CVSS: 4.4EPSS: 0%CPEs: 8EXPL: 0CVE-2024-36950 – firewire: ohci: mask bus reset interrupts between ISR and bottom half
https://notcve.org/view.php?id=CVE-2024-36950
In the Linux kernel, the following vulnerability has been resolved: firewire: ohci: mask bus reset interrupts between ISR and bottom half In the FireWire OHCI interrupt handler, if a bus reset interrupt has occurred, mask bus reset interrupts until bus_reset_work has serviced and cleared the interrupt. Normally, we always leave bus reset interrupts masked. We infer the bus reset from the self-ID interrupt that happens shortly thereafter. A scenario where we unmask bus reset interrupts was introduced in 2008 in a007bb857e0b26f5d8b73c2ff90782d9c0972620: If OHCI_PARAM_DEBUG_BUSRESETS (8) is set in the debug parameter bitmask, we will unmask bus reset interrupts so we can log them. irq_handler logs the bus reset interrupt. However, we can't clear the bus reset event flag in irq_handler, because we won't service the event until later. irq_handler exits with the event flag still set. If the corresponding interrupt is still unmasked, the first bus reset will usually freeze the system due to irq_handler being called again each time it exits. • https://git.kernel.org/stable/c/b3948c69d60279fce5b2eeda92a07d66296c8130 https://git.kernel.org/stable/c/31279bbca40d2f40cb3bbb6d538ec9620a645dec https://git.kernel.org/stable/c/fa273f312334246c909475c5868e6daab889cc8c https://git.kernel.org/stable/c/4f9cc355c328fc4f41cbd9c4cd58b235184fa420 https://git.kernel.org/stable/c/6fafe3661712b143d9c69a7322294bd53f559d5d https://git.kernel.org/stable/c/5982887de60c1b84f9c0ca07c835814d07fd1da0 https://git.kernel.org/stable/c/8643332aac0576581cfdf01798ea3e4e0d624b61 https://git.kernel.org/stable/c/752e3c53de0fa3b7d817a83050b6699b8 • CWE-99: Improper Control of Resource Identifiers ('Resource Injection') •

https://notcve.org/view.php?id=CVE-2024-36949
In the Linux kernel, the following vulnerability has been resolved: amd/amdkfd: sync all devices to wait all processes being evicted If there are more than one device doing reset in parallel, the first device will call kfd_suspend_all_processes() to evict all processes on all devices, this call takes time to finish. other device will start reset and recover without waiting. if the process has not been evicted before doing recover, it will be restored, then caused page fault. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: amd/amdkfd: sincroniza todos los dispositivos para esperar a que se desalojen todos los procesos. Si hay más de un dispositivo reiniciando en paralelo, el primer dispositivo llamará a kfd_suspend_all_processes() para desalojar todos los procesos en todos los dispositivos, esta llamada tarda un tiempo en finalizar. El otro dispositivo comenzará a restablecerse y recuperarse sin esperar. Si el proceso no ha sido desalojado antes de realizar la recuperación, se restaurará y luego provocará un error de página. • https://git.kernel.org/stable/c/b6f6626528fe724b512c34f3fb5946c36a135f58 https://git.kernel.org/stable/c/ed28ef3840bbf93a64376ea7814ce39f86352e14 https://git.kernel.org/stable/c/d06af584be5a769d124b7302b32a033e9559761d •

In the Linux kernel, the following vulnerability has been resolved: Reapply "drm/qxl: simplify qxl_fence_wait" This reverts commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea. Stephen Rostedt reports: "I went to run my tests on my VMs and the tests hung on boot up. Unfortunately, the most I ever got out was: [ 93.607888] Testing event system initcall: OK [ 93.667730] Running tests on all trace events: [ 93.669757] Testing all events: OK [ 95.631064] ------------[ cut here ]------------ Timed out after 60 seconds" and further debugging points to a possible circular locking dependency between the console_owner locking and the worker pool locking. Reverting the commit allows Steve's VM to boot to completion again. [ This may obviously result in the "[TTM] Buffer eviction failed" messages again, which was the reason for that original revert. But at this point this seems preferable to a non-booting system... ] En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Vuelva a aplicar "drm/qxl: simplificar qxl_fence_wait" Esto revierte el commit 07ed11afb68d94eadd4ffc082b97c2331307c5ea.
