CVE-2024-53184 Vulnerability Summary

CVE-2024-53184: 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: [<6002c776>] ubd_device_release+0x21/0x55 [<6002c755>] ? ubd_device_release+0x0/0x55 [<600e47ff>] ? kfree+0x0/0x100 [<6025ffe3>] device_release+0x70/0xba [<60381d6a>] kobject_put+0xb5/0xe2 [<6026027b>] put_device+0x19/0x1c [<6026a036>] platform_device_put+0x26/0x29 [<6026ac5a>] platform_device_unregister+0x2c/0x2e [<6002c52e>] ubd_remove+0xb8/0xd6 [<6002bb74>] ? mconsole_reply+0x0/0x50 [<6002b926>] mconsole_remove+0x160/0x1cc [<6002bbbc>] ? mconsole_reply+0x48/0x50 [<6003379c>] ? um_set_signals+0x3b/0x43 [<60061c55>] ? update_min_vruntime+0x14/0x70 [<6006251f>] ? dequeue_task_fair+0x164/0x235 [<600620aa>] ? update_cfs_group+0x0/0x40 [<603a0e77>] ? __schedule+0x0/0x3ed [<60033761>] ? um_set_signals+0x0/0x43 [<6002af6a>] mc_work_proc+0x77/0x91 [<600520b4>] process_scheduled_works+0x1af/0x2c3 [<6004ede3>] ? assign_work+0x0/0x58 [<600527a1>] worker_thread+0x2f7/0x37a [<6004ee3b>] ? set_pf_worker+0x0/0x64 [<6005765d>] ? arch_local_irq_save+0x0/0x2d [<60058e07>] ? kthread_exit+0x0/0x3a [<600524aa>] ? worker_thread+0x0/0x37a [<60058f9f>] kthread+0x130/0x135 [<6002068e>] new_thread_handler+0x85/0xb6

Assessing the Risk of CVE-2024-53184

Access Complexity Graph

The exploitability of CVE-2024-53184 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).

Exploitability Analysis for CVE-2024-53184

No exploitability data is available for CVE-2024-53184.

Understanding AC and PR

A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.

Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.

Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.

CVSS Score Breakdown Chart

Above is the CVSS Sub-score Breakdown for CVE-2024-53184, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.

CIA Impact Analysis

Below is the Impact Analysis for CVE-2024-53184, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
