https://notcve.org/view.php?id=CVE-2022-25265
In the Linux kernel through 5.16.10, certain binary files may have the exec-all attribute if they were built in approximately 2003 (e.g., with GCC 3.2.2 and Linux kernel 2.4.20). This can cause execution of bytes located in supposedly non-executable regions of a file. En el kernel de Linux versiones hasta 5.16.10, determinados archivos binarios pueden tener el atributo exec-all si fueron construidos aproximadamente en 2003 (por ejemplo, con GCC versión 3.2.2 y el kernel de Linux versión 2.4.20). Esto puede causar una ejecución de bytes ubicados en regiones supuestamente no ejecutables de un archivo A vulnerability was found in the Linux kernel when certain binary files have the exec-all attribute with gcc.

An issue was discovered in drivers/usb/gadget/composite.c in the Linux kernel before 5.16.10. The USB Gadget subsystem lacks certain validation of interface OS descriptor requests (ones with a large array index and ones associated with NULL function pointer retrieval). Memory corruption might occur. Se ha descubierto un problema en drivers/usb/gadget/composite.c en el kernel de Linux anterior a la versión 5.16.10. El subsistema USB Gadget carece de cierta validación de las solicitudes de descriptor del SO de la interfaz (las que tienen un índice de matriz grande y las asociadas a la recuperación de punteros de función NULL). • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.16.10 https://github.com/szymonh/d-os-descriptor https://github.com/torvalds/linux/commit/75e5b4849b81e19e9efe1654b30d7f3151c33c2c https://lists.debian.org/debian-lts-announce/2022/03/msg00011.html https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/TCW2KZYJ2H6BKZE3CVLHRIXYDGNYYC5P https://security.netapp.com/advisory/ntap-20221028-0007 https:/ • CWE-476: NULL Pointer Dereference •
