Title:
UBSAN: shift-out-of-bounds in WiFi driver (iwlwifi/mvm/mac-ctxt.c)
Status in linux package in Ubuntu:
Confirmed
Bug description:
Hello all!
On Ubuntu 20.04.5 LTS, when I use the mdk3 tool
(https://github.com/aircrack-ng/mdk3, also available in Ubuntu PPA),
it raises a kernel exception in the Wi-Fi driver:
UBSAN: shift-out-of-bounds in
/build/linux-hwe-5.15-ZCQu4B/linux-hwe-5.15-5.15.0/drivers/net/wireless/intel/iwlwifi/mvm/mac-ctxt.c:669:22
shift exponent 65535 is too large for 64-bit type 'long unsigned int'
The exact command I use is :
mdk3 wlp2s0 b -f somefile.txt -a -s 200
(Where wlp2s0 is my main Wi-Fi interface.)
Here is the full logs:
