Ubuntu.comUB:CVE-2024-38549CVE-2024-38549
In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: Add 0 size check to mtk_drm_gem_obj
Add a check to mtk_drm_gem_init if we attempt to allocate a GEM object
of 0 bytes. Currently, no such check exists and the kernel will panic if
a userspace application attempts to allocate a 0x0 GBM buffer.
Tested by attempting to allocate a 0x0 GBM buffer on an MT8188 and
verifying that we now return EINVAL.
