| Vector | AV:L/AC:L/Au:S/C:N/I:N/A:C |
Name of the Vulnerable Software and Affected Versions
Linux kernel (affected versions not specified)
Description
The Linux kernel contains a flaw in the crypto/aspeed module where a double free issue can occur due to improper clock management with devm clk get enabled(). Specifically, the clock obtained through this function is automatically managed by devres, which handles disabling and freeing it upon driver detachment. Manually calling
clk disable unprepare() in the error path and remove function leads to a double free condition. The issue is addressed by removing the manual clock cleanup in both aspeed acry probe()'s error path and aspeed acry remove().Recommendations
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
