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...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel contains a flaw related to a race condition in the sockmap functionality involving skb socket buffer reference counts. 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...
