CVE-2024-46859: platform/x86: panasonic-laptop: Fix SINF array out of bounds accesses

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: 0.21% (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 6821a82616f60aa72c5909b3e252ad97fb9f7e2a, 9291fadbd2720a869b1d2fcf82305648e2e62a16, b38c19783286a71693c2194ed1b36665168c09c4; Azure Linux 3.0 ARM 6.6.56.1-5; Azure Linux 3.0 x64 6.6.56.1-5.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 6821a82616f60aa72c5909b3e252ad97fb9f7e2a, 9291fadbd2720a869b1d2fcf82305648e2e62a16, b38c19783286a71693c2194ed1b36665168c09c4; Azure Linux 3.0 ARM 6.6.56.1-5; Azure Linux 3.0 x64 6.6.56.1-5 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: platform/x86: panasonic-laptop: Fix SINF array out of bounds accesses The panasonic laptop code in various places uses the SINF array with index values of 0 - SINF_CUR_BRIGHT(0x0d) without checking that the SINF array is big enough. Not all panasonic laptops have this many SINF array entries, for example the Toughbook CF-18 model only has 10 SINF array entries. So it only supports the AC+DC brightness entries and mute. Check that the SINF array has a minimum size which covers all AC+DC brightness entries and refuse to load if the SINF array is smaller. For higher SINF indexes hide the sysfs attributes when the SINF array does not contain an entry for that attribute, avoiding show()/store() accessing the array out of bounds and add bounds checking to the probe() and resume() code accessing these.
