CVE-2024-57887

Kernel memory corruption via stale device-tree pointer

Published Jan 15, 2025 · Updated Aug 5, 2026

Use-after-free in the ADV7533 DSI bridge driver in Linux 4.8 and later allows local users to corrupt kernel memory during device attachment. adv7533_parse_dt() drops the host_node reference while retaining its pointer, and adv7533_attach_dsi() later dereferences that stale device-tree node. Reaching the flaw requires local low-privileged access and an ADV7533 device-tree configuration; published records do not define a reliable post-corruption outcome.
