Overview

Affected versions of this package are vulnerable to Information Exposure in the tcp_write_collapse_fence process. An attacker can access sensitive information by exploiting the merging of encrypted and unencrypted data in the retransmission queue, potentially causing data intended to be encrypted to be sent in cleartext or causing connection stalls.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
