CVE-2026-45902
Description
A flaw was found in the Linux kernel's bq256xx power supply driver. A race condition during device removal or probing can lead to a use-after-free vulnerability. This occurs when an interrupt handler attempts to access a power supply handle that has already been freed or is uninitialized. A local attacker could potentially exploit this to cause system instability or crashes, leading to a denial of service.
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.
