https://notcve.org/view.php?id=CVE-2023-52878
In the Linux kernel, the following vulnerability has been resolved: can: dev: can_put_echo_skb(): don't crash kernel if can_priv::echo_skb is accessed out of bounds If the "struct can_priv::echoo_skb" is accessed out of bounds, this would cause a kernel crash. Instead, issue a meaningful warning message and return with an error. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: can: dev: can_put_echo_skb(): no bloquee el kernel si se accede a can_priv::echo_skb fuera de los límites. Si se accede a "struct can_priv::echoo_skb" fuera de los límites, esto provocaría un fallo del kernel. En su lugar, emita un mensaje de advertencia significativo y regrese con un error. • https://git.kernel.org/stable/c/a6e4bc5304033e434fabccabb230b8e9ff55d76f https://git.kernel.org/stable/c/826120c9ba68f2d0dbae58e99013929c883d1444 https://git.kernel.org/stable/c/0d30931f1fa0fb893fb7d5dc32b6b7edfb775be4 https://git.kernel.org/stable/c/53c468008a7c9ca3f5fc985951f35ec2acae85bc https://git.kernel.org/stable/c/8ab67da060157362b2e0926692c659808784708f https://git.kernel.org/stable/c/6411959c10fe917288cbb1038886999148560057 https://access.redhat.com/security/cve/CVE-2023-52878 https://bugzilla.redhat.com/show_bug.cgi?id=2282680 • CWE-125: Out-of-bounds Read •

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.

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 •
