CVE-2022-49594 Details
Description
In the Linux kernel, the following vulnerability has been resolved: tcp: Fix a data-race around sysctl_tcp_mtu_probe_floor. While reading sysctl_tcp_mtu_probe_floor, 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 regarding the sysctl_tcp_mtu_probe_floor parameter. This vulnerability arises because the parameter can be modified concurrently while it is being read, potentially leading to inconsistent or unexpected behavior. The issue has been addressed by adding a READ_ONCE() directive to the parameter's reader, ensuring that changes are properly synchronized and reducing the risk of concurrent modification issues.
