In the Linux kernel, the following vulnerability has been resolved:

ASoC: cs35l41: Fix an out-of-bounds access in otp_packed_element_t

The CS35L41_NUM_OTP_ELEM is 100, but only 99 entries are defined in
the array otp_map_1/2[CS35L41_NUM_OTP_ELEM], this will trigger UBSAN
to report a shift-out-of-bounds warning in the cs35l41_otp_unpack()
since the last entry in the array will result in GENMASK(-1, 0).

UBSAN reports this problem:
 UBSAN: shift-out-of-bounds in /home/hwang4/build/jammy/jammy/sound/soc/codecs/cs35l41-lib.c:836:8
 shift exponent 64 is too large for 64-bit type 'long unsigned int'
 CPU: 10 PID: 595 Comm: systemd-udevd Not tainted 5.15.0-23-generic #23
 Hardware name: LENOVO \x02MFG_IN_GO/\x02MFG_IN_GO, BIOS N3GET19W (1.00 ) 03/11/2022
