CVE-2024-42092: gpio: davinci: Validate the obtained number of IRQs

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: 0.22% (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 2d83492259ad746b655f196cd5d1be4b3d0a3782, 70b48899f3f23f98a52c5b1060aefbdc7ba7957b, 7aa9b96e9a73e4ec1771492d0527bd5fc5ef9164.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to Linux Linux 2d83492259ad746b655f196cd5d1be4b3d0a3782, 70b48899f3f23f98a52c5b1060aefbdc7ba7957b, 7aa9b96e9a73e4ec1771492d0527bd5fc5ef9164 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: gpio: davinci: Validate the obtained number of IRQs Value of pdata->gpio_unbanked is taken from Device Tree. In case of broken DT due to any error this value can be any. Without this value validation there can be out of chips->irqs array boundaries access in davinci_gpio_probe(). Validate the obtained nirq value so that it won't exceed the maximum number of IRQs per bank. Found by Linux Verification Center (linuxtesting.org) with SVACE.
