CVE-2026-72182: power: supply: charger-manager: fix refcount leak in is_full_charged()

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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).
  • Fixed version: Linux Linux 193e6471e985c2f25d09b3fe96ec52f4eab89bd4, 3999f47e4bbf864e3c7fbfd813fb2f651e6b5714, 4373cfa38ead58f980362c841b0d0bdf8c4d956c.

Low priority for now. Upgrade to Linux Linux 193e6471e985c2f25d09b3fe96ec52f4eab89bd4, 3999f47e4bbf864e3c7fbfd813fb2f651e6b5714, 4373cfa38ead58f980362c841b0d0bdf8c4d956c 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: power: supply: charger-manager: fix refcount leak in is_full_charged() In is_full_charged(), power_supply_get_by_name() is called to obtain a reference to the fuel_gauge power supply. If the voltage check (uV >= desc->fullbatt_uV) succeeds, the function returns true directly without releasing the reference, leaking the refcount. Fix this by setting a flag and jumping to the out label where power_supply_put() properly drops the reference.
