CVE-2026-98063

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix NULL-ptr-deref in btfvarshow btfvarshow calls btftypeidresolve unconditionally, which dereferences btf-resolvedids. That is NULL for a base BTF - e.g. the vmlinux BTF that bpfsnprintfbtf renders against - since base BTF ...
