high Tenable Self-Hosted Container Security Plugin ID 470454

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: RDMA/mlx4: Fix mis-use of RCU in
mlx4_srq_event() Sashiko points out the radix_tree itself is RCU safe, but nothing ever frees the mlx4_srq
struct with RCU, and it isn't even accessed within the RCU critical section. It also will crash if an
event is delivered before the srq object is finished initializing. Use the spinlock since it isn't easy to
make RCU work, use refcount_inc_not_zero() to protect against partially initialized objects, and order the
refcount_set() to be after the srq is fully initialized. (CVE-2026-46181)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19804.0.0 or later.
