Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The Linux kernel mana network driver, from 5.17 until the fixed releases, can drop a fence completion event when the RX completion queue is full, leaving the driver waiting while holding the RTNL lock until a timeout. The source gives few details on what an attacker needs. Upgrade to 6.1.191, 6.6.158, 6.12.111, or 6.18.53 (or a later release in those series), or to a kernel that includes the fix.
