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