CVE-2023-53851

Kernel memory corruption via stale eDP auxiliary devices

Published Dec 9, 2025 · Updated Aug 5, 2026

Use-after-free in the Linux MSM DisplayPort driver allows local attackers to disclose or corrupt kernel memory during eDP teardown. The DP controller can be torn down after devres leaves its auxiliary-bus panel device populated, so later EDID access dereferences freed DP resources. Reachability is limited to Qualcomm MSM systems with an internal eDP panel during deferred probe or component unbind; the fault can corrupt kernel state, crash the system, or prevent the display controller from starting.
