Vulnerability from github – Published: 2024-07-12 15:31 – Updated: 2024-08-06 15:30In the Linux kernel, the following vulnerability has been resolved:
ocfs2: fix NULL pointer dereference in ocfs2_abort_trigger()
bdev->bd_super has been removed and commit 8887b94d9322 change the usage from bdev->bd_super to b_assoc_map->host->i_sb. Since ocfs2 hasn't set bh->b_assoc_map, it will trigger NULL pointer dereference when calling into ocfs2_abort_trigger().
Actually this was pointed out in history, see commit 74e364ad1b13. But I've made a mistake when reviewing commit 8887b94d9322 and then re-introduce this regression.
Since we cannot revive bdev in buffer head, so fix this issue by initializing all types of ocfs2 triggers when fill super, and then get the specific ocfs2 trigger from ocfs2_caching_info when access journal.

GHSA-86MQ-WJ5H-4FR6
Vulnerability from github – Published: 2026-05-21 15:34 – Updated: 2026-06-26 18:33In the Linux kernel, the following vulnerability has been resolved:
net/sched: sch_red: Replace direct dequeue call with peek and qdisc_dequeue_peeked
When red qdisc has children (eg qfq qdisc) whose peek() callback is qdisc_peek_dequeued(), we could get a kernel panic. When the parent of such qdiscs (eg illustrated in patch #3 as tbf) wants to retrieve an skb from its child (red in this case), it will do the following: 1a. do a peek() - and when sensing there's an skb the child can offer, then - the child in this case(red) calls its child's (qfq) peek. qfq does the right thing and will return the gso_skb queue packet. Note: if there wasnt a gso_skb entry then qfq will store it there. 1b. invoke a dequeue() on the child (red). And herein lies the problem. - red will call the child's dequeue() which will essentially just try to grab something of qfq's queue.

The right thing to do in #1b is to grab the skb off gso_skb queue. This patchset fixes that issue by changing #1b to use qdisc_dequeue_peeked() method instead.

"details": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sched: sch_red: Replace direct dequeue call with peek and qdisc_dequeue_peeked\n\nWhen red qdisc has children (eg qfq qdisc) whose peek() callback is\nqdisc_peek_dequeued(), we could get a kernel panic. When the parent of such\nqdiscs (eg illustrated in patch #3 as tbf) wants to retrieve an skb from\nits child (red in this case), it will do the following:\n 1a. do a peek() - and when sensing there\u0027s an skb the child can offer, then\n - the child in this case(red) calls its child\u0027s (qfq) peek.\n qfq does the right thing and will return the gso_skb queue packet.\n Note: if there wasnt a gso_skb entry then qfq will store it there.\n 1b. invoke a dequeue() on the child (red). And herein lies the problem.\n - red will call the child\u0027s dequeue() which will essentially just\n try to grab something of qfq\u0027s queue.\n\n[ 78.667668][ T363] KASAN: null-ptr-deref in range [0x0000000000000048-0x000000000000004f]\n[ 78.667927][ T363] CPU: 1 UID: 0 PID: 363 Comm: ping Not tainted 7.1.0-rc1-00033-g46f74a3f7d57-dirty #790 PREEMPT(full)\n[ 78.668263][ T363] Hardware name: Bochs Bochs, BIOS Bochs 01/01/2011\n[ 78.668486][ T363] RIP: 0010:qfq_dequeue+0x446/0xc90 [sch_qfq]\n[ 78.668718][ T363] Code: 54 c0 e8 dd 90 00 f1 48 c7 c7 e0 03 54 c0 48 89 de e8 ce 90 00 f1 48 8d 7b 48 b8 ff ff 37 00 48 89 fa 48 c1 e0 2a 48 c1 ea 03 \u003c80\u003e 3c 02 00 74 05 e8 ef a1 e1 f1 48 8b 7b 48 48 8d 54 24 58 48 8d\n[ 78.669312][ T363] RSP: 0018:ffff88810de573e0 EFLAGS: 00010216\n[ 78.669533][ T363] RAX: dffffc0000000000 RBX: 0000000000000000 RCX: 0000000000000000\n[ 78.669790][ T363] RDX: 0000000000000009 RSI: 0000000000000004 RDI: 0000000000000048\n[ 78.670044][ T363] RBP: ffff888110dc4000 R08: ffffffffb1b0885a R09: fffffbfff6ba9078\n[ 78.670297][ T363] R10: 0000000000000003 R11: ffff888110e31c80 R12: 0000001880000000\n[ 78.670560][ T363] R13: ffff888110dc4150 R14: ffff888110dc42b8 R15: 0000000000000200\n[ 78.670814][ T363] FS: 00007f66a8f09c40(0000) GS:ffff888163428000(0000) knlGS:0000000000000000\n[ 78.671110][ T363] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n[ 78.671324][ T363] CR2: 000055db4c6a30a8 CR3: 000000010da67000 CR4: 0000000000750ef0\n[ 78.671585][ T363] PKRU: 55555554\n[ 78.671713][ T363] Call Trace:\n[ 78.671843][ T363] \u003cTASK\u003e\n[ 78.671936][ T363] ? __pfx_qfq_dequeue+0x10/0x10 [sch_qfq]\n[ 78.672148][ T363] ? __pfx__printk+0x10/0x10\n[ 78.672322][ T363] ? srso_alias_return_thunk+0x5/0xfbef5\n[ 78.672496][ T363] ? lockdep_hardirqs_on_prepare+0xa8/0x1a0\n[ 78.672706][ T363] ? srso_alias_return_thunk+0x5/0xfbef5\n[ 78.672875][ T363] ? trace_hardirqs_on+0x19/0x1a0\n[ 78.673047][ T363] red_dequeue+0x65/0x270 [sch_red]\n[ 78.673217][ T363] ? srso_alias_return_thunk+0x5/0xfbef5\n[ 78.673385][ T363] tbf_dequeue.cold+0xb0/0x70c [sch_tbf]\n[ 78.673566][ T363] __qdisc_run+0x169/0x1900\n\nThe right thing to do in #1b is to grab the skb off gso_skb queue.\nThis patchset fixes that issue by changing #1b to use qdisc_dequeue_peeked()\nmethod instead.",

Mitigation MIT-56
For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].
Mitigation
Select a programming language that is not susceptible to these issues.
Mitigation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.
Mitigation
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
No CAPEC attack patterns related to this CWE.
