A vulnerability was detected in BioStar VALKYRIE AURORA 2.10.2411.0800. This vulnerability affects the function sub1105C of the file BSRVSIO64.sys of the component IOCTL Handler. The manipulation of the argument PhysicalAddress results in write-what-where condition. The attack needs to be approached locally. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

A security vulnerability has been detected in BioStar VIVID LED DJ 4.0.2411.1500. This affects the function sub1105C of the file BSLED64.sys of the component IOCTL Handler. The manipulation of the argument AssociatedIrp leads to write-what-where condition. Local access is required to approach this attack. The exploit has been disclosed publicly and may be used. The vendor was contacted early about this disclosure but did not respond in any way.

An issue was discovered in BSRCIO64.sys in Biostar RACING GT Evo 2.1.1905.1700. A low-integrity process can open the driver's device object and issue IOCTLs to read or write to arbitrary physical memory locations (or call an arbitrary address), leading to execution of arbitrary code. This is associated with 0x226040, 0x226044, and 0x226000.
