net/sched: ets: Always remove class from active list before deleting in ets_qdisc_change

Summary

In the Linux kernel, the following vulnerability has been resolved: net/sched: ets: Always remove class from active list before deleting in ets_qdisc_change zdi-disclosures@trendmicro.com says: The vulnerability is a race condition between `ets_qdisc_dequeue` and `ets_qdisc_change`. It leads to UAF on `struct Qdisc` object. Attacker requires the capability to create new user and network namespace in order to trigger the bug. See my additional commentary at the end of the analysis. Analysis: static int ets_qdisc_change(struct Qdisc *sch, struct nlattr *opt, struct netlink_ext_ack *extack) { ... // (1) this lock is preventing .change handler (`ets_qdisc_change`) //to race with .dequeue handler (`ets_qdisc_dequeue`) sch_tree_lock(sch); for (i = nbands; i < oldbands; i++) { if (i >= q->nstrict && q->classes[i].qdisc->q.qlen) list_del_init(&q->classes[i].alist); qdisc_purge_queue(q->classes[i].qdisc); } WRITE_ONCE(q->nbands, nbands); for (i = nstrict; i < q->nstrict; i++) { if (q->classes[i].qdisc->q.qlen) { // (2) the class is added to the q->active list_add_tail(&q->classes[i].alist, &q->active); q->classes[i].deficit = quanta[i]; } } WRITE_ONCE(q->nstrict, nstrict); memcpy(q->prio2band, priomap, sizeof(priomap)); for (i = 0; i < q->nbands; i++) WRITE_ONCE(q->classes[i].quantum, quanta[i]); for (i = oldbands; i < q->nbands; i++) { q->classes[i].qdisc = queues[i]; if (q->classes[i].qdisc != &noop_qdisc) qdisc_hash_add(q->classes[i].qdisc, true); } // (3) the qdisc is unlocked, now dequeue can be called in parallel // to the rest of .change handler sch_tree_unlock(sch); ets_offload_change(sch); for (i = q->nbands; i < oldbands; i++) { // (4) we're reducing the refcount for our class's qdisc and // freeing it qdisc_put(q->classes[i].qdisc); // (5) If we call .dequeue between (4) and (5), we will have // a strong UAF and we can control RIP q->classes[i].qdisc = NULL; WRITE_ONCE(q->classes[i].quantum, 0); q->classes[i].deficit = 0; gnet_stats_basic_sync_init(&q->classes[i].bstats); memset(&q->classes[i].qstats, 0, sizeof(q->classes[i].qstats)); } return 0; } Comment: This happens because some of the classes have their qdiscs assigned to NULL, but remain in the active list. This commit fixes this issue by always removing the class from the active list before deleting and freeing its associated qdisc Reproducer Steps (trimmed version of what was sent by zdi-disclosures@trendmicro.com) ``` DEV="${DEV:-lo}" ROOT_HANDLE="${ROOT_HANDLE:-1:}" BAND2_HANDLE="${BAND2_HANDLE:-20:}" # child under 1:2 PING_BYTES="${PING_BYTES:-48}" PING_COUNT="${PING_COUNT:-200000}" PING_DST="${PING_DST:-127.0.0.1}" SLOW_TBF_RATE="${SLOW_TBF_RATE:-8bit}" SLOW_TBF_BURST="${SLOW_TBF_BURST:-100b}" SLOW_TBF_LAT="${SLOW_TBF_LAT:-1s}" cleanup() { tc qdisc del dev "$DEV" root 2>/dev/null } trap cleanup EXIT ip link set "$DEV" up tc qdisc del dev "$DEV" root 2>/dev/null || true tc qdisc add dev "$DEV" root handle "$ROOT_HANDLE" ets bands 2 strict 2 tc qdisc add dev "$DEV" parent 1:2 handle "$BAND2_HANDLE" \ tbf rate "$SLOW_TBF_RATE" burst "$SLOW_TBF_BURST" latency "$SLOW_TBF_LAT" tc filter add dev "$DEV" parent 1: protocol all prio 1 u32 match u32 0 0 flowid 1:2 tc -s qdisc ls dev $DEV ping -I "$DEV" -f -c "$PING_COUNT" -s "$PING_BYTES" -W 0.001 "$PING_DST" \ >/dev/null 2>&1 & tc qdisc change dev "$DEV" root handle "$ROOT_HANDLE" ets bands 2 strict 0 tc qdisc change dev "$DEV" root handle "$ROOT_HANDLE" ets bands 2 strict 2 tc -s qdisc ls dev $DEV tc qdisc del dev "$DEV" parent ---truncated---

