CVE-2024-42225: wifi: mt76: replace skb_put with skb_put_zero

Noroxi assessment

Priority: Monitor (action score 30/100)

  • 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: 0.52% (FIRST EPSS).
  • 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: Linux Linux 22ea2a7f0b64d323625950414a4496520fb33657, 64f86337ccfe77fe3be5a9356b0dabde23fbb074, 7f819a2f4fbc510e088b49c79addcf1734503578; azl3 kernel 6.6.35.1-5 on Azure Linux 3.0 6.6.43.1-7; azl3 kernel 6.6.43.1-7 on Azure Linux 3.0 6.6.43.1-7.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 22ea2a7f0b64d323625950414a4496520fb33657, 64f86337ccfe77fe3be5a9356b0dabde23fbb074, 7f819a2f4fbc510e088b49c79addcf1734503578; azl3 kernel 6.6.35.1-5 on Azure Linux 3.0 6.6.43.1-7; azl3 kernel 6.6.43.1-7 on Azure Linux 3.0 6.6.43.1-7 or later.
