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.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
