In the Linux kernel, the following vulnerability has been resolved: thermal: core: prevent potential string overflow The dev->id value comes from ida_alloc() so it's a number between zero and INT_MAX. If it's too high then these sprintf()s will overflow. En el kernel de Linux, se resolvió la siguiente vulnerabilidad: térmica: núcleo: evita un posible desbordamiento de cadenas. El valor dev->id proviene de ida_alloc(), por lo que es un número entre cero e INT_MAX. Si es demasiado alto, estos sprintf()s se desbordarán. • https://git.kernel.org/stable/c/203d3d4aa482339b4816f131f713e1b8ee37f6dd https://git.kernel.org/stable/c/b55f0a9f865be75ca1019aad331f3225f7b50ce8 https://git.kernel.org/stable/c/6ad1bf47fbe5750c4d5d8e41337665e193e2c521 https://git.kernel.org/stable/c/3091ab943dfc7b2578599b0fe203350286fab5bb https://git.kernel.org/stable/c/3f795fb35c2d8a637efe76b4518216c9319b998c https://git.kernel.org/stable/c/3a8f4e58e1ee707b4f46a1000b40b86ea3dd509c https://git.kernel.org/stable/c/77ff34a56b695e228e6daf30ee30be747973d6e8 https://git.kernel.org/stable/c/0f6b3be28c4d62ef6498133959c722666 •

CVSS: 4.4EPSS: 0%CPEs: 8EXPL: 0CVE-2023-52864 – platform/x86: wmi: Fix opening of char device
https://notcve.org/view.php?id=CVE-2023-52864
In the Linux kernel, the following vulnerability has been resolved: platform/x86: wmi: Fix opening of char device Since commit fa1f68db6ca7 ("drivers: misc: pass miscdevice pointer via file private data"), the miscdevice stores a pointer to itself inside filp->private_data, which means that private_data will not be NULL when wmi_char_open() is called. This might cause memory corruption should wmi_char_open() be unable to find its driver, something which can happen when the associated WMI device is deleted in wmi_free_devices(). Fix the problem by using the miscdevice pointer to retrieve the WMI device data associated with a char device using container_of(). This also avoids wmi_char_open() picking a wrong WMI device bound to a driver with the same name as the original driver. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: plataforma/x86: wmi: corrige la apertura del dispositivo char. Desde la confirmación fa1f68db6ca7 ("drivers: misc: pasar el puntero del dispositivo misc a través de datos privados del archivo"), el dispositivo misc almacena un puntero a sí mismo en su interior. filp->private_data, lo que significa que private_data no será NULL cuando se llame a wmi_char_open(). • https://git.kernel.org/stable/c/44b6b7661132b1b0e5fd3147ded66f1e4a817ca9 https://git.kernel.org/stable/c/cf098e937dd125c0317a0d6f261ac2a950a233d6 https://git.kernel.org/stable/c/9fb0eed09e1470cd4021ff52b2b9dfcbcee4c203 https://git.kernel.org/stable/c/d426a2955e45a95b2282764105fcfb110a540453 https://git.kernel.org/stable/c/e0bf076b734a2fab92d8fddc2b8b03462eee7097 https://git.kernel.org/stable/c/44a96796d25809502c75771d40ee693c2e44724e https://git.kernel.org/stable/c/36d85fa7ae0d6be651c1a745191fa7ef055db43e https://git.kernel.org/stable/c/fb7b06b59c6887659c6ed0ecd3110835e • CWE-402: Transmission of Private Resources into a New Sphere ('Resource Leak') •
CVSS: -EPSS: 0%CPEs: 9EXPL: 0CVE-2023-52855 – usb: dwc2: fix possible NULL pointer dereference caused by driver concurrency
https://notcve.org/view.php?id=CVE-2023-52855
In the Linux kernel, the following vulnerability has been resolved: usb: dwc2: fix possible NULL pointer dereference caused by driver concurrency In _dwc2_hcd_urb_enqueue(), "urb->hcpriv = NULL" is executed without holding the lock "hsotg->lock". In _dwc2_hcd_urb_dequeue(): spin_lock_irqsave(&hsotg->lock, flags); ... if (!urb->hcpriv) { dev_dbg(hsotg->dev, "## urb->hcpriv is NULL ##\n"); goto out; } rc = dwc2_hcd_urb_dequeue(hsotg, urb->hcpriv); // Use urb->hcpriv ... out: spin_unlock_irqrestore(&hsotg->lock, flags); When _dwc2_hcd_urb_enqueue() and _dwc2_hcd_urb_dequeue() are concurrently executed, the NULL check of "urb->hcpriv" can be executed before "urb->hcpriv = NULL". After urb->hcpriv is NULL, it can be used in the function call to dwc2_hcd_urb_dequeue(), which can cause a NULL pointer dereference. This possible bug is found by an experimental static analysis tool developed by myself. This tool analyzes the locking APIs to extract function pairs that can be concurrently executed, and then analyzes the instructions in the paired functions to identify possible concurrency bugs including data races and atomicity violations. • https://git.kernel.org/stable/c/33ad261aa62be02f0cedeb4d5735cc726de84a3f https://git.kernel.org/stable/c/14c9ec34e8118fbffd7f5431814d767726323e72 https://git.kernel.org/stable/c/fed492aa6493a91a77ebd51da6fb939c98d94a0d https://git.kernel.org/stable/c/64c47749fc7507ed732e155c958253968c1d275e https://git.kernel.org/stable/c/bdb3dd4096302d6b87441fdc528439f171b04be6 https://git.kernel.org/stable/c/fcaafb574fc88a52dce817f039f7ff2f9da38001 https://git.kernel.org/stable/c/6b21a22728852d020a6658d39cd7bb7e14b07790 https://git.kernel.org/stable/c/3e851a77a13ce944d703721793f49ee82 •
