CVE-2023-52790

  2. Vulnerabilities (CVE)
  3. CVE-2023-52790
In the Linux kernel, the following vulnerability has been resolved: swiotlb: fix out-of-bounds TLB allocations with CONFIG_SWIOTLB_DYNAMIC Limit the free list length to the size of the IO TLB. Transient pool can be smaller than IO_TLB_SEGSIZE, but the free list is initialized with the assumption that the total number of slots is a multiple of IO_TLB_SEGSIZE. As a result, swiotlb_area_find_slots() may allocate slots past the end of a transient IO TLB buffer.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: swiotlb: corrige asignaciones de TLB fuera de los límites con CONFIG_SWIOTLB_DYNAMIC Limita la longitud de la lista libre al tamaño del IO TLB. El grupo transitorio puede ser más pequeño que IO_TLB_SEGSIZE, pero la lista libre se inicializa asumiendo que el número total de ranuras es un múltiplo de IO_TLB_SEGSIZE. Como resultado, swiotlb_area_find_slots() puede asignar ranuras más allá del final de un búfer IO TLB transitorio.
