CVE-2022-49598 Details
Description
In the Linux kernel, the following vulnerability has been resolved: tcp: Fix data-races around sysctl_tcp_mtu_probing. While reading sysctl_tcp_mtu_probing, 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 regarding the 'sysctl_tcp_mtu_probing' setting. This vulnerability allows the MTU probing value to be changed concurrently while it is being read, potentially leading to inconsistent behavior. The issue has been addressed by adding a 'READ_ONCE()' directive to the readers of this sysctl parameter.
