CVE-2023-52510

Severity CVSS v4.0:
Pending analysis
Type:

Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ieee802154: ca8210: Fix a potential UAF in ca8210_probe<br /> <br /> If of_clk_add_provider() fails in ca8210_register_ext_clock(),<br /> it calls clk_unregister() to release priv-&gt;clk and returns an<br /> error. However, the caller ca8210_probe() then calls ca8210_remove(),<br /> where priv-&gt;clk is freed again in ca8210_unregister_ext_clock(). In<br /> this case, a use-after-free may happen in the second time we call<br /> clk_unregister().<br /> <br /> Fix this by removing the first clk_unregister(). Also, priv-&gt;clk could<br /> be an error code on failure of clk_register_fixed_rate(). Use<br /> IS_ERR_OR_NULL to catch this case in ca8210_unregister_ext_clock().
