CVE-2025-22107

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.
