NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-tools package and not the kernel-uek-tools package as distributed by Oracle. See How to fix? for Oracle:10 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

net: lan743x: fix potential out-of-bounds write in lan743x_ptp_io_event_clock_get()

Before calling lan743x_ptp_io_event_clock_get(), the 'channel' value is checked against the maximum value of PCI11X1X_PTP_IO_MAX_CHANNELS(8). This seems correct and aligns with the PTP interrupt status register (PTP_INT_STS) specifications.

However, lan743x_ptp_io_event_clock_get() writes to ptp->extts[] with only LAN743X_PTP_N_EXTTS(4) elements, using channel as an index:

lan743x_ptp_io_event_clock_get(..., u8 channel,...)
{
    ...
    /* Update Local timestamp */
    extts = &amp;ptp-&gt;extts[channel];
    extts-&gt;ts.tv_sec = sec;
    ...
}

To avoid an out-of-bounds write and utilize all the supported GPIO inputs, set LAN743X_PTP_N_EXTTS to 8.
