CVE-2023-52510

Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a potential use-after-free (UAF) in the ca8210 probe function. If of clk add provider() fails in ca8210 register ext clock(), it calls clk unregister() to release priv->clk and returns an error. However, the caller ca8210 probe() then calls ca8210 remove(), where priv->clk is freed again in ca8210 unregister ext clock(). This can lead to a use-after-free when clk unregister() is called the second time. The fix involves removing the first clk unregister() call and using IS ERR OR NULL to catch the case where priv->clk is an error code on failure of clk register fixed rate().

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
