Severity ?

5.6 (Medium) - CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:H

Details

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)
