CVE-2026-29009
Description
A flaw was found in U-Boot. A buffer overflow vulnerability exists in the nfs_readlink_reply() function when the Network File System (NFS) command is enabled. A malicious or compromised NFS server can exploit this by sending multiple relative symlink targets, exceeding the buffer's capacity. This can lead to memory corruption and potentially allow an attacker to control the NFS client's state machine.
Statement

Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Modify Memory; Execute Unauthorized Code or Commands
Buffer overflows often can be used to execute arbitrary code, which is usually outside the scope of the product's implicit security policy. This can often be used to subvert any other security service.
Availability
Technical Impact: Modify Memory; DoS: Crash, Exit, or Restart; DoS: Resource Consumption (CPU)
Buffer overflows generally lead to crashes. Other attacks leading to lack of availability are possible, including putting the product into an infinite loop.
