CVE-2023-53022

Summary

CVE-2023-53022: A vulnerability was discovered in the Linux kernel that could lead to a deadlock in the enetic driver's enetic_tx_onestep_tstamp() function. This issue occurs when the netif_tx_lock() is held during an interrupt, allowing the NET_TX softirq to take the lock a second time and cause a deadlock. The vulnerable function runs in process context with softirqs enabled, increasing the likelihood of this occurrence. To mitigate this risk, it is recommended to use netif_tx_lock_bh() instead, which blocks softirqs from running and prevents the deadlock from happening.
