CVE-2023-53284

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/msm/dpu: check for null return of devm_kzalloc() in dpu_writeback_init()<br /> <br /> Because of the possilble failure of devm_kzalloc(), dpu_wb_conn might<br /> be NULL and will cause null pointer dereference later.<br /> <br /> Therefore, it might be better to check it and directly return -ENOMEM.<br /> <br /> Patchwork: https://patchwork.freedesktop.org/patch/512277/<br /> [DB: fixed typo in commit message]
