kernel: ip6_vti: fix slab-use-after-free in decode_session6
A use-after-free vulnerability was found in the IPv6 VTI Virtual Tunnel Interface implementation in the Linux kernel. When an IPv6 VTI device uses the SFB Stochastic Fair Blue qdisc, the control block cb field of an skb can be modified during packet enqueuing. The decodesession6 function then rea...
kernel: ipv4: NULL pointer dereference in ipv4_send_dest_unreach()
A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer skb was assumed to be associated with a device before calling ipoptionscompile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAPNETADMIN privileges t...
kernel: bluetooth: bt_sock_ioctl race condition leads to use-after-free in bt_sock_recvmsg
A flaw was found in the Bluetooth subsystem of the Linux kernel. A race condition between the btsockrecvmsg and btsockioctl functions could lead to a use-after-free on a socket buffer "skb". This flaw allows a local user to cause a denial of service condition or potential code execution...

DEBIAN-CVE-2021-47224
In the Linux kernel, the following vulnerability has been resolved: net: lltemac: Make sure to free skb when it is completely used With the skb pointer piggy-backed on the TX BD, we have a simple and efficient way to free the skb buffer when the frame has been transmitted. But in order to avoid...
UBUNTU-CVE-2021-47370
In the Linux kernel, the following vulnerability has been resolved: mptcp: ensure tx skbs always have the MPTCP ext Due to signed/unsigned comparison, the expression: info-sizegoal - skb-len 0 evaluates to true when the size goal is smaller than the skb size. That results in lack of tx cache...
