CVE-2021-0326: In p2p_copy_client_info of p2p.c, there is a possible out of bounds write due to a missing bounds check.
Noroxi assessment
Priority: Monitor (action score 31/100)
- Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
- Probability of exploitation in the next 30 days: 4.9% (FIRST EPSS); higher than 92.2% of all records.
- Someone on the same network segment can trigger it. No account or password is required. No user action is required. Special conditions such as timing or configuration are required.
- Fixed version: wpa_supplicant (Alpine:v3.10) 2.8-r4; wpa_supplicant (Alpine:v3.11) 2.9-r6; wpa_supplicant (Alpine:v3.13) 2.9-r9.
- Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).
Low priority for now. Upgrade to wpa_supplicant (Alpine:v3.10) 2.8-r4; wpa_supplicant (Alpine:v3.11) 2.9-r6; wpa_supplicant (Alpine:v3.13) 2.9-r9 or later.

In p2p_copy_client_info of p2p.c, there is a possible out of bounds write due to a missing bounds check. This could lead to remote code execution if the target device is performing a Wi-Fi Direct search, with no additional execution privileges needed.
