CVE-2026-43082

Local availability loss via unterminated property arrays

Published May 6, 2026 · Updated May 6, 2026

Improper termination in the Linux Kernel txgbe driver allows local users to cause an unspecified availability loss. The txgbe_nodes definition allocates gpio_props, i2c_props, sfp_props, and phylink_props with no extra empty property_entry sentinel, so consumers can scan past each intended list. Exploitation requires local low-privilege access and a system using the WangXun txgbe network driver; the published impact is limited to availability.
