CVE-2026-98488
In the Linux kernel, the following vulnerability has been resolved: net: atl1e: fix soft lockup on out-of-range hw_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 hw_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.
