Description OSIDB Bzimport 2025-11-12 23:03:51 UTC 
In the Linux kernel, the following vulnerability has been resolved:

pwm: berlin: Fix wrong register in suspend/resume

The 'enable' register should be BERLIN_PWM_EN rather than
BERLIN_PWM_ENABLE, otherwise, the driver accesses wrong address, there
will be cpu exception then kernel panic during suspend/resume.
