CVE-2021-47563

A vulnerability was found in the Linux kernel's ice driver, where the addpbleprm function improperly manages the reference counting of the bpfprog object. This issue occurs during the VSI rebuild process, causing a reference count underflow when an old program is mistakenly decremented while stil...

CVE-2021-47563

The Linux kernel contains a vulnerability in the ice driver where bpf_prog refcounting can underflow during a VSI rebuild flow. This occurs because ice_prepare_xdp_rings() passes vsi->xdp_prog as an argument that is later used by ice_vsi_assign_bpf_prog(), causing the same pointers to be swapp...
