Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The Linux kernel's keembay crypto driver is affected from version 5.11 until fixed. In an error path where skcipher registration fails, the driver unwinds earlier AEAD registrations using the wrong table size. The source gives few details on who can trigger this or what the impact is. Upgrade to 6.1.191, 6.6.157, 6.12.110, 6.18.52, or a later release in those series.
