Descriptions

In the Linux kernel, the following vulnerability has been resolved: wifi: wilc1000: use vmm_table as array in wilc struct Enabling KASAN and running some iperf tests raises some memory issues with
vmm_table: BUG: KASAN: slab-out-of-bounds in wilc_wlan_handle_txq+0x6ac/0xdb4
Write of size 4 at addr c3a61540 by task wlan0-tx/95 KASAN detects that we are writing data beyond range allocated to vmm_table.
There is indeed a mismatch between the size passed to allocator in
wilc_wlan_init, and the range of possible indexes used later: allocation
size is missing a multiplication by sizeof(u32)

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: wifi: wilc1000: use vmm_table como matriz en wilc struct. Al habilitar KASAN y ejecutar algunas pruebas de iperf se generan algunos problemas de memoria con vmm_table: BUG: KASAN: slab-out-of-bounds en wilc_wlan_handle_txq +0x6ac/0xdb4 Escritura de tamaño 4 en la dirección c3a61540 mediante la tarea wlan0-tx/95 KASAN detecta que estamos escribiendo datos más allá del rango asignado a vmm_table. De hecho, existe una discrepancia entre el tamaño pasado al asignador en wilc_wlan_init y el rango de posibles índices utilizados más adelante: al tamaño de la asignación le falta una multiplicación por sizeof(u32)
