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...
