In the Linux kernel, the following vulnerability has been resolved:
ipv4: Fix data-races around sysctl_fib_multipath_hash_fields.
While reading sysctl_fib_multipath_hash_fields, it can be changed
concurrently. Thus, we need to add READ_ONCE() to its readers.

CVE-2022-49576 [MEDIUM] CWE-567 kernel: ipv4: Fix data-races around sysctl_fib_multipath_hash_fields.
kernel: ipv4: Fix data-races around sysctl_fib_multipath_hash_fields.
In the Linux kernel, the following vulnerability has been resolved:
ipv4: Fix data-races around sysctl_fib_multipath_hash_fields.
While reading sysctl_fib_multipath_hash_fields, it can be changed
concurrently. Thus, we need to add READ_ONCE() to its readers.
Statement: The bug is only about possibility of value corruption during reading sysctl_fib_multipath_hash_fields (and only if Mellanox Technologies Switch ASICs family hardware being used). No known vector of attack. The security impact is limited.
Mitigation: To mitigate this issue, prevent module mlxsw_core from being loaded. Please see https://access.redhat.com/solutions/41278 for how to blacklist a kernel module to prevent it from loading automatically.
