Echo: linux: security update to 6.1.153-1

high Tenable Self-Hosted Container Security Plugin ID 455568

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: atm: atmtcp: Prevent arbitrary write
 in atmtcp_recv_control(). syzbot reported the splat below. [0] When atmtcp_v_open() or atmtcp_v_close() is
 called via connect() or close(), atmtcp_send_control() is called to send an in-kernel special message. The
 message has ATMTCP_HDR_MAGIC in atmtcp_control.hdr.length. Also, a pointer of struct atm_vcc is set to
 atmtcp_control.vcc. The notable thing is struct atmtcp_control is uAPI but has a space for an in-kernel
 pointer. struct atmtcp_control { struct atmtcp_hdr hdr; /* must be first */ ... atm_kptr_t vcc; /* both
 directions */ ... } __ATM_API_ALIGN; typedef struct { unsigned char _[8]; } __ATM_API_ALIGN atm_kptr_t;
 The special message is processed in atmtcp_recv_control() called from atmtcp_c_send(). atmtcp_c_send() is
 vcc->dev->ops->send() and called from 2 paths: 1. .ndo_start_xmit() (vcc->send() == atm_send_aal0()) 2.
 vcc_sendmsg() The problem is sendmsg() does not validate the message length and userspace can abuse
 atmtcp_recv_control() to overwrite any kptr by atmtcp_control. Let's add a new ->pre_send() hook to
 validate messages from sendmsg(). [0]: Oops: general protection fault, probably for non-canonical address
