In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
media: chips-media: wave5: Move src_buf Removal to finish_encode<\/p>\n
During encoder processing, there is a case where the IRQ response could
\nreturn the buffer back to userspace via v4l2_m2m_buf_done call. In this
\ntime, userspace could queue up this same buffer before start_encode removes
\nthe index from the ready queue. This would then lead to a case where the
\nbuffer in the ready queue could be a self loop due to the
\nWRITE_ONCE(prev->next, new) call in __list_add.<\/p>\n
When __list_del is finally called, the loop is already made so nothing
\npoints back to ready queue list head and pointers are poisoned.<\/p>\n
A buffer should not be marked as DONE before the buffer is removed from
\nm2m ready queue. Move removal entirely to finish_encode.<\/p>\n","protected":false},"excerpt":{"rendered":"
