If index is 32, it will attempt to\naccess a non-existent 33rd bit, leading to out-of-bounds access.\nChange the boundary check from index > 32 to index >= 32 to resolve this\nissue."

"value": "AV:L - The vulnerable code is reached only through ioctls (DMX_SET_PES_FILTER/DMX_ADD_PID plus DMX_START) on the local DVB demux device node /dev/dvb/adapterN/demux0. No network or remote-peer data reaches rtl2830_pid_filter().\nAC:L - The attacker drives the path deterministically by adding PID filter feeds via ioctl on an already-attached RTL2831U tuner; there is no race, no memory-layout dependency, and no unpredictable state involved in reaching the boundary check.\nPR:L - No capability check exists on the path — dvb_usb_start_feed() and rtl28xxu_pid_filter() perform no privilege validation — so only permission to open the DVB demux character device (commonly the video group, and world-accessible on many embedded/set-top media appliances) is needed.\nUI:N - Once the tuner device is bound, the attacker triggers the path entirely on their own via ioctls on the demux node; no victim action is required.\nS:U - The out-of-bounds write and any resulting corruption stay within the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - An out-of-bounds bit write past the end of the filters bitmap corrupts adjacent kernel memory in struct rtl2830_dev, and per kernel scoring guidance memory corruption of this kind is treated as leverageable toward information disclosure.\nI:H - This is an out-of-bounds write — set_bit()/clear_bit() operate on bit 32 of a 32-bit filter bitmap, modifying kernel memory outside the intended object field, and the register write also goes past the end of the demodulator's PID register block.\nA:H - Corrupting kernel memory adjacent to the filter bitmap (including the driver's fe_status word on 32-bit builds) and writing an out-of-range demodulator register can leave the driver and device in an inconsistent state leading to a crash or hang."
