UBUNTU-CVE-2024-50008: Low severity ubuntu/linux-aws vulnerability

Q: Which systems are realistically exposed?

Systems running an affected Ubuntu kernel package and using the Marvell mwifiex wireless driver are the relevant exposure set. The issue is in the driver's extended scan command handling.

Q: What level of access does an attacker need?

The supplied vector indicates local access, low attack complexity, required low privileges, no user interaction, and that the attacker must satisfy an additional attack requirement. It does not indicate a network-only attack path.

Q: What is the practical impact?

The vector indicates low availability impact and no impact to confidentiality or integrity. The reported behavior is a kernel field-spanning memcpy write warning during extended Wi-Fi scanning.

Q: How can I tell whether I may be affected?

Kernel logs may show a memcpy field-spanning write warning in mwifiex_cmd_802_11_scan_ext(), referencing drivers/net/wireless/marvell/mwifiex/scan.c and the ext_scan->tlv_buffer field. This indicates the affected code path was reached.

Frequently Asked Questions

Which systems are realistically exposed?

Systems running an affected Ubuntu kernel package and using the Marvell mwifiex wireless driver are the relevant exposure set. The issue is in the driver's extended scan command handling.

What level of access does an attacker need?

The supplied vector indicates local access, low attack complexity, required low privileges, no user interaction, and that the attacker must satisfy an additional attack requirement. It does not indicate a network-only attack path.

What is the practical impact?

The vector indicates low availability impact and no impact to confidentiality or integrity. The reported behavior is a kernel field-spanning memcpy write warning during extended Wi-Fi scanning.

How can I tell whether I may be affected?

Kernel logs may show a memcpy field-spanning write warning in mwifiex_cmd_802_11_scan_ext(), referencing drivers/net/wireless/marvell/mwifiex/scan.c and the ext_scan->tlv_buffer field. This indicates the affected code path was reached.
