Machine-written summary

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

The Linux kernel svcrdma component is affected from version 6.11, with fixes in 6.12.114, 6.18.57, 7.2.4 and 7.3. A failed listener replacement during an address change leaves a stale pointer, which can cause a use-after-free when the listener is torn down. The source gives few details on what an attacker needs, so upgrade to the fixed release for your branch.
