Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> can: hi311x: hi3110_can_ist(): fix potential use-after-free<br /> <br /> The commit a22bd630cfff ("can: hi311x: do not report txerr and rxerr<br /> during bus-off") removed the reporting of rxerr and txerr even in case<br /> of correct operation (i. e. not bus-off).<br /> <br /> The error count information added to the CAN frame after netif_rx() is<br /> a potential use after free, since there is no guarantee that the skb<br /> is in the same state. It might be freed or reused.<br /> <br /> Fix the issue by postponing the netif_rx() call in case of txerr and<br /> rxerr reporting.
