)
bpf\_snprintf\_btf (kernel/trace/bpf\_trace.c:1047)
bpf\_prog\_test\_run\_raw\_tp (net/bpf/test\_run.c:829)
\_\_sys\_bpf (kernel/bpf/syscall.c:4804)
do\_syscall\_64 (arch/x86/entry/syscall\_64.c:84)
entry\_SYSCALL\_64\_after\_hwframe (arch/x86/entry/entry\_64.S:121)
Resolve the var's type directly with btf\_type\_skip\_modifiers() when
resolved\_ids is NULL, mirroring btf\_modifier\_show().
