AI-suggested
An official patch is available and should be applied to affected linux-aws kernel versions to resolve the memory leak. Updating to patched kernel versions listed in the advisory will mitigate this vulnerability.
Description
A memory region leak vulnerability in the Linux kernel's sunxi reset driver was fixed. The issue occurred in sunxi_reset_init() when ioremap() failed, causing the memory region obtained by request_mem_region() to not be released properly. This resource leak could affect system stability. The vulnerability affects specific linux-aws kernel versions and has been patched.
