7.8 · HIGHOverview
CVE-2025-38372 is a high-severity vulnerability affecting linux linux_kernel. It was published on July 25, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).
This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.
Technical Description
In the Linux kernel, the following vulnerability has been resolved:
RDMA/mlx5: Fix unsafe xarray access in implicit ODP handling
__xa_store() and __xa_erase() were used without holding the proper lock,
which led to a lockdep warning due to unsafe RCU usage. This patch
replaces them with xa_store() and xa_erase(), which perform the necessary
locking internally.
