HIGH Summary
In the Linux kernel, the following vulnerability has been resolved: drm/amd: check num of link levels when update pcie param In SR-IOV environment, the value of pcie_table->num_of_link_levels will be 0, and num_of_levels - 1 will cause array index out of bounds
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Overflow Buffers Buffer Overflow attacks target improper or missing bounds checking on buffer operations, typically triggered by input injected by an attacker. As a consequence, an attacker is able to write past the boundaries of allocated buffer regions in memory, causing a program crash or potentially redirection of execution as per the attackers' choice.
