CVE-2022-49572 Details
Description
In the Linux kernel, the following vulnerability has been resolved: tcp: Fix data-races around sysctl_tcp_slow_start_after_idle. While reading sysctl_tcp_slow_start_after_idle, it can be changed concurrently. Thus, we need to add READ_ONCE() to its readers.
A data-race vulnerability has been identified in the Linux kernel's TCP implementation, specifically concerning the sysctl_tcp_slow_start_after_idle parameter. This vulnerability arises because the parameter can be modified concurrently while it is being read, leading to potential inconsistencies. The issue has been addressed by adding a READ_ONCE() directive to the readers of this parameter.
