Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> drm/msm/snapshot: fix dumping of the unaligned regions<br /> <br /> The snapshotting code internally aligns data segment to 16 bytes. This<br /> works fine for DPU code (where most of the regions are aligned), but<br /> fails for snapshotting of the DSI data (because DSI data region is<br /> shifted by 4 bytes). Fix the code by removing length alignment and by<br /> accurately printing last registers in the region. While reworking the<br /> code also fix the 16x memory overallocation in<br /> msm_disp_state_dump_regs().<br /> <br /> Patchwork: https://patchwork.freedesktop.org/patch/725449/
