kernel: veth: Fix use after free in XDP_REDIRECT

A use-after-free vulnerability has been identified within the vethconvertskbtoxdpbuff function of the Linux kernel's veth driver. The flaw stems from improper memory management during packet headroom expansion for XDP eXpress Data Path. Specifically, when the pskbexpandhead function allocates new...

kernel: network backend may cause Linux netfront to use freed SKBs (XSA-405)

An incomplete cleanup flaw was found in the Linux kernel’s Xen networking XDP eXpress Data Path subsystem. This flaw allows a local user to crash the system...

kernel: xsk: Fix race at socket teardown

A flaw was found in the Linux kernel's XDP socket support. A race condition in the XSK socket cleanup can cause a NULL pointer dereference and result in a denial of service...
