Description SMASH SMASH 2024-05-24 15:48:44 UTC

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

i2c: dev: copy userspace array safely

i2c-dev.c utilizes memdup_user() to copy a userspace array. This is done
without an overflow check.

Use the new wrapper memdup_array_user() to copy the array more safely.
