AI-suggested
A fix for this memory leak has been implemented and merged into the Linux kernel. Users should update to the fixed versions identified by the commits listed in establishedFacts.fixedVersions to remediate this issue. No additional mitigation steps are necessary once the kernel is updated.
Description
A memory leak vulnerability was identified and fixed in the Linux kernel's amdgpu driver, specifically in the amdgpu_acpi_enumerate_xcc() function. The issue occurs when amdgpu_acpi_dev_init() returns an -ENOMEM error, causing the function to return without freeing allocated memory, leading to a leak. The fix ensures proper memory release on error paths.
