Ubuntu.comUB:CVE-2023-52756CVE-2023-52756
In the Linux kernel, the following vulnerability has been resolved: pwm:
Fix double shift bug These enums are passed to set/test_bit(). The
set/test_bit() functions take a bit number instead of a shifted value.
Passing a shifted value is a double shift bug like doing BIT(BIT(1)). The
double shift bug doesn’t cause a problem here because we are only checking
0 and 1 but if the value was 5 or above then it can lead to a buffer
overflow.
