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/core: Don't expose hw_counters
outside of init net namespace Commit 467f432a521a ("RDMA/core: Split port and device counter sysfs
attributes") accidentally almost exposed hw counters to non-init net namespaces. It didn't expose them
fully, as an attempt to read any of those counters leads to a crash like this one: [42021.807566] BUG:

[42022.027441] [<ffffffff8780013b>] entry_SYSCALL_64_after_hwframe+0x78/0xe2 The problem can be reproduced
using the following steps: ip netns add foo ip netns exec foo bash cat
/sys/class/infiniband/mlx4_0/hw_counters/* The panic occurs because of casting the device pointer into an
ib_device pointer using container_of() in hw_stat_device_show() is wrong and leads to a memory corruption.
However the real problem is that hw counters should never been exposed outside of the non-init net
namespace. Fix this by saving the index of the corresponding attribute group (it might be 1 or 2 depending
on the presence of driver-specific attributes) and zeroing the pointer to hw_counters group for compat
devices during the initialization. With this fix applied hw_counters are not available in a non-init net
namespace: find /sys/class/infiniband/mlx4_0/ -name hw_counters
/sys/class/infiniband/mlx4_0/ports/1/hw_counters /sys/class/infiniband/mlx4_0/ports/2/hw_counters
/sys/class/infiniband/mlx4_0/hw_counters ip netns add foo ip netns exec foo bash find
/sys/class/infiniband/mlx4_0/ -name hw_counters (CVE-2025-22089)
