- Summary
- CVE-2025-38460 affecting package kernel for versions less than 5.15.200.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
atm: clip: Fix potential null-ptr-deref in to_atmarpd().
atmarpd is protected by RTNL since commit f3a0592b37b8 ("[ATM]: clip causes unregister hang").
However, it is not enough because toatmarpd() is called without RTNL, especially clipneighsolicit() / neighops->solicit() is unsleepable.
Also, there is no RTNL dependency around atmarpd.
Let's use a private mutex and RCU to protect access to atmarpd in to_atmarpd().
