CVE-2025-68172 Details
Description
In the Linux kernel, the following vulnerability has been resolved: crypto: aspeed - fix double free caused by devm The clock obtained via devm_clk_get_enabled() is automatically managed by devres and will be disabled and freed on driver detach. Manually calling clk_disable_unprepare() in error path and remove function causes double free. Remove the manual clock cleanup in both aspeed_acry_probe()'s error path and aspeed_acry_remove().
A double free vulnerability has been identified in the Linux kernel's crypto subsystem, specifically within the Aspeed ACRY driver. This issue arises from improper management of a clock resource obtained through 'devm_clk_get_enabled()'. While this clock is automatically handled by the device resource management system and freed when the driver is detached, the ACRY driver incorrectly calls 'clk_disable_unprepare()' during error handling and cleanup, leading to a double free condition. The vulnerability affects the Linux kernel stable tree.
The vulnerability has been fixed in the Linux kernel. Users should upgrade to the latest version where this issue has been addressed.
