Linux Kernel up to 6.12.1 ubd container_of denial of service

CVSS Meta Temp Score CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.	Current Exploit Price (≈) Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.	CTI Interest Score Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability, which was classified as critical, has been found in Linux Kernel up to 6.12.1. This issue affects the function container_of of the component ubd. The manipulation with an unknown input leads to a denial of service vulnerability. Using CWE to declare the problem leads to CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. Impacted is availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: um: ubd: Do not use drvdata in release The drvdata is not available in release. Let's just use container_of() to get the ubd instance. Otherwise, removing a ubd device will result in a crash: RIP: 0033:blk_mq_free_tag_set+0x1f/0xba RSP: 00000000e2083bf0 EFLAGS: 00010246 RAX: 000000006021463a RBX: 0000000000000348 RCX: 0000000062604d00 RDX: 0000000004208060 RSI: 00000000605241a0 RDI: 0000000000000348 RBP: 00000000e2083c10 R08: 0000000062414010 R09: 00000000601603f7 R10: 000000000000133a R11: 000000006038c4bd R12: 0000000000000000 R13: 0000000060213a5c R14: 0000000062405d20 R15: 00000000604f7aa0 Kernel panic - not syncing: Segfault with no mm CPU: 0 PID: 17 Comm: kworker/0:1 Not tainted 6.8.0-rc3-00107-gba3f67c11638 #1 Workqueue: events mc_work_proc Stack: 00000000 604f7ef0 62c5d000 62405d20 e2083c30 6002c776 6002c755 600e47ff e2083c60 6025ffe3 04208060 603d36e0 Call Trace: [] ubd_device_release+0x21/0x55 [] ? ubd_device_release+0x0/0x55 [] ? kfree+0x0/0x100 [] device_release+0x70/0xba [] kobject_put+0xb5/0xe2 [] put_device+0x19/0x1c [] platform_device_put+0x26/0x29 [] platform_device_unregister+0x2c/0x2e [] ubd_remove+0xb8/0xd6 [] ? mconsole_reply+0x0/0x50 [] mconsole_remove+0x160/0x1cc [] ? mconsole_reply+0x48/0x50 [] ? um_set_signals+0x3b/0x43 [] ? update_min_vruntime+0x14/0x70 [] ? dequeue_task_fair+0x164/0x235 [] ? update_cfs_group+0x0/0x40 [] ? __schedule+0x0/0x3ed [] ? um_set_signals+0x0/0x43 [] mc_work_proc+0x77/0x91 [] process_scheduled_works+0x1af/0x2c3 [] ? assign_work+0x0/0x58 [] worker_thread+0x2f7/0x37a [] ? set_pf_worker+0x0/0x64 [] ? arch_local_irq_save+0x0/0x2d [] ? kthread_exit+0x0/0x3a [] ? worker_thread+0x0/0x37a [] kthread+0x130/0x135 [] new_thread_handler+0x85/0xb6
