CVE-2022-49790: Input: iforce - invert valid length check when fetching device IDs

Noroxi assessment

Priority: Monitor (action score 22/100)

  • 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 24cc679abbf31477d0cc6106ec83c2fbae6b3cdf, 5d53797ce7ce8fb1d95a5bebc5efa9418c4217a3, 6365569d62a75ddf53fb0c2936c16587a365984c.

Low priority for now. Upgrade to Linux Linux 24cc679abbf31477d0cc6106ec83c2fbae6b3cdf, 5d53797ce7ce8fb1d95a5bebc5efa9418c4217a3, 6365569d62a75ddf53fb0c2936c16587a365984c or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: Input: iforce - invert valid length check when fetching device IDs syzbot is reporting uninitialized value at iforce_init_device() [1], for commit 6ac0aec6b0a6 ("Input: iforce - allow callers supply data buffer when fetching device IDs") is checking that valid length is shorter than bytes to read. Since iforce_get_id_packet() stores valid length when returning 0, the caller needs to check that valid length is longer than or equals to bytes to read.
