In the Linux kernel, the following vulnerability has been resolved:
accel/amdxdna: Adjust size for copy_to_user()
The amount of data returned to user space should be limited by the buffer
size provided by the application. If the buffer is smaller than the data
size, return only the portion that fits instead of failing.
A flaw was found in the accel/amdxdna driver in the Linux kernel. This vulnerability occurs due to improper handling of user-provided buffer sizes when copying data from kernel space to user space. A local attacker could exploit this by providing a buffer smaller than the expected data size, potentially leading to information disclosure of sensitive kernel memory or a denial of service.
