[N:linux][PATCH 0/1] netlink: terminate outstanding dump on socket close

[Philip Cox]

CVE-2024-53140

SRU Justification:

[Impact]

A local user can potentially cause a use-after-free by winning a race condition in the netlink code path.

[Backport]
The Fix was cherry-picked from upstream commit 1904fb9ebf911441f90a68e96b22aa73e4410505 


[Test]
compile and boot tested.

[Where problems could occur]
If any back ports are added that assume the old behaviour, it could cause them to fail, but the risk is very low, and the window of change is fairly narrow.
