Description OSIDB Bzimport 2026-09-17 17:34:10 UTC 
In the Linux kernel, the following vulnerability has been resolved:

wifi: iwlwifi: guard against division by zero in iwl_dbg_tlv_alloc_fragments

Make sure we don't end-up with a num_frags = 0 situation.
For that, check that the required size is not 0 and put a checker on
num_frags as well.
