CVE-2022-49595 Details
Description
In the Linux kernel, the following vulnerability has been resolved: tcp: Fix a data-race around sysctl_tcp_probe_threshold. While reading sysctl_tcp_probe_threshold, 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 TCP implementation, specifically around the sysctl_tcp_probe_threshold 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 reader of the parameter.
