What to do
AI-suggested
A fix has been implemented in the Linux kernel source to address this issue by changing the memory allocation method in the drm/msm/dpu driver. Users should apply the official kernel updates that include this patch. Patch status is not explicitly confirmed here; check the vendor or kernel mailing list advisories for the exact fixed versions and update accordingly.
Description
In the Linux kernel, the following vulnerability has been resolved: drm/msm/dpu: don't mix devm and drmm functions Mixing devm and drmm functions will result in a use-after-free on msm driver teardown if userspace keeps a reference on the drm device: The WB connector data will be destroyed because of the use of devm_kzalloc()), while the usersoace still can try interacting with the WB connector (which uses drmm_ functions). Change dpu_writeback_init() to use drmm_. Patchwork: https://patchwork.freedesktop.org/patch/722656/
