Description
A flaw was found in the Linux kernel's accel/amdxdna driver. The aie2_populate_range() function, responsible for managing memory structures, fails to properly release a reference to a memory structure (mm_struct). This oversight leads to a memory leak, which over time could result in resource exhaustion and potentially impact system stability.
