What it actually does
Use-after-free in mlx5_debug_cq_remove when mlx5_core_destroy_cq fails to nullify cq->dbg, allowing repeated calls to dereference an invalid pointer and trigger general protection fault during debugfs operations.
Why it matters to the business
Unexpected system crashes and instability on systems using mlx5 network hardware, increasing downtime risk and operational overhead with no known active exploitation or ransomware use.
How an attack unfolds
Attacker triggers a failing MLX5_CMD_OP_DESTROY_CQ command, then re-invokes the destroy path so that mlx5_debug_cq_remove operates on a stale cq->dbg pointer, resulting in a kernel fault during lockref_get or simple_recursive_removal.
How to fix it
Apply the fix that nullifies cq->dbg after removal and only proceeds with destroy operations on FW success (commit 0fad1ccfe9dd7a3c5b82c1496df3c2b4842870d3 in rubygems/rubygems). Rebuild and deploy updated kernel packages.
How to confirm the fix worked
Confirm absence of the vulnerable mlx5_debug_cq_remove logic in source, reproduce the double-destroy path in a test environment, and verify no crash occurs; check kernel version against the published fix date.
Typical attack path
- Cause mlx5_core_destroy_cq to return non-zero status
- Re-issue uverbs destroy command on the same CQ object
- mlx5_debug_cq_remove dereferences non-nullified dbg pointer
- Kernel hits general protection fault in lockref_get
How to detect it
Search kernel logs and oops reports for strings referencing mlx5_debug_cq_remove, mlx5_core_destroy_cq, lockref_get, or general protection fault with non-canonical addresses; correlate with ib_uverbs ioctl activity.
- mlx5_debug_cq_remove+0x32/0x70
- general protection fault, probably for non-canonical address
- lockref_get+0x1/0x60
- devx_obj_cleanup
- MLX5_CMD_OP_DESTROY_CQ
What your security team should do
- Prioritize patching mlx5 driver code in all affected kernels within normal maintenance windows
- Monitor kernel logs for general protection faults involving mlx5_core or debugfs_remove
- Test network device reset and CQ cleanup paths under failure injection
The record
In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: nullify cq->dbg pointer in mlx5_debug_cq_remove() Prior to this patch in case mlx5_core_destroy_cq() failed it proceeds to rest of destroy operations. mlx5_core_destroy_cq() could be called again by user and cause additional call of mlx5_debug_cq_remove(). cq->dbg was not nullify in previous call and cause the crash. Fix it by nullify cq->dbg pointer after removal. Also proceed to destroy operations only if FW return 0 for MLX5_CMD_OP_DESTROY_CQ command. general protection fault, probably for non-canonical address 0x2000300004058: 0000 [#1] SMP PTI CPU: 5 PID: 1228 Comm: python Not tainted 5.15.0-rc5_for_upstream_min_debug_2021_10_14_11_06 #1 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), BIOS rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org 04/01/2014 RIP: 0010:lockref_get+0x1/0x60 Code: 5d e9 53 ff ff ff 48 8d 7f 70 e8 0a 2e 48 00 c7 85 d0 00 00 00 02 00 00 00 c6 45 70 00 fb 5d c3 c3 cc cc cc cc cc cc cc cc 53 <48> 8b 17 48 89 fb 85 d2 75 3d 48 89 d0 bf 64 00 00 00 48 89 c1 48 RSP: 0018:ffff888137dd7a38 EFLAGS: 00010206 RAX: 0000000000000000 RBX: ffff888107d5f458 RCX: 00000000fffffffe RDX: 000000000002c2b0 RSI: ffffffff8155e2e0 RDI: 0002000300004058 RBP: ffff888137dd7a88 R08: 0002000300004058 R09: ffff8881144a9f88 R10: 0000000000000000 R11: 0000000000000000 R12: ffff8881141d4000 R13: ffff888137dd7c68 R14: ffff888137dd7d58 R15: ffff888137dd7cc0 FS: 00007f4644f2a4c0(0000) GS:ffff8887a2d40000(0000) knlGS:0000000000000000 CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 CR2: 000055b4500f4380 CR3: 0000000114f7a003 CR4: 0000000000170ea0 Call Trace: simple_recursive_removal+0x33/0x2e0 ? debugfs_remove+0x60/0x60 debugfs_remove+0x40/0x60 mlx5_debug_cq_remove+0x32/0x70 [mlx5_core] mlx5_core_destroy_cq+0x41/0x1d0 [mlx5_core] devx_obj_cleanup+0x151/0x330 [mlx5_ib] ? __pollwait+0xd0/0xd0 ? xas_load+0x5/0x70 ? xa_load+0x62/0xa0 destroy_hw_idr_uobject+0x20/0x80 [ib_uverbs] uverbs_destroy_uobject+0x3b/0x360 [ib_uverbs] uobj_destroy+0x54/0xa0 [ib_uverbs] ib_uverbs_cmd_verbs+0xaf2/0x1160 [ib_uverbs] ? uverbs_finalize_object+0xd0/0xd0 [ib_uverbs] ib_uverbs_ioctl+0xc4/0x1b0 [ib_uverbs] __x64_sys_ioctl+0x3e4/0x8e0
