"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: lan743x: fix potential out-of-bounds write in lan743x_ptp_io_event_clock_get()\n\nBefore calling lan743x_ptp_io_event_clock_get(), the 'channel' value\nis checked against the maximum value of PCI11X1X_PTP_IO_MAX_CHANNELS(8).\nThis seems correct and aligns with the PTP interrupt status register\n(PTP_INT_STS) specifications.\n\nHowever, lan743x_ptp_io_event_clock_get() writes to ptp->extts[] with\nonly LAN743X_PTP_N_EXTTS(4) elements, using channel as an index:\n\n lan743x_ptp_io_event_clock_get(..., u8 channel,...)\n {\n ...\n /* Update Local timestamp */\n extts = &ptp->extts[channel];\n extts->ts.tv_sec = sec;\n ...\n }\n\nTo avoid an out-of-bounds write and utilize all the supported GPIO\ninputs, set LAN743X_PTP_N_EXTTS to 8.\n\nDetected using the static analysis tool - Svace."
