That helper acquires the Ethernet subsystem\nhardware lock via lan743x_hs_syslock_acquire(), which relies on\nadapter->eth_syslock_spinlock to serialize access.\n\nThe spinlock is currently initialized only after the strap status is\nread. With CONFIG_DEBUG_SPINLOCK enabled, taking the zeroed initialized\nspinlock can trip the spinlock debug check.\n\nFix by initializing adapter->eth_syslock_spinlock before reading the\nstrap status so the probe path never attempts to lock an uninitialized\nspinlock.","published":"2026-08-15T06:21:13.000Z","lastModified":"2026-08-17T06:18:02.000Z","status":"Received","sourceIdentifier":"416baaa9-dc9f-4396-8d5f-8c081fb06d67","cvss":null,"cwe":[],"affected":[],"epss":{"score":0.00215,"percentile":0.11743,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"unknown","text":"Not yet scored.