CVE-2025-71071 (GCVE-0-2025-71071)

Vulnerability from cvelistv5 – Published: 2026-01-13 15:31 – Updated: 2026-05-23 16:03

Title

iommu/mediatek: fix use-after-free on probe deferral

Summary

In the Linux kernel, the following vulnerability has been resolved: iommu/mediatek: fix use-after-free on probe deferral The driver is dropping the references taken to the larb devices during probe after successful lookup as well as on errors. This can potentially lead to a use-after-free in case a larb device has not yet been bound to its driver so that the iommu driver probe defers. Fix this by keeping the references as expected while the iommu driver is bound.

Severity

CVE-2025-71104 (GCVE-0-2025-71104)

Title

KVM: x86: Fix VM hard lockup after prolonged inactivity with periodic HV timer

Summary

In the Linux kernel, the following vulnerability has been resolved: KVM: x86: Fix VM hard lockup after prolonged inactivity with periodic HV timer When advancing the target expiration for the guest's APIC timer in periodic mode, set the expiration to "now" if the target expiration is in the past (similar to what is done in update_target_expiration()). Blindly adding the period to the previous target expiration can result in KVM generating a practically unbounded number of hrtimer IRQs due to programming an expired timer over and over. In extreme scenarios, e.g. if userspace pauses/suspends a VM for an extended duration, this can even cause hard lockups in the host. Currently, the bug only affects Intel CPUs when using the hypervisor timer (HV timer), a.k.a. the VMX preemption timer. Unlike the software timer, a.k.a. hrtimer, which KVM keeps running even on exits to userspace, the HV timer only runs while the guest is active. As a result, if the vCPU does not run for an extended duration, there will be a huge gap between the target expiration and the current time the vCPU resumes running. Because the target expiration is incremented by only one period on each timer expiration, this leads to a series of timer expirations occurring rapidly after the vCPU/VM resumes. More critically, when the vCPU first triggers a periodic HV timer expiration after resuming, advancing the expiration by only one period will result in a target expiration in the past. As a result, the delta may be calculated as a negative value. When the delta is converted into an absolute value (tscdeadline is an unsigned u64), the resulting value can overflow what the HV timer is capable of programming. I.e. the large value will exceed the VMX Preemption Timer's maximum bit width of cpu_preemption_timer_multi + 32, and thus cause KVM to switch from the HV timer to the software timer (hrtimers). After switching to the software timer, periodic timer expiration callbacks may be executed consecutively within a single clock interrupt handler, because hrtimers honors KVM's request for an expiration in the past and immediately re-invokes KVM's callback after reprogramming. And because the interrupt handler runs with IRQs disabled, restarting KVM's hrtimer over and over until the target expiration is advanced to "now" can result in a hard lockup. E.g. the following hard lockup was triggered in the host when running a Windows VM (only relevant because it used the APIC timer in periodic mode) after resuming the VM from a long suspend (in the host). NMI watchdog: Watchdog detected hard LOCKUP on cpu 45 ... RIP: 0010:advance_periodic_target_expiration+0x4d/0x80 [kvm] ...

Since the periodic timer does not require frequent APIC timer register programming, the guest may continue to use the software timer in ---truncated---

