Kernel crash via GSP queue pointer miscalculation
Published Feb 27, 2025 · Updated Aug 5, 2026
NULL pointer dereference in affected Linux kernels allows local users to crash the system through Nouveau GSP message handling. In r535_gsp_msg_recv, nvkm advances the queue read pointer by only the RPC header and body sizes, omitting the message header size. With Nouveau GSP processing active, a two-page non-rollback event causes the previous body to be parsed as the next header, underflowing the copy length and dereferencing a NULL pointer in kernel context.
