AI-suggested
A patch is available and should be applied by updating to the fixed Linux kernel versions as provided by the vendor. For Ubuntu users, updated linux-image packages for NVIDIA Tegra systems address this issue. After updating, a system reboot is required. Due to ABI changes, recompilation and reinstallation of third-party kernel modules may be necessary. Follow vendor instructions for applying these updates.
Description
A memory leak vulnerability in the Linux kernel's dmaengine Qualcomm GPI driver (gpi_peripheral_config function) was fixed. The issue occurs when krealloc() fails and the original memory reference is lost, causing a leak. This was identified through static analysis and code review. The vulnerability affects specific Linux kernel versions and has a medium severity with a CVSS score of 5.5. A patch is available and included in updated Linux kernel packages, notably for Ubuntu NVIDIA Tegra systems.
