Ricardo RobainaandGreg Kroah-Hartman e82735d5d3 audit: fix potential integer overflow in audit_log_n_hex() ...

[ Upstream commit 65dfde57d1 ]

The function calculates new_len as len << 1 for hex encoding. This
has two overflow risks: the shift itself can overflow when len is
large, and the result can be truncated when assigned to new_len
(declared as int) from the size_t calculation.

Fix by using check_shl_overflow() to catch shift overflow and
changing new_len and loop counter i to size_t to prevent truncation.
