CVE-2022-50649: power: supply: adp5061: fix out-of-bounds read in adp5061_get_chg_type()

In the Linux kernel, the following vulnerability has been resolved: power: supply: adp5061: fix out-of-bounds read in adp5061_get_chg_type() ADP5061_CHG_STATUS_1_CHG_STATUS is masked with 0x07, which means a length of 8, but adp5061_chg_type array size is 4, may end up reading 4 elements beyond the end of the adp5061_chg_type[] array.

Security readout for executives and security teams

Plain-English summary

CVE-2022-50649 is a Linux kernel bug in the ADP5061 power-supply charger driver. A status value can index past a small array, causing an out-of-bounds read. Business urgency is mainly for Linux-based devices that include this hardware/driver. No active exploitation is indicated in the provided sources.

Executive priority

Treat as targeted kernel maintenance, not an emergency based on current evidence. Prioritize products and embedded devices where battery-charging hardware is part of the platform, and fold remediation into the next tested kernel update cycle unless your vendor rates it higher.

Technical view

The issue is in adp5061_get_chg_type(). ADP5061_CHG_STATUS_1_CHG_STATUS is masked to three bits, allowing values 0-7, while adp5061_chg_type has four entries. Values 4-7 can read beyond the array. Linux stable commits are referenced as fixes; CVSS and CWE are not provided.

Likely exposure

Exposure appears limited to Linux kernels with the ADP5061 power-supply driver present and reachable on relevant hardware. General-purpose Linux servers without this charger component are less likely to be exposed, but kernel configuration and device inventory should confirm this.

Exploitation context

The source bundle does not provide exploit prerequisites, impact beyond out-of-bounds read, or proof of exploitation. CISA KEV status is false in the bundle, so active exploitation should not be assumed.

Researcher notes

The record names Linux as affected and lists multiple stable commit references. Severity, CVSS, CWE, attack vector, and exploitability details are absent. Analysis should focus on code presence, hardware relevance, and whether downstream vendor kernels have backported the fix.

Mitigation direction

  • Check vendor kernel advisories for CVE-2022-50649 applicability and fixed packages.
  • Update affected Linux kernels to versions containing the referenced stable fixes.
  • Prioritize embedded, mobile, or appliance fleets using ADP5061 charging hardware.
  • If patching is delayed, consult vendor guidance for safe compensating controls.

Validation and detection

  • Inventory devices running Linux kernels in the affected version range from the CVE record.
  • Confirm whether the ADP5061 power-supply driver is built, loaded, or used.
  • Compare kernel source or package changelog against the referenced stable commits.
  • Track remediation through normal kernel package deployment evidence.
