CVE-2026-46270
Description
A flaw was found in the Linux kernel's power supply driver, specifically in the rt9455 component. This vulnerability, a use-after-free, occurs due to a race condition during the system's shutdown process where an interrupt can access memory that has already been released. This can lead to system instability, including crashes or silent corruption of memory.
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.
