Vulnerability of the efxnicinitinterrupt function in the drivers/net/ethernet/sfc/nic.c module – The Linux kernel’s Ethernet network adapter support driver has a vulnerability where resources are not released after their useful life has ended. Exploiting this vulnerability could allow an attacker...

CVE-2022-50220

In the Linux kernel, the following vulnerability has been resolved: usbnet: Fix linkwatch use-after-free on disconnect usbnet uses the work usbnetdeferredkevent to perform tasks which may sleep. On disconnect, completion of the work was originally awaited in -ndostop. But in 2003, that was moved ...
