Doc Text:
A flaw was found in the Linux kernel's Adreno GPU driver. This use-after-free vulnerability occurs in the `a6xx_gpu_init()` function. Specifically, the `a6xx_destroy()` function frees the `a6xx_gpu` memory, but `adreno_gpu` continues to point to the freed memory. An attacker could potentially exploit this to cause a denial of service or achieve arbitrary code execution.

Description OSIDB Bzimport 2026-09-17 17:34:09 UTC 
In the Linux kernel, the following vulnerability has been resolved:

drm/msm/adreno: fix use after free on error path in a6xx_gpu_init()

The a6xx_destroy() function frees "a6xx_gpu" and so "adreno_gpu" points
to freed memory.  Preserve the error code before freeing the memory to
avoid a use after free.
