AZL-88875 CVE-2026-46238 affecting package kernel for versions less than 6.6.141.1-1

In the Linux kernel, the following vulnerability has been resolved: batman-adv: stop caching unowned originator pointers in BAT IV BAT IV keeps the last-hop neighbor address in each neighnode, but some paths also cache an originator pointer derived from a temporary lookup. That pointer is not own...

Double-free and use-after-free in `Keys::next()`

Keys::next uses ptr::read to move out the Option by value, which drops the contained V when V is non-Copy e.g. String. This leaves a dangling value in the map's storage slot. Subsequent get operations on that key return a dangling reference to already-freed memory. This can be triggered through...

DynFuture Drop Can Construct a Dangling Reference

DynFuture is unsound because its Drop implementation transmutes a trait-object reference into unrelated reference types, which constructs an invalid reference from trait object metadata. This issue was reproduced against dyn-future 3.0.4 under Miri. The crate is unmaintained...
