- Summary
- staging: sm750fb: fix division by zero in ps_to_hz()
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
staging: sm750fb: fix division by zero in pstohz()
pstohz() is called from hwsm750crtcsetmode() without validating that pixclock is non-zero. A zero pixclock passed via FBIOPUT_VSCREENINFO causes a division by zero.
Fix by rejecting zero pixclock in lynxfbopscheck_var(), consistent with other framebuffer drivers.
