Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
The Linux kernel is affected from 4.17 until fixed in stable releases including 5.10.273, 5.15.224, 6.1.191 and 6.6.160. A user with write access to the tracing files can set up a named histogram trigger with an invalid clock, which leaves freed memory reachable and causes a use-after-free read. Upgrade to a fixed kernel for your branch.
