CVE-2022-50066: net: atlantic: fix aq_vec index out of range error

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 23bf155476539354ab5c8cc9bb460fd1209b39b5, 2ba5e47fb75fbb8fab45f5c1bc8d5c33d8834bd3, 422a02a771599cac96f2b2900d993e0bb7ba5b88.

Low priority for now. Upgrade to Linux Linux 23bf155476539354ab5c8cc9bb460fd1209b39b5, 2ba5e47fb75fbb8fab45f5c1bc8d5c33d8834bd3, 422a02a771599cac96f2b2900d993e0bb7ba5b88 or later.

In the Linux kernel, the following vulnerability has been resolved: net: atlantic: fix aq_vec index out of range error The final update statement of the for loop exceeds the array range, the dereference of self->aq_vec[i] is not checked and then leads to the index out of range error. Also fixed this kind of coding style in other for loop.
