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/

Affected products

• Linux kernel: from 6.5 before 7.0.11; 7.1-rc1, 7.1-rc2, 7.1-rc3, 7.1-rc4 — fixed in 7.0.11

How to fix

Upgrade to a fixed version: Linux kernel 7.0.11. Check the vendor advisory for mitigations.