          "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nKVM: x86: Fix VM hard lockup after prolonged inactivity with periodic HV timer\n\nWhen advancing the target expiration for the guest\u0027s APIC timer in periodic\nmode, set the expiration to \"now\" if the target expiration is in the past\n(similar to what is done in update_target_expiration()).  Blindly adding\nthe period to the previous target expiration can result in KVM generating\na practically unbounded number of hrtimer IRQs due to programming an\nexpired timer over and over.  In extreme scenarios, e.g. if userspace\npauses/suspends a VM for an extended duration, this can even cause hard\nlockups in the host.\n\nCurrently, the bug only affects Intel CPUs when using the hypervisor timer\n(HV timer), a.k.a. the VMX preemption timer.  Unlike the software timer,\na.k.a. hrtimer, which KVM keeps running even on exits to userspace, the\nHV timer only runs while the guest is active.  As a result, if the vCPU\ndoes not run for an extended duration, there will be a huge gap between\nthe target expiration and the current time the vCPU resumes running.\nBecause the target expiration is incremented by only one period on each\ntimer expiration, this leads to a series of timer expirations occurring\nrapidly after the vCPU/VM resumes.\n\nMore critically, when the vCPU first triggers a periodic HV timer\nexpiration after resuming, advancing the expiration by only one period\nwill result in a target expiration in the past.  As a result, the delta\nmay be calculated as a negative value.  When the delta is converted into\nan absolute value (tscdeadline is an unsigned u64), the resulting value\ncan overflow what the HV timer is capable of programming.  I.e. the large\nvalue will exceed the VMX Preemption Timer\u0027s maximum bit width of\ncpu_preemption_timer_multi + 32, and thus cause KVM to switch from the\nHV timer to the software timer (hrtimers).\n\nAfter switching to the software timer, periodic timer expiration callbacks\nmay be executed consecutively within a single clock interrupt handler,\nbecause hrtimers honors KVM\u0027s request for an expiration in the past and\nimmediately re-invokes KVM\u0027s callback after reprogramming.  And because\nthe interrupt handler runs with IRQs disabled, restarting KVM\u0027s hrtimer\nover and over until the target expiration is advanced to \"now\" can result\nin a hard lockup.\n\nE.g. the following hard lockup was triggered in the host when running a\nWindows VM (only relevant because it used the APIC timer in periodic mode)\nafter resuming the VM from a long suspend (in the host).\n\n  NMI watchdog: Watchdog detected hard LOCKUP on cpu 45\n  ...\n  RIP: 0010:advance_periodic_target_expiration+0x4d/0x80 [kvm]\n  ...\n  RSP: 0018:ff4f88f5d98d8ef0 EFLAGS: 00000046\n  RAX: fff0103f91be678e RBX: fff0103f91be678e RCX: 00843a7d9e127bcc\n  RDX: 0000000000000002 RSI: 0052ca4003697505 RDI: ff440d5bfbdbd500\n  RBP: ff440d5956f99200 R08: ff2ff2a42deb6a84 R09: 000000000002a6c0\n  R10: 0122d794016332b3 R11: 0000000000000000 R12: ff440db1af39cfc0\n  R13: ff440db1af39cfc0 R14: ffffffffc0d4a560 R15: ff440db1af39d0f8\n  FS:  00007f04a6ffd700(0000) GS:ff440db1af380000(0000) knlGS:000000e38a3b8000\n  CS:  0010 DS: 0000 ES: 0000 CR0: 0000000080050033\n  CR2: 000000d5651feff8 CR3: 000000684e038002 CR4: 0000000000773ee0\n  PKRU: 55555554\n  Call Trace:\n   \u003cIRQ\u003e\n   apic_timer_fn+0x31/0x50 [kvm]\n   __hrtimer_run_queues+0x100/0x280\n   hrtimer_interrupt+0x100/0x210\n   ? ttwu_do_wakeup+0x19/0x160\n   smp_apic_timer_interrupt+0x6a/0x130\n   apic_timer_interrupt+0xf/0x20\n   \u003c/IRQ\u003e\n\nMoreover, if the suspend duration of the virtual machine is not long enough\nto trigger a hard lockup in this scenario, since commit 98c25ead5eda\n(\"KVM: VMX: Move preemption timer \u003c=\u003e hrtimer dance to common x86\"), KVM\nwill continue using the software timer until the guest reprograms the APIC\ntimer in some way.

CVE-2025-71113 (GCVE-0-2025-71113)

Vulnerability from cvelistv5 – Published: 2026-01-14 15:05 – Updated: 2026-10-19 18:15

