From this webpage screenshot, we can extract the following key information about the vulnerability: 1. Issue Description: - Alexander Sverdlin reported two issues: one specific to the lan9303 driver, and another that also occurs in other DSA drivers. - The lan9303 driver calls during shutdown, which causes it to continue running after shutdown. - The lan9303 driver continues to call after shutdown, leading to continued execution post-shutdown. 2. Solution: - During shutdown, triggers the event, which disables the user port. - calls , which synchronously stops the PHY link state machine. - will no longer be called after shutdown. 3. Code Changes: - Added to ensure that during shutdown, , , and requests are no longer passed down to the driver. - Modified the function to ensure that is set to during shutdown. 4. Fixes Applied: - Fixed the issue: . - Fixed the issue: . 5. Author and Testers: - Author: Alexander Sverdlin. - Testers: Alexander Sverdlin and Vladimir Oltean. This information indicates that two vulnerabilities related to abnormal behavior during shutdown were fixed by triggering specific events during shutdown and modifying code logic.
