Vulnerability from github
In the Linux kernel, the following vulnerability has been resolved:
scsi: ufs: core: Fix shift issue in ufshcd_clear_cmd()
When task_tag >= 32 (in MCQ mode) and sizeof(unsigned int) == 4, 1U << task_tag will out of bounds for a u32 mask. Fix this up to prevent SHIFT_ISSUE (bitwise shifts that are out of bounds for their data type).
