{"id":"DEBIAN-CVE-2026-98489","details":"In the Linux kernel, the following vulnerability has been resolved:  net: atl1c: fix soft lockup on out-of-range tpd_cons read  The hardware can report an out-of-range tpd_cons (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. To avoid a soft lockup treat it as \"nothing new to clean\" instead.  Reproduced on two machines, same NIC (Qualcomm Atheros AR8151 v2.0, 4-port), triggered by rebooting a Mikrotik CCR2004 PCIe card that the ports are directly linked to:  - Ubuntu 26.04.1 LTS, kernel 7.0.0-31-generic. The link-flap   precursor, before the lockup was captured with a full trace   elsewhere:      atl1c 0000:05:00.0 enp5s0f0: NETDEV WATCHDOG: CPU: 4: transmit queue 2 timed out 489984 ms     atl1c 0000:05:00.0: MAC state machine can't be idle since disabled for 10ms second     atl1c 0000:05:00.0: atl1c: enp5s0f0 NIC Link is Up\u003c65535 Mbps Full Duplex\u003e    65535 (0xffff) here is the same value tpd_cons reads back once the   loop below gets stuck.  - Proxmox VE, kernel 7.0.14-11-pve. Same NIC/trigger, this time   caught by the soft lockup watchdog with a full stack trace:      watchdog: BUG: soft lockup - CPU#12 stuck for 354s!
