AI Analysis

Impact

The Linux kernel contains an out‑of‑bounds read that occurs when reading the minimum alarm voltage in the ltc4282 driver. This flaw can allow a local attacker to read memory locations beyond the intended buffer, potentially revealing sensitive kernel data. It is tied to an improper bounds check during array access and may lead to information disclosure or kernel corruption.

Affected Systems

All Linux kernel releases that have not yet integrated the patch for the ltc4282 driver are affected. Distributions using the stock kernel prior to the commit that adds the missing return statement are vulnerable.

Risk and Exploitability

The EPSS score is not available and the vulnerability is not listed in the CISA KEV catalog, indicating no public exploitation evidence at this time. An attacker would need local kernel access or the ability to interact with the ltc4282 driver to trigger the out‑of‑bounds read. Because the flaw is a read‑time error, exploitation is likely confined to local privileged users unless elevated privileges can be obtained.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply an updated kernel release that incorporates the ltc4282 fix or back‑port the commit adding the missing return statement from the kernel source tree.
  • If upgrading is not feasible, temporarily disable the ltc4282 driver or unmount its device nodes to prevent the faulty read operation from occurring until a patch can be applied.
  • Use access control mechanisms such as SELinux or AppArmor to restrict non‑privileged users from interacting with the ltc4282 driver files, preventing the vulnerable read from being triggered.
