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.

No CVSS v4.0

No CVSS v3.1
