CVE-2026-72060

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

net: ethernet: ti: icssg: guard PA stat lookups

icssgndogetstats64() unconditionally calls emacgetstatbyname() with FW PA stat names regardless of whether the PA stats block is present on the hardware. emacgetstatbyname() already guards the PA stats lookup with if (emac->prueth->pa_stats); when that pointer is NULL the lookup falls through to netdeverr() and returns -EINVAL. Because ndogetstats64 is polled regularly by the networking stack this produces thousands of log entries of the form:

icssg-prueth icssg1-eth end0: Invalid stats FWRXERROR

A secondary consequence is that the int(-EINVAL) return value is implicitly widened to a near-ULLONG_MAX unsigned value when accumulated into the _u64 fields of rtnllinkstats64, silently corrupting the rxerrors, rxdropped and txdropped counters reported by ip -s link.

Every other PA-aware code path in the driver is already guarded with the same if (emac->prueth->pa_stats) check. Apply the same guard here.
