Description (CNA)
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.
