Out-of-Bounds Read in Alps WLAN STA Driver Causing Info Disclosure
CVE-2025-20693 Published on July 8, 2025
In wlan STA driver, there is a possible out of bounds read due to an incorrect bounds check. This could lead to remote (proximal/adjacent) information disclosure with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: ALPS09812521; Issue ID: MSV-3421.
Vulnerability Analysis
Weakness Type
Out-of-bounds Read
The software reads data past the end, or before the beginning, of the intended buffer. Typically, this can allow attackers to read sensitive information from other memory locations or cause a crash. A crash can occur when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string. The expected sentinel might not be located in the out-of-bounds memory, causing excessive data to be read, leading to a segmentation fault or a buffer overflow. The software may modify an index or perform pointer arithmetic that references a memory location that is outside of the boundaries of the buffer. A subsequent read operation then produces undefined or unexpected results.
