CVE-2024-44967

Local use-after-free via premature I2C cleanup

Published Sep 4, 2024 · Updated Aug 5, 2026

Use-after-free in affected Linux kernel 6.x releases allows local users to access released I2C state during mgag200 device teardown. Managed Linux-device cleanup releases the I2C adapter while struct drm_connector.ddc still holds its address, leaving a stale pointer. Reachability requires the mgag200 driver and the device-removal teardown order; the CNA does not specify a consequence beyond stale-pointer access.
