CVE-2026-53032

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description A NULL pointer dereference occurs in the map kptr match type() function when handling scalar registers. This happens because the function calls btf is kernel() before verifying the base type(). Since a scalar register stored in a kptr slot lacks BPF Type Format (BTF) data, accessing reg->btf leads to a NULL dereference.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
