Description OSIDB Bzimport 2026-09-24 16:47:07 UTC 
In the Linux kernel, the following vulnerability has been resolved:

media: chips-media: wave5: Release m2m_ctx after Instance Removed from List

Possible use after free if IRQ thread manages to obtain spinlock between
m2m_ctx release and wave5_release function removing stream instance from
list of active instances. The IRQ thread looks for the m2m_ctx which is
freed so null pointer dereference occurs.
