Описание
In the Linux kernel, the following vulnerability has been resolved:
tls: fix race between tx work scheduling and socket close
Similarly to previous commit, the submitting thread (recvmsg/sendmsg)
may exit as soon as the async crypto handler calls complete().
Reorder scheduling the work before calling complete().
This seems more logical in the first place, as it's
the inverse order of what the submitting thread will do.
A race condition vulnerability was found in the tls subsystem of the Linux kernel. The submitting thread (recvmsg/sendmsg) may exit as soon as the async crypto handler calls complete(), which could lead to undefined behavior and a denial of service.
Отчет
Red Hat Enterprise Linux 6 and 7 are not affected by this CVE as they did not include kernel TLS support (upstream commit 3c4d755).
Меры по смягчению последствий
No current mitigation is available for this vulnerability. Please make sure to have kernel up-to-date as soon as the patches are available to make sure the flaw mitigated.
