CVE-2024-27392

In the Linux kernel, the following vulnerability has been resolved: nvme: host: fix double-free of struct nvme_id_ns in ns_update_nuse() When nvme_identify_ns() fails, it frees the pointer to the struct nvme_id_ns before it returns. However, ns_update_nuse() calls kfree() for the pointer even when nvme_identify_ns() fails. This results in KASAN double-free, which was observed with blktests nvme/045 with proposed patches [1] on the kernel v6.8-rc7. Fix the double-free by skipping kfree() when nvme_identify_ns() fails.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: nvme: host: corrige la doble liberación de la estructura nvme_id_ns en ns_update_nuse() Cuando nvme_identify_ns() falla, libera el puntero a la estructura nvme_id_ns antes de que regrese. Sin embargo, ns_update_nuse() llama a kfree() para el puntero incluso cuando nvme_identify_ns() falla. Esto da como resultado KASAN double-free, que se observó con blktests nvme/045 con parches propuestos [1] en el kernel v6.8-rc7. Corrija el doble libre omitiendo kfree() cuando falla nvme_identify_ns().
