Local Input Validation Bug in AMD PMF Driver Enables OOB Info Disclosure
CVE-2025-48520 Published on May 15, 2026
An improper input validation vulnerability within the AMD Platform Management Framework (PMF) driver can allow a local attacker to read Out-of-Bounds potentially resulting in information disclosure or a crash
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.
