CVE-2026-46016
Description
A flaw was found in the Linux kernel's remoteproc xlnx component. This vulnerability occurs when the system attempts to process an Inter-Processor Interrupt (IPI) message without properly verifying its contents. An attacker could exploit this by causing the system to access an invalid memory location, leading to a system crash. This could result in a denial of service, making the system unavailable to legitimate users.
Understanding the Weakness (CWE)
Availability
Technical Impact: DoS: Crash, Exit, or Restart
NULL pointer dereferences usually result in the failure of the process unless exception handling (on some platforms) is available and implemented. Even when exception handling is being used, it can still be very difficult to return the software to a safe state of operation.
Integrity,Confidentiality
Technical Impact: Execute Unauthorized Code or Commands; Read Memory; Modify Memory
In rare circumstances, when NULL is equivalent to the 0x0 memory address and privileged code can access it, then writing or reading memory is possible, which may lead to code execution.
