In all Qualcomm products with Android releases from CAF using the Linux kernel, multiple values received from firmware are not properly validated in wma_get_ll_stats_ext_buf() and are used to allocate the sizes of buffers and may be vulnerable to integer overflow leading to buffer overflow.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
