- Summary
- drm/msm: Avoid NULL dereference in msm_disp_state_print_regs()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
drm/msm: Avoid NULL dereference in msmdispstateprintregs()
If the allocation in msmdispstatedumpregs() failed then
block->statecan be NULL. The msmdispstateprintregs() function does have code to try to handle it with:if (*reg) dump_addr = *reg;
...but since "dump_addr" is initialized to NULL the above is actually a noop. The code then goes on to dereference
dump_addr.Make the function print "Registers not stored" when it sees a NULL to solve this. Since we're touching the code, fix msmdispstateprintregs() not to pointlessly take a double-pointer and properly mark the pointer as
