About this tag
The imx sc key tag covers discussions about the IMX SCU key driver (imx_sc_key) in the Linux kernel, including a security patch for CVE-2025-40262. This vulnerability involved a memory-corruption bug during module unload, where the driver passed a stack variable address instead of the correct pointer. The fix corrected this by using the intended priv argument, preventing kernel memory corruption. Topics include kernel module cleanup, pointer handling, and upstream patches for the i.MX system controller unit key driver.
