  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: systemport: Fix buffer overflow in bcm_sysport_get_stats()\n\nWhen running on SYSTEMPORT Lite, certain statistics are unsupported and\nskipped during bcm_sysport_get_stats(). The variable 'j' tracks the\ncompacted index into the destination data buffer, whereas 'i' iterates\nover all elements in bcm_sysport_gstrings_stats.\n\nBecause the buffer allocated by ethtool is sized only according to\nbcm_sysport_get_sset_count(), storing values at data[i] instead of\ndata[j] writes past the allocated array bounds, leading to memory\ncorruption.\n\nFix this by writing to data[j] instead of data[i].",
