CVE-2026-68228

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> media: chips-media: wave5: Move src_buf Removal to finish_encode<br /> <br /> During encoder processing, there is a case where the IRQ response could<br /> return the buffer back to userspace via v4l2_m2m_buf_done call. In this<br /> time, userspace could queue up this same buffer before start_encode removes<br /> the index from the ready queue. This would then lead to a case where the<br /> buffer in the ready queue could be a self loop due to the<br /> WRITE_ONCE(prev-&gt;next, new) call in __list_add.<br /> <br /> When __list_del is finally called, the loop is already made so nothing<br /> points back to ready queue list head and pointers are poisoned.<br /> <br /> A buffer should not be marked as DONE before the buffer is removed from<br /> m2m ready queue. Move removal entirely to finish_encode.
