CVE-2024-0582 – Kernel: io_uring: page use-after-free vulnerability via buffer ring mmap
https://notcve.org/view.php?id=CVE-2024-0582
A memory leak flaw was found in the Linux kernel’s io_uring functionality in how a user registers a buffer ring with IORING_REGISTER_PBUF_RING, mmap() it, and then frees it. This flaw allows a local user to crash or potentially escalate their privileges on the system. Se encontró un fallo de pérdida de memoria en la funcionalidad io_uring del kernel de Linux en cómo un usuario registra un anillo de búfer con IORING_REGISTER_PBUF_RING, mmap() y luego lo libera. este fallo permite que un usuario local falle o potencialmente aumente sus privilegios en el sistema. • https://github.com/ysanatomic/io_uring_LPE-CVE-2024-0582 https://github.com/Forsaken0129/CVE-2024-0582 http://www.openwall.com/lists/oss-security/2024/04/24/3 https://access.redhat.com/security/cve/CVE-2024-0582 https://bugs.chromium.org/p/project-zero/issues/detail? • CWE-416: Use After Free •

CVE-2023-44487 – HTTP/2: Multiple HTTP/2 enabled web servers are vulnerable to a DDoS attack (Rapid Reset Attack)
https://notcve.org/view.php?id=CVE-2023-44487
The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023. El protocolo HTTP/2 permite una denegación de servicio (consumo de recursos del servidor) porque la cancelación de solicitudes puede restablecer muchas transmisiones rápidamente, como se explotó en la naturaleza entre agosto y octubre de 2023. A flaw was found in handling multiplexed streams in the HTTP/2 protocol. A client can repeatedly make a request for a new multiplex stream and immediately send an RST_STREAM frame to cancel it. This creates extra work for the server setting up and tearing down the streams while not hitting any server-side limit for the maximum number of active streams per connection, resulting in a denial of service due to server resource consumption. • https://github.com/imabee101/CVE-2023-44487 https://github.com/studiogangster/CVE-2023-44487 https://github.com/bcdannyboy/CVE-2023-44487 https://github.com/sigridou/CVE-2023-44487- https://github.com/ByteHackr/CVE-2023-44487 https://github.com/ReToCode/golang-CVE-2023-44487 http://www.openwall.com/lists/oss-security/2023/10/13/4 http://www.openwall.com/lists/oss-security/2023/10/13/9 http://www.openwall.com/lists/oss-security/2023/10/18/4 http://www. • CWE-400: Uncontrolled Resource Consumption •

CVE-2023-4211 – Arm Mali GPU Kernel Driver Use-After-Free Vulnerability
https://notcve.org/view.php?id=CVE-2023-4211
A local non-privileged user can make improper GPU memory processing operations to gain access to already freed memory. Un usuario local sin privilegios puede realizar operaciones inadecuadas de procesamiento de la memoria de la GPU para obtener acceso a la memoria ya liberada. Arm Mali GPU Kernel Driver contains a use-after-free vulnerability that allows a local, non-privileged user to make improper GPU memory processing operations to gain access to already freed memory. • https://developer.arm.com/Arm%20Security%20Center/Mali%20GPU%20Driver%20Vulnerabilities • CWE-416: Use After Free •

CVE-2023-26072 – Shannon Baseband NrmmMsgCodec Emergency Number List Heap Buffer Overflow
https://notcve.org/view.php?id=CVE-2023-26072
An issue was discovered in Samsung Mobile Chipset and Baseband Modem Chipset for Exynos 850, Exynos 980, Exynos 1080, Exynos 1280, Exynos 2200, Exynos Modem 5123, Exynos Modem 5300, and Exynos Auto T5123. A heap-based buffer overflow in the 5G MM message codec can occur due to insufficient parameter validation when decoding the Emergency number list. There is a heap buffer overflow in Shannon baseband, inside the 5G MM protocol implementation (NrmmMsgCodec as it is called in Shannon according to debug strings), specifically when handling the "Emergency number list" message (IEI = 0x34). • http://packetstormsecurity.com/files/171378/Shannon-Baseband-NrmmMsgCodec-Emergency-Number-List-Heap-Buffer-Overflow.html https://bugs.chromium.org/p/project-zero/issues/detail?id=2395 https://googleprojectzero.blogspot.com/2023/03/multiple-internet-to-baseband-remote-rce.html https://semiconductor.samsung.com/processor/mobile-processor https://semiconductor.samsung.com/processor/modem https://semiconductor.samsung.com/support/quality-support/product-security-updates • CWE-787: Out-of-bounds Write •
