Description

Memory corruption while submitting a large list of sync points in an AUX command to the IOCTL_KGSL_GPU_AUX_COMMAND.

• CWE-823Use of Out-of-range Pointer OffsetThe product performs pointer arithmetic on a valid pointer, but it uses an offset that can point outside of the intended range of valid memory locations for the resulting pointer.
• CWE-119Improper Restriction of Operations within the Bounds of a Memory BufferThe product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
