CVE-2026-45938
Description
A flaw was found in the Linux kernel's pm8916_lbc power supply module. A race condition exists during interrupt handling where an interrupt can fire after the power_supply handle is freed but before the interrupt handler is unregistered. This use-after-free vulnerability can lead to a system crash or silent memory corruption, potentially resulting in a Denial of Service (DoS).
Understanding the Weakness (CWE)
Integrity,Confidentiality,Availability
Technical Impact: Modify Application Data; Modify Memory; DoS: Crash, Exit, or Restart; Execute Unauthorized Code or Commands
It may be possible to cause data corruption and possibly execute arbitrary code by modifying global variables or data structures at unexpected times, violating the assumptions of code that uses this global data.
Access Control
Technical Impact: Gain Privileges or Assume Identity
If a signal handler interrupts code that is executing with privileges, it may be possible that the signal handler will also be executed with elevated privileges, possibly making subsequent exploits more severe.
