CVE-2022-49580 Details
Description
In the Linux kernel, the following vulnerability has been resolved: ipv4: Fix a data-race around sysctl_fib_multipath_use_neigh. While reading sysctl_fib_multipath_use_neigh, it can be changed concurrently. Thus, we need to add READ_ONCE() to its reader.
A data-race vulnerability has been identified in the Linux kernel's IPv4 handling of multipath routing, specifically around the sysctl_fib_multipath_use_neigh parameter. This vulnerability arises because the parameter can be changed concurrently while it is being read, leading to potential inconsistencies. The issue has been addressed by adding a READ_ONCE() directive to the parameter's reader.
