CVE-2024-26607

Local crash via premature DRM bridge registration

Published Feb 29, 2024 · Updated May 11, 2026

A null-pointer dereference in the Linux sii902x DRM bridge driver allows local users to crash affected TI platforms during device probing. The driver registers the bridge before sii902x_init finishes I2C setup, allowing a deferred tidss probe to call sii902x_bridge_get_edid through an uninitialized I2C pointer. The race requires a TI platform using an sii9022 bridge, and a successful trigger crashes the kernel without reported data disclosure or modification.
