In the Linux kernel, the following vulnerability has been resolved: iio: buffer: Ensure bounce buffer used for unaligned case is zeroed. iio_push_to_buffers_with_ts_unaligned() leaks uninitialized heap memory to userspace if the data passed in is not a multiple of 8 bytes and the timestamp is enabled. Specify __GFP_ZERO for the devm_krealloc() to ensure any extra space is cleared.
