CVE-2024-53181: um: vector: Do not use drvdata in release

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.25% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 12f52e373d63f008ee386f371bdd82a3a3779199, 35f8f72b45791a6a71b81140c59d02a6183b6f3b, 376c7f0beb8f6f3800fc3013ef2f422d0cbfbf92.

Low priority for now. Upgrade to Linux Linux 12f52e373d63f008ee386f371bdd82a3a3779199, 35f8f72b45791a6a71b81140c59d02a6183b6f3b, 376c7f0beb8f6f3800fc3013ef2f422d0cbfbf92 or later.

In the Linux kernel, the following vulnerability has been resolved: um: vector: Do not use drvdata in release The drvdata is not available in release. Let's just use container_of() to get the vector_device instance. Otherwise, removing a vector device will result in a crash: RIP: 0033:vector_device_release+0xf/0x50 RSP: 00000000e187bc40 EFLAGS: 00010202 RAX: 0000000060028f61 RBX: 00000000600f1baf RCX: 00000000620074e0 RDX: 000000006220b9c0 RSI: 0000000060551c80 RDI: 0000000000000000 RBP: 00000000e187bc50 R08: 00000000603ad594 R09: 00000000e187bb70 R10: 000000000000135a R11: 00000000603ad422 R12: 00000000623ae028 R13: 000000006287a200 R14: 0000000062006d30 R15: 00000000623700b6 Kernel panic - not syncing: Segfault with no mm CPU: 0 UID: 0 PID: 16 Comm: kworker/0:1 Not tainted 6.12.0-rc6-g59b723cd2adb #1 Workqueue: events mc_work_proc Stack: 60028f61 623ae028 e187bc80 60276fcd 6220b9c0 603f5820 623ae028 00000000 e187bcb0 603a2bcd 623ae000 62370010 Call Trace: [<60028f61>] ? vector_device_release+0x0/0x50 [<60276fcd>] device_release+0x70/0xba [<603a2bcd>] kobject_put+0xba/0xe7 [<60277265>] put_device+0x19/0x1c [<60281266>] platform_device_put+0x26/0x29 [<60281e5f>] platform_device_unregister+0x2c/0x2e [<60029422>] vector_remove+0x52/0x58 [<60031316>] ? mconsole_reply+0x0/0x50 [<600310c8>] mconsole_remove+0x160/0x1cc [<603b19f4>] ? strlen+0x0/0x15 [<60066611>] ? __dequeue_entity+0x1a9/0x206 [<600666a7>] ? set_next_entity+0x39/0x63 [<6006666e>] ? set_next_entity+0x0/0x63 [<60038fa6>] ? um_set_signals+0x0/0x43 [<6003070c>] mc_work_proc+0x77/0x91 [<60057664>] process_scheduled_works+0x1b3/0x2dd [<60055f32>] ? assign_work+0x0/0x58 [<60057f0a>] worker_thread+0x1e9/0x293 [<6005406f>] ? set_pf_worker+0x0/0x64 [<6005d65d>] ? arch_local_irq_save+0x0/0x2d [<6005d748>] ? kthread_exit+0x0/0x3a [<60057d21>] ? worker_thread+0x0/0x293 [<6005dbf1>] kthread+0x126/0x12b [<600219c5>] new_thread_handler+0x85/0xb6

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

No commit or PR link among the references.

Credits

All researchers

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.

Bug bounty scope

No known public program.

Technical details

Attack conditions

  • Someone with local access to the system can trigger it.
  • A low-privileged account is enough.
