In the Linux kernel, the following vulnerability has been resolved: media:
gspca: cpia1: shift-out-of-bounds in set_flicker Syzkaller reported the
following issue: UBSAN: shift-out-of-bounds in
drivers/media/usb/gspca/cpia1.c:1031:27 shift exponent 245 is too large for
32-bit type ‘int’ When the value of the variable “sd->params.exposure.gain”
exceeds the number of bits in an integer, a shift-out-of-bounds error is
reported. It is triggered because the variable “currentexp” cannot be
left-shifted by more than the number of bits in an integer. In order to
avoid invalid range during left-shift, the conditional expression is added.
