The mac80211 subsystem in the Linux kernel before 2.6.32-rc8-next-20091201 allows remote attackers to cause a denial of service (panic) via a crafted Delete Block ACK (aka DELBA) packet, related to an erroneous "code shuffling patch."

Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.06%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
