CVE-2026-53150

Kernel memory corruption via zero-length TEXT property

Published Jun 25, 2026 · Updated Jun 25, 2026

Integer underflow in the Linux kernel allows local users to corrupt kernel memory via a zero-length XDomain TEXT property. The tb_property_entry_valid() validator accepts a zero-length TEXT entry, then indexes length times four minus one to write a terminator before the allocation. Local low-privileged access is required, and the published impact is limited to service interruption with no data disclosure or modification.
