CVE-2023-52510

Kernel memory misuse via double clock unregistration

Published Mar 2, 2024 · Updated May 11, 2026

Use-after-free in the Linux ca8210 IEEE 802.15.4 driver allows local users to trigger invalid kernel-memory access during device probing. The failure path unregisters priv->clk before ca8210_probe calls cleanup, which unregisters the same clock again. Reachability requires CA8210 device probing and failure in of_clk_add_provider; the published record does not demonstrate code execution or a reliable crash.
