CVE-2026-43039
Description
A flaw was found in the Linux kernel's icssg-prueth network driver. This vulnerability allows for information disclosure, where uninitialized kernel memory contents can be exposed to user applications. This occurs because the driver fails to properly copy received packet data into a network buffer before passing it up the system's network stack. This could allow a local user to access sensitive system information.

Availability
Technical Impact: DoS: Crash, Exit, or Restart
The uninitialized resource may contain values that cause program flow to change in ways that the programmer did not intend.
