Use-after-free in Linux kernel - CVE-2026-45882

Vulnerability identifier: #VU132600

CSH Severity: Low

CVSS v4: 5.8 [CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2026-45882

CWE-ID: CWE-416

Exploitation vector: Local access

Exploit availability: No public exploit available

The vulnerability allows a local attacker to cause a denial of service or corrupt memory.

The vulnerability exists due to a use-after-free in the pm8916_bms_vm driver power_supply handling when handling an interrupt during device removal or probe. A local attacker can trigger a race condition to cause a denial of service or corrupt memory.

The issue can also occur if an interrupt fires before the power_supply handle has been registered, leading to use of an uninitialized handle.
