Description

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