  2. Vulnerabilities (CVE)
  3. CVE-2024-56767
In the Linux kernel, the following vulnerability has been resolved: dmaengine: at_xdmac: avoid null_prt_deref in at_xdmac_prep_dma_memset The at_xdmac_memset_create_desc may return NULL, which will lead to a null pointer dereference. For example, the len input is error, or the atchan->free_descs_list is empty and memory is exhausted. Therefore, add check to avoid this.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: dmaengine: at_xdmac: evitar null_prt_deref en at_xdmac_prep_dma_memset El parámetro at_xdmac_memset_create_desc puede devolver NULL, lo que provocará una desreferencia de puntero nulo. Por ejemplo, la entrada len es un error o la lista atchan->free_descs_list está vacía y la memoria está agotada. Por lo tanto, agregue una comprobación para evitar esto.
