In the Linux kernel, the following vulnerability has been resolved:

media: s5p-mfc: Clear workbit to handle error condition

During error on CLOSE_INSTANCE command, ctx_work_bits was not getting
cleared. During consequent mfc execution NULL pointer dereferencing of
this context led to kernel panic. This patch fixes this issue by making
sure to clear ctx_work_bits always.
