Bug ID 703848: Possible memory leak when reusing statistics rows in tables

Last Modified: Oct 16, 2023

Affected Product(s):
BIG-IP TMOS(all modules)

Known Affected Versions:
13.0.0, 13.0.0 HF1, 13.0.0 HF2, 13.0.0 HF3, 13.1.0,,,

Fixed In:
14.0.0,, 13.0.1

Opened: Jan 26, 2018

Severity: 3-Major


The handling of the pointers to memory in the statistics tables includes a path that zeros out a pointer to more memory that should be free'd. This means the memory is not free'd for that case.


When slabs are being reused this bug may cause a memory leak.


This condition is usually only hit when the entire file is being deleted and so it doesn't matter that the list is not fully traversed.


There is no workaround at this time.

Fix Information

The code has been fixed to properly follow the list.
