CVE-2026-43232
Description
A flaw was found in the Linux kernel's FarSync WAN driver. A race condition can occur during the detachment of a FarSync T-series card, where already freed memory associated with the card is accessed by unfinished tasks. This use-after-free vulnerability could allow a local attacker to cause a denial of service or potentially execute arbitrary code.
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.
