Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 5.16-rc6

Description An issue was discovered in the Linux kernel where the imx register uart clocks function in drivers/clk/imx/clk.c lacks a check of the return value of kcalloc(), leading to a null pointer dereference. This could allow an attacker to cause a denial of service or potentially elevate their privileges.

Recommendations For Linux kernel versions prior to 5.16-rc6, consider applying a patch that adds a check for the return value of kcalloc() in the imx register uart clocks function to prevent null pointer dereferences. As a temporary workaround, restricting access to the imx register uart clocks function may help minimize the risk of exploitation.
