CVE-2026-43263 Details
Description
In the Linux kernel, the following vulnerability has been resolved: media: chips-media: wave5: Fix Null reference while testing fluster When multi instances are created/destroyed, many interrupts happens and structures for decoder are removed. "struct vpu_instance" this structure is shared for all flow in the decoder, so if the structure is not protected by lock, Null dereference could happens sometimes. IRQ Handler was spilt to two phases and Lock was added as well.
A null pointer dereference vulnerability has been addressed in the Linux kernel's media chips for the Wave5 decoder. This issue arose because the 'vpu_instance' structure, shared across the decoder's workflow, was not properly protected by locks. During the creation and destruction of multiple instances, unprotected access led to occasional null dereferences. The vulnerability has been mitigated by splitting the interrupt request (IRQ) handling into two phases and introducing appropriate locking mechanisms.
