LIN1024-9501 : Bug found in sysfsutils sources, for my_strncat function

Created: May 28, 2025 Updated: Jun 16, 2025

Resolved Date: Jun 5, 2025

Found In Version: 10.24.33.8

Fix Version: 10.24.33.10

Severity: Standard

Applicable for: Wind River Linux LTS 24

Component/s: Userspace

Description

The bug was introduced by upstream commit [1] where strncat was replaced with
internal my_strncat function, such as:

  char dest[32] = "/sys/devices/platform/axi";
  my_strncat(dest, "/", sizeof(dest) - strlen(dest) - 1);

Will result in dest string being:

  /sys/

and not the expected:

  /sys/devices/platform/axi/
