n the Linux kernel, the following vulnerability has been resolved: PCI: kirin: Fix buffer overflow in kirin_pcie_parse_port() Within kirin_pcie_parse_port(), the pcie->num_slots is compared to pcie->gpio_id_reset size (MAX_PCI_SLOTS) which is correct and would lead to an overflow. Thus, fix condition to pcie->num_slots + 1 >= MAX_PCI_SLOTS and move pcie->num_slots increment below the if-statement to avoid out-of-bounds array access. Found by Linux Verification Center (linuxtesting.org) with SVACE. [kwilczynski: commit log]

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: PCI: kirin: Se ha corregido el desbordamiento de búfer en kirin_pcie_parse_port(). En kirin_pcie_parse_port(), el tamaño de pcie->num_slots se compara con el tamaño de pcie->gpio_id_reset (MAX_PCI_SLOTS), que es correcto y provocaría un desbordamiento. Por lo tanto, se ha corregido la condición a pcie->num_slots + 1 >= MAX_PCI_SLOTS y se ha movido el incremento de pcie->num_slots por debajo de la instrucción if para evitar el acceso a la matriz fuera de los límites. Encontrado por Linux Verification Center (linuxtesting.org) con SVACE. [kwilczynski: registro de confirmaciones]
