CVE-2026-64154 Details
Description
In the Linux kernel, the following vulnerability has been resolved: drm/msm/adreno: Fix a reference leak in a6xx_gpu_init() In a6xx_gpu_init(), node is obtained via of_parse_phandle(). While there was a manual of_node_put() at the end of the common path, several early error returns would bypass this call, resulting in a reference leak. Fix this by using the __free(device_node) cleanup handler to release the reference when the variable goes out of scope. Patchwork: https://patchwork.freedesktop.org/patch/700661/
A reference leak vulnerability has been identified in the Linux kernel's handling of Adreno A6XX GPUs. The issue arises in the 'a6xx_gpu_init()' function, where a device node is parsed but not properly released in all error scenarios, leading to a memory leak. This vulnerability affects the Linux kernel stable tree.
Users can apply the patch available in the Linux kernel stable tree to address this vulnerability. The patch is included in the official Linux kernel repository.
