CVE-2026-64010
Description
A flaw was found in the Linux kernel's Near Field Communication (NFC) Logical Link Control Protocol (LLCP) connection state machine. A race condition exists where a connection acceptance packet can be processed at the same time a socket is released. This concurrency can lead to a use-after-free vulnerability, allowing a local attacker to potentially achieve privilege escalation.
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.
