  "title": "net: systemport: Fix buffer overflow in bcm_sysport_get_stats()",
  "description": "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 \u0027j\u0027 tracks the compacted index into the destination data buffer, whereas \u0027i\u0027 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].",
