GHSA-2R6W-8QQX-7JQ3

Vulnerability from github – Published: 2026-02-04 18:30 – Updated: 2026-03-13 21:31
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

spi: spi-sprd-adi: Fix double free in probe error path

The driver currently uses spi_alloc_host() to allocate the controller but registers it using devm_spi_register_controller().

If devm_register_restart_handler() fails, the code jumps to the put_ctlr label and calls spi_controller_put(). However, since the controller was registered via a devm function, the device core will automatically call spi_controller_put() again when the probe fails. This results in a double-free of the spi_controller structure.

Fix this by switching to devm_spi_alloc_host() and removing the manual spi_controller_put() call.

Summary
arenavec has multiple memory corruption vulnerabilities in safe APIs
Details

The crate has the following vulnerabilities:

  • The public trait arenavec::common::AllocHandle allows the return of raw pointers through its methods allocate and allocate_or_extend. However, the trait is not marked as unsafe, meaning users of the crate may implement it under the assumption that the library safely handles the returned raw pointers. These raw pointers can later be dereferenced within safe APIs of the crate-such as arenavec::common::SliceVec::push-potentially leading to arbitrary memory access.

  • The safe API arenavec::common::SliceVec::reserve can reach the private function arenavec::common::allocate_inner. Incorrect behavior in allocate_inner may result in a SliceVec with an increased capacity, even though the underlying memory has not actually been expanded. This mismatch between SliceVec.capacity and the actual reserved memory can lead to a heap buffer overflow.

  • The safe API arenavec::common::SliceVec::split_off can duplicate the ownership of the elements in self (of type SliceVec) if they implement the Drop trait. Specifically, when at == 0, the method returns a new SliceVec with the same length as self. Since both self and the returned object point to the same heap memory, dropping one will deallocate the shared memory. When the other is subsequently dropped, it will attempt to free the same memory again, resulting in a double free violation.

Mitigation
Architecture and Design

Choose a language that provides automatic memory management.

Mitigation
Implementation

Ensure that each allocation is freed only once. After freeing a chunk, set the pointer to NULL to ensure the pointer cannot be freed again. In complicated error conditions, be sure that clean-up routines respect the state of allocation properly. If the language is object oriented, ensure that object destructors delete each chunk of memory only once.

Mitigation
Implementation

Use a static analysis tool to find double free instances.
