## Overview

In the Linux kernel, the following vulnerability has been resolved:

net: dsa: sja1105: fix kasan out-of-bounds warning in sja1105_table_delete_entry()

There are actually 2 problems:
- deleting the last element doesn't require the memmove of elements
  [i + 1, end) over it. Actually, element i+1 is out of bounds.
- The memmove itself should move size - i - 1 elements, because the last
  element is out of bounds.

The out-of-bounds element still remains out of bounds after being
accessed, so the problem is only that we touch it, not that it becomes
in active use. But I suppose it can lead to issues if the out-of-bounds
element is part of an unmapped page.

## Affected

- `linux_kernel >= 5.2, < 6.14.2`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.14.2`