Title

crypto: af_alg - zero initialize memory allocated via sock_kmalloc

Summary

In the Linux kernel, the following vulnerability has been resolved: crypto: af_alg - zero initialize memory allocated via sock_kmalloc Several crypto user API contexts and requests allocated with sock_kmalloc() were left uninitialized, relying on callers to set fields explicitly. This resulted in the use of uninitialized data in certain error paths or when new fields are added in the future. The ACVP patches also contain two user-space interface files: algif_kpp.c and algif_akcipher.c. These too rely on proper initialization of their context structures. A particular issue has been observed with the newly added 'inflight' variable introduced in af_alg_ctx by commit: 67b164a871af ("crypto: af_alg - Disallow multiple in-flight AIO requests") Because the context is not memset to zero after allocation, the inflight variable has contained garbage values. As a result, af_alg_alloc_areq() has incorrectly returned -EBUSY randomly when the garbage value was interpreted as true: https://github.com/gregkh/linux/blame/master/crypto/af_alg.c#L1209 The check directly tests ctx->inflight without explicitly comparing against true/false. Since inflight is only ever set to true or false later, an uninitialized value has triggered -EBUSY failures. Zero-initializing memory allocated with sock_kmalloc() ensures inflight and other fields start in a known state, removing random issues caused by uninitialized data.

This resulted in the use of uninitialized\ndata in certain error paths or when new fields are added in the\nfuture.\n\nThe ACVP patches also contain two user-space interface files:\nalgif_kpp.c and algif_akcipher.c. These too rely on proper\ninitialization of their context structures.\n\nA particular issue has been observed with the newly added\n\u0027inflight\u0027 variable introduced in af_alg_ctx by commit:\n\n  67b164a871af (\"crypto: af_alg - Disallow multiple in-flight AIO requests\")\n\nBecause the context is not memset to zero after allocation,\nthe inflight variable has contained garbage values. As a result,\naf_alg_alloc_areq() has incorrectly returned -EBUSY randomly when\nthe garbage value was interpreted as true:\n\n  https://github.com/gregkh/linux/blame/master/crypto/af_alg.c#L1209\n\nThe check directly tests ctx-\u003einflight without explicitly\ncomparing against true/false. Since inflight is only ever set to\ntrue or false later, an uninitialized value has triggered\n-EBUSY failures. Zero-initializing memory allocated with\nsock_kmalloc() ensures inflight and other fields start in a known\nstate, removing random issues caused by uninitialized data."

Address the issue explicitly avoiding the reinjection in the critical scenario. Note that this is the only fallback critical section that could potentially send packets and hit the double-lock.

CVE-2025-71148 (GCVE-0-2025-71148)

Vulnerability from cvelistv5 – Published: 2026-01-23 14:15 – Updated: 2026-05-11 21:55

Title

net/handshake: restore destructor on submit failure

Summary

In the Linux kernel, the following vulnerability has been resolved: net/handshake: restore destructor on submit failure handshake_req_submit() replaces sk->sk_destruct but never restores it when submission fails before the request is hashed. handshake_sk_destruct() then returns early and the original destructor never runs, leaking the socket. Restore sk_destruct on the error path.

Severity

CVE-2025-71182 (GCVE-0-2025-71182)

Vulnerability from cvelistv5 – Published: 2026-01-31 11:38 – Updated: 2026-10-19 18:15

Title

can: j1939: make j1939_session_activate() fail if device is no longer registered

Summary

In the Linux kernel, the following vulnerability has been resolved: can: j1939: make j1939_session_activate() fail if device is no longer registered syzbot is still reporting unregister_netdevice: waiting for vcan0 to become free. Usage count = 2 even after commit 93a27b5891b8 ("can: j1939: add missing calls in NETDEV_UNREGISTER notification handler") was added. A debug printk() patch found that j1939_session_activate() can succeed even after j1939_cancel_active_session() from j1939_netdev_notify(NETDEV_UNREGISTER) has completed. Since j1939_cancel_active_session() is processed with the session list lock held, checking ndev->reg_state in j1939_session_activate() with the session list lock held can reliably close the race window.

CVE-2025-71184 (GCVE-0-2025-71184)

Vulnerability from cvelistv5 – Published: 2026-01-31 11:38 – Updated: 2026-10-30 12:23

Title

btrfs: fix NULL dereference on root when tracing inode eviction

Summary

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix NULL dereference on root when tracing inode eviction When evicting an inode the first thing we do is to setup tracing for it, which implies fetching the root's id. But in btrfs_evict_inode() the root might be NULL, as implied in the next check that we do in btrfs_evict_inode(). Hence, we either should set the ->root_objectid to 0 in case the root is NULL, or we move tracing setup after checking that the root is not NULL. Setting the rootid to 0 at least gives us the possibility to trace this call even in the case when the root is NULL, so that's the solution taken here.
