Detailsinfo

A vulnerability was found in Linux Kernel up to 5.16.2 (Operating System) and classified as problematic. Affected by this issue is the function ufs_mtk_init_va09_pwr_ctrl of the file drivers/scsi/ufs/ufs-mediatek.c. The manipulation of the argument regulator_get with an unknown input leads to a return value vulnerability. Using CWE to declare the problem leads to CWE-252. The product does not check the return value from a method or function, which can prevent it from detecting unexpected states and conditions. The impact remains unknown. CVE summarizes:

In the Linux kernel before 5.16.3, drivers/scsi/ufs/ufs-mediatek.c misinterprets the regulator_get return value (expects it to be NULL in the error case, whereas it is actually an error pointer).
