In the Linux kernel, the following vulnerability has been resolved:
net: systemport: Fix buffer overflow in bcm_sysport_get_stats()
When running on SYSTEMPORT Lite, certain statistics are unsupported and
skipped during bcm_sysport_get_stats(). The variable 'j' tracks the
compacted index into the destination data buffer, whereas 'i' iterates
over all elements in bcm_sysport_gstrings_stats.
Because the buffer allocated by ethtool is sized only according to
bcm_sysport_get_sset_count(), storing values at data[i] instead of
data[j] writes past the allocated array bounds, leading to memory
corruption.
Fix this by writing to data[j] instead of data[i].
