NVD Description

Note: Versions mentioned in the description apply only to the upstream bpftool package and not the bpftool package as distributed by Centos.

In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: dvm: Fix memcpy: detected field-spanning write backtrace

A received TKIP key may be up to 32 bytes because it may contain MIC rx/tx keys too. These are not used by iwl and copying these over overflows the iwl_keyinfo.key field.

Add a check to not copy more data to iwl_keyinfo.key then will fit.

This fixes backtraces like this one:

memcpy: detected field-spanning write (size 32) of single field "sta_cmd.key.key" at drivers/net/wireless/intel/iwlwifi/dvm/sta.c:1103 (size 16) WARNING: CPU: 1 PID: 946 at drivers/net/wireless/intel/iwlwifi/dvm/sta.c:1103 iwlagn_send_sta_key+0x375/0x390 [iwldvm] <snip> Hardware name: Dell Inc.
