CVE-2024-57910: iio: light: vcnl4035: fix information leak in triggered buffer

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: 0.21% (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 13e56229fc81051a42731046e200493c4a7c28ff, 47b43e53c0a0edf5578d5d12f5fc71c019649279, 47d245be86492974db3aeb048609542167f56518; azl3 kernel 6.6.64.2-9 on Azure Linux 3.0 6.6.76.1-1; cbl2 kernel 5.15.176.3-3 on CBL Mariner 2.0 5.15.180.1-1.

Low priority for now. Upgrade to Linux Linux 13e56229fc81051a42731046e200493c4a7c28ff, 47b43e53c0a0edf5578d5d12f5fc71c019649279, 47d245be86492974db3aeb048609542167f56518; azl3 kernel 6.6.64.2-9 on Azure Linux 3.0 6.6.76.1-1; cbl2 kernel 5.15.176.3-3 on CBL Mariner 2.0 5.15.180.1-1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: iio: light: vcnl4035: fix information leak in triggered buffer The 'buffer' local array is used to push data to userspace from a triggered buffer, but it does not set an initial value for the single data element, which is an u16 aligned to 8 bytes. That leaves at least 4 bytes uninitialized even after writing an integer value with regmap_read(). Initialize the array to zero before using it to avoid pushing uninitialized information to userspace.
