NewCVE-2026-98394 (opens in a new tab)How to fix?
Upgrade torvalds/linux to version 6.12.111, 6.18.53, 7.2.7 or higher.
Overview
Affected versions of this package are vulnerable to Buffer Overflow in the unix_stream_read_generic process. An attacker can cause the system to enter a busy-wait state by sending a zero-length buffer with the MSG_PEEK flag when the last socket buffer in the queue is marked as out-of-band. This can lead to resource exhaustion and potential denial of service.
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
