https://notcve.org/view.php?id=CVE-2024-26891
In the Linux kernel, the following vulnerability has been resolved: iommu/vt-d: Don't issue ATS Invalidation request when device is disconnected For those endpoint devices connect to system via hotplug capable ports, users could request a hot reset to the device by flapping device's link through setting the slot's link control register, as pciehp_ist() DLLSC interrupt sequence response, pciehp will unload the device driver and then power it off. thus cause an IOMMU device-TLB invalidation (Intel VT-d spec, or ATS Invalidation in PCIe spec r6.1) request for non-existence target device to be sent and deadly loop to retry that request after ITE fault triggered in interrupt context. That would cause following continuous hard lockup warning and system hang [ 4211.433662] pcieport 0000:17:01.0: pciehp: Slot(108): Link Down [ 4211.433664] pcieport 0000:17:01.0: pciehp: Slot(108): Card not present [ 4223.822591] NMI watchdog: Watchdog detected hard LOCKUP on cpu 144 [ 4223.822622] CPU: 144 PID: 1422 Comm: irq/57-pciehp Kdump: loaded Tainted: G S OE kernel version xxxx [ 4223.822623] Hardware name: vendorname xxxx 666-106, BIOS 01.01.02.03.01 05/15/2023 [ 4223.822623] RIP: 0010:qi_submit_sync+0x2c0/0x490 [ 4223.822624] Code: 48 be 00 00 00 00 00 08 00 00 49 85 74 24 20 0f 95 c1 48 8b 57 10 83 c1 04 83 3c 1a 03 0f 84 a2 01 00 00 49 8b 04 24 8b 70 34 <40> f6 c6 1 0 74 17 49 8b 04 24 8b 80 80 00 00 00 89 c2 d3 fa 41 39 [ 4223.822624] RSP: 0018:ffffc4f074f0bbb8 EFLAGS: 00000093 [ 4223.822625] RAX: ffffc4f040059000 RBX: 0000000000000014 RCX: 0000000000000005 [ 4223.822625] RDX: ffff9f3841315800 RSI: 0000000000000000 RDI: ffff9f38401a8340 [ 4223.822625] RBP: ffff9f38401a8340 R08: ffffc4f074f0bc00 R09: 0000000000000000 [ 4223.822626] R10: 0000000000000010 R11: 0000000000000018 R12: ffff9f384005e200 [ 4223.822626] R13: 0000000000000004 R14: 0000000000000046 R15: 0000000000000004 [ 4223.822626] FS: 0000000000000000(0000) GS:ffffa237ae400000(0000) knlGS:0000000000000000 [ 4223.822627] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 4223.822627] CR2: 00007ffe86515d80 CR3: 000002fd3000a001 CR4: 0000000000770ee0 [ 4223.822627] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 4223.822628] DR3: 0000000000000000 DR6: 00000000fffe07f0 DR7: 0000000000000400 [ 4223.822628] PKRU: 55555554 [ 4223.822628] Call Trace: [ 4223.822628] qi_flush_dev_iotlb+0xb1/0xd0 [ 4223.822628] __dmar_remove_one_dev_info+0x224/0x250 [ 4223.822629] dmar_remove_one_dev_info+0x3e/0x50 [ 4223.822629] intel_iommu_release_device+0x1f/0x30 [ 4223.822629] iommu_release_device+0x33/0x60 [ 4223.822629] iommu_bus_notifier+0x7f/0x90 [ 4223.822630] blocking_notifier_call_chain+0x60/0x90 [ 4223.822630] device_del+0x2e5/0x420 [ 4223.822630] pci_remove_bus_device+0x70/0x110 [ 4223.822630] pciehp_unconfigure_device+0x7c/0x130 [ 4223.822631] pciehp_disable_slot+0x6b/0x100 [ 4223.822631] pciehp_handle_presence_or_link_change+0xd8/0x320 [ 4223.822631] pciehp_ist+0x176/0x180 [ 4223.822631] ? irq_finalize_oneshot.part.50+0x110/0x110 [ 4223.822632] irq_thread_fn+0x19/0x50 [ 4223.822632] irq_thread+0x104/0x190 [ 4223.822632] ? irq_forced_thread_fn+0x90/0x90 [ 4223.822632] ? irq_thread_check_affinity+0xe0/0xe0 [ 4223.822633] kthread+0x114/0x130 [ 4223.822633] ? __kthread_cancel_work+0x40/0x40 [ 4223.822633] ret_from_fork+0x1f/0x30 [ 4223.822633] Kernel panic - not syncing: Hard LOCKUP [ 4223.822634] CPU: 144 PID: 1422 Comm: irq/57-pciehp Kdump: loaded Tainted: G S OE kernel version xxxx [ 4223.822634] Hardware name: vendorname xxxx 666-106, BIOS 01.01.02.03.01 05/15/2023 [ 4223.822634] Call Trace: [ 4223.822634] <NMI> [ 4223.822635] dump_stack+0x6d/0x88 [ 4223.822635] panic+0x101/0x2d0 [ 4223.822635] ? • https://git.kernel.org/stable/c/6f7db75e1c469057fe7588ed959328ead771ccc7 https://git.kernel.org/stable/c/f873b85ec762c5a6abe94a7ddb31df5d3ba07d85 https://git.kernel.org/stable/c/d70f1c85113cd8c2aa8373f491ca5d1b22ec0554 https://git.kernel.org/stable/c/34a7b30f56d30114bf4d436e4dc793afe326fbcf https://git.kernel.org/stable/c/2b74b2a92e524d7c8dec8e02e95ecf18b667c062 https://git.kernel.org/stable/c/c04f2780919f20e2cc4846764221f5e802555868 https://git.kernel.org/stable/c/025bc6b41e020aeb1e71f84ae3ffce945026de05 https://git.kernel.org/stable/c/4fc82cd907ac075648789cc3a00877778 •

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_core: Fix possible buffer overflow struct hci_dev_info has a fixed size name[8] field so in the event that hdev->name is bigger than that strcpy would attempt to write past its size, so this fixes this problem by switching to use strscpy. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Bluetooth: hci_core: soluciona un posible desbordamiento del búfer struct hci_dev_info tiene un campo de nombre de tamaño fijo[8], por lo que en caso de que hdev->name sea mayor que strcpy intentaría escribir más allá su tamaño, por lo que esto soluciona este problema cambiando al uso de strscpy. A buffer overflow flaw was found in struct hci_dev_info in the variable name[8] in the Linkkux Kernel. If an attacker crafts an exploit copying more than the size of the name[8], it results in a buffer overflow and a denial of service. • https://git.kernel.org/stable/c/194ab82c1ea187512ff2f822124bd05b63fc9f76 https://git.kernel.org/stable/c/b48595f5b1c6e81e06e164e7d2b7a30b1776161e https://git.kernel.org/stable/c/ffb060b136dd75a033ced0fc0aed2882c02e8b56 https://git.kernel.org/stable/c/bbec1724519ecd9c468d1186a8f30b7567175bfb https://git.kernel.org/stable/c/a55d53ad5c86aee3f6da50ee73626008997673fa https://git.kernel.org/stable/c/dcda165706b9fbfd685898d46a6749d7d397e0c0 https://git.kernel.org/stable/c/d9ce7d438366431e5688be98d8680336ce0a0f8d https://git.kernel.org/stable/c/5558f4312dca43cebfb9a1aab3d632be9 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-120: Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') •
