medium Tenable Self-Hosted Container Security Plugin ID 464342

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: iavf: fix off-by-one issues in
 iavf_config_rss_reg() There are off-by-one bugs when configuring RSS hash key and lookup table, causing
 out-of-bounds reads to memory [1] and out-of-bounds writes to device registers. Before commit 43a3d9ba34c9
 ("i40evf: Allow PF driver to configure RSS"), the loop upper bounds were: i <=
 I40E_VFQF_{HKEY,HLUT}_MAX_INDEX which is safe since the value is the last valid index. That commit changed
 the bounds to: i <= adapter->rss_{key,lut}_size / 4 where `rss_{key,lut}_size / 4` is the number of
 dwords, so the last valid index is `(rss_{key,lut}_size / 4) - 1`. Therefore, using `<=` accesses one
 element past the end. Fix the issues by using `<` instead of `<=`, ensuring we do not exceed the bounds.
