CVE-2024-57915
Description
[REJECTED CVE] A vulnerability in the Linux kernel's USB gadget subsystem allowed a race condition where gserial_disconnect could clear gser->ioport during unbinding, leading to a null pointer dereference in gs_read_complete, potentially causing a kernel crash. An attacker could exploit this by repeatedly triggering gadget reconfiguration, leading to denial of service. This issue has been resolved by disabling the endpoint before setting the port to null, preventing access to freed resources.
Statement
This CVE has been rejected upstream: https://lore.kernel.org/linux-cve-announce/2025021308-REJECTED-3f47@gregkh/

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.
