CVE-2026-23372
Description
A flaw was found in the Linux kernel's Near Field Communication (NFC) rawsock component. A race condition can occur during the teardown of a socket and its associated device, particularly when a process is terminated (e.g., by SIGKILL). This timing issue can lead to a use-after-free vulnerability, where the system attempts to access memory that has already been released. Such an issue could result in system instability or 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.
