CVE-2023-52525: wifi: mwifiex: Fix oob check condition in mwifiex_process_rx_packet

HighCVSS 7.1 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 28/100)

  • 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: 0.23% (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 10a18c8bac7f60d32b7af22da03b66f350beee38, 16cc18b9080892d1a0200a38e36ae52e464bc555, 4.14.327.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 10a18c8bac7f60d32b7af22da03b66f350beee38, 16cc18b9080892d1a0200a38e36ae52e464bc555, 4.14.327 or later.

In the Linux kernel, the following vulnerability has been resolved: wifi: mwifiex: Fix oob check condition in mwifiex_process_rx_packet Only skip the code path trying to access the rfc1042 headers when the buffer is too small, so the driver can still process packets without rfc1042 headers.
