net: atl1: fix soft lockup on out-of-range cmb_tpd_next_to_clean read

State: Published
Severity: Not scored

Description

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

net: atl1: fix soft lockup on out-of-range cmb_tpd_next_to_clean read

Same issue as atl1c (see the first commit in this series, "net: atl1c: fix soft lockup on out-of-range tpd_cons read"): the hardware can report an out-of-range cmb_tpd_next_to_clean (seen as 0xffff) while the PCIe link/MAC is resetting. An out-of-range value can never be reached and the loop below would spin forever. Treat it as "nothing new to clean" instead.
