kernel: can: peak_usb: fix use after free bugs
In the Linux kernel, the following vulnerability has been resolved: can: peakusb: fix use after free bugs After calling peakusbnetifrxniskb, dereferencing skb is unsafe. Especially, the canframe cf which aliases skb memory is accessed after the peakusbnetifrxni. Reordering the lines solves the...

Specifically, a race can occur where skbs from the...
kernel: tls: always refresh the queue when reading sock
In the Linux kernel, the following vulnerability has been resolved: tls: always refresh the queue when reading sock After recent changes in net-next TCP compacts skbs much more aggressively. This unearthed a bug in TLS where we may try to operate on an old skb when checking if all skbs in the que...
