No network or remote data feeds into the index parameter.\nAC:L - On a system with an RTL2832U DVB-T tuner attached and hardware PID filtering active, the attacker drives the filter-index path directly and deterministically via repeated ioctls, with no race to win and no memory layout to groom.\nPR:L - No capability check exists anywhere along the dmxdev/dvb_usb_core/rtl2832 path; the only gate is DVB device-node permissions, which grant access to ordinary users in the video group on desktops and to unprivileged media processes on embedded receivers and set-top boxes.\nUI:N - Once the tuner device is present and bound, the attacker issues the demux ioctls entirely on their own; no victim action is needed to trigger the out-of-bounds write.\nS:U - The out-of-bounds write corrupts kernel memory within the driver's own security authority; there is no crossing of a VM, IOMMU, or sandbox boundary.\nC:H - Out-of-bounds writes past the intended 32-bit filter field corrupt adjacent kernel state, and memory corruption of this class is conventionally treated as leverageable into read primitives and kernel information disclosure.\nI:H - This is a direct out-of-bounds write: set_bit/clear_bit operate beyond the 32-bit dev->filters field, and the stray regmap_bulk_write places attacker-supplied PID bytes into an unintended demod register.\nA:H - Corrupting memory beyond the intended field, including the adjacent slave_ts control flag, can destabilize the driver and the kernel, and any such out-of-bounds write is treated as capable of producing a crash or oops." } ] }
