CVE-2022-49574 tcp: Fix data-races around sysctl_tcp_recovery.

In the Linux kernel, the following vulnerability has been resolved: tcp: Fix data-races around sysctltcprecovery. While reading sysctltcprecovery, it can be changed concurrently. Thus, we need to add READONCE to its readers...

CVE-2022-49571

CVE-2022-49571 : In the Linux kernel, a data-race around reading sysctl_tcp_max_reordering could occur as the value is updated concurrently while being read. The fix adds READ_ONCE() to the readers of sysctl_tcp_max_reordering. Affected/affected-by notices appear in multiple advisories (EulerOS, ...

CVE-2022-49572

CVE-2022-49572 affects the Linux kernel tcp path. The issue is a data race around reading the sysctl_tcp_slow_start_after_idle variable, where reads could race with concurrent writes. The published fix adds a READ_ONCE() to the readers to prevent concurrent modification during reads. The vulnerab...

CVE-2022-49330

The CVE-2022-49330 issue affects the Linux kernel's MTU probing logic in net/ipv4/tcp_input.c. Specifically, tcp_mtu_probe() starts an MTU probe only when tcp_snd_cwnd(tp) is >= 11, but tcp_snd_cwnd(tp) can later be reduced before the probe completes, creating a scenario that could lead to a z...
