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 •

CVSS: 7.9EPSS: 0%CPEs: 36EXPL: 1CVE-2021-3752 – kernel: possible use-after-free in bluetooth module
https://notcve.org/view.php?id=CVE-2021-3752
A use-after-free flaw was found in the Linux kernel’s Bluetooth subsystem in the way user calls connect to the socket and disconnect simultaneously due to a race condition. This flaw allows a user to crash the system or escalate their privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. Se ha encontrado un fallo de uso de memoria previamente liberada en el subsistema Bluetooth del kernel de Linux en la forma en que las llamadas de usuario son conectadas al socket y son desconectadas simultáneamente debido a una condición de carrera. Este fallo permite a un usuario bloquear el sistema o escalar sus privilegios. • https://bugzilla.redhat.com/show_bug.cgi?id=1999544 https://lists.debian.org/debian-lts-announce/2022/03/msg00011.html https://lists.debian.org/debian-lts-announce/2022/03/msg00012.html https://lore.kernel.org/lkml/20211115165435.133245729%40linuxfoundation.org https://security.netapp.com/advisory/ntap-20220318-0009 https://www.debian.org/security/2022/dsa-5096 https://www.openwall.com/lists/oss-security/2021/09/15/4 https://www.oracle.com/security-alerts/cpujul2022.html https:/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-416: Use After Free •
