Description
A vulnerability in the Linux kernel's drm/tegra component was resolved by adding a missing call to put_pid() to properly free a PID reference. The issue involved host1x_memory_context_alloc() not taking ownership of the PID, leading to a resource leak. This flaw has been fixed in specific Linux kernel versions. The vulnerability is rated medium severity and no known exploits are reported in the wild.
