| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:H |
Name of the Vulnerable Software and Affected Versions:
Linux kernel (affected versions not specified)
Description:
The Linux kernel TLS implementation does not properly handle situations where data is read from the TCP socket before the TLS ULP is installed, or when non-standard read APIs (like zerocopy) are used. This can lead to undefined behavior within TLS, potentially corrupting streams or causing missed alerts, but should not result in kernel crashes. The issue involves the potential for an out-of-bounds read if insufficient data is present in the socket for a previously parsed record length.
Recommendations:
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
