CVE-2026-98064

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix NULL-ptr-deref when showing a void BTF type btfmodifiershow resolves the modifier and then calls btftypeopst-show unconditionally. For the void type typeid 0, BTFKINDUNKN kindops has no entry, so -show is NULL. A "const...

EUVD-2026-86716

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 ...

CVE-2026-98063

The Linux kernel contains a NULL pointer dereference vulnerability in the btf_var_show() function. The issue occurs because btf_var_show() unconditionally calls btf_type_id_resolve() , which dereferences btf->resolved_ids . This pointer is NULL for base BTF structures, such as the vmlinux BTF ...

CVE-2026-98064

The Linux kernel contains a NULL-pointer dereference vulnerability within the BPF subsystem. The issue occurs in btf_modifier_show() when it attempts to call the show() operation on a void type (type_id 0, BTF_KIND_UNKN). Because the kind_ops[] array lacks an entry for this type, the pointer is N...
