https://notcve.org/view.php?id=CVE-2020-9391
An issue was discovered in the Linux kernel 5.4 and 5.5 through 5.5.6 on the AArch64 architecture. It ignores the top byte in the address passed to the brk system call, potentially moving the memory break downwards when the application expects it to move upwards, aka CID-dcde237319e6. This has been observed to cause heap corruption with the GNU C Library malloc implementation. Se detectó un problema en el kernel de Linux versión 5.4 y versiones 5.5 hasta 5.5.6 sobre la arquitectura AArch64. Ignora el byte superior en la dirección pasada a la llamada de sistema brk, posiblemente moviendo la memoria hacia abajo cuando la aplicación espera que se mueva hacia arriba, también se conoce como CID-dcde237319e6. • http://www.openwall.com/lists/oss-security/2020/02/25/6 https://bugzilla.redhat.com/show_bug.cgi?id=1797052 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=dcde237319e626d1ec3c9d8b7613032f0fd4663a https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/O4LH35HOPBJIKYHYFXMBBM75DN75PZHZ https://security.netapp.com/advisory/ntap-20200313-0003 • CWE-787: Out-of-bounds Write •
CVSS: 7.1EPSS: 0%CPEs: 18EXPL: 0CVE-2020-9383 – kernel: out-of-bounds read in set_fdc in drivers/block/floppy.c
https://notcve.org/view.php?id=CVE-2020-9383
An issue was discovered in the Linux kernel 3.16 through 5.5.6. set_fdc in drivers/block/floppy.c leads to a wait_til_ready out-of-bounds read because the FDC index is not checked for errors before assigning it, aka CID-2e90ca68b0d2. Se detectó un problema en el kernel de Linux versión 3.16 hasta la versión 5.5.6. La función set_fdc en el archivo drivers/block/floppy.c, conlleva a una lectura fuera de límites de wait_til_ready porque el índice FDC no es comprobado para errores antes de asignarlos, también se conoce como CID-2e90ca68b0d2 An out-of-bounds (OOB) memory access flaw was found in the floppy driver module in the Linux kernel. A bounds check failure allows a local attacker to gain access to out-of-bounds memory leading to a system crash or a leak of internal kernel information. The highest threat from this vulnerability is to system availability. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00039.html https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=2f9ac30a54dc0181ddac3705cdcf4775d863c530 https://github.com/torvalds/linux/commit/2e90ca68b0d2f5548804f22f0dd61145516171e3 https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https://security.netapp.com/advisory/ntap& • CWE-125: Out-of-bounds Read •

A use-after-free in binder.c allows an elevation of privilege from an application to the Linux Kernel. No user interaction is required to exploit this vulnerability, however exploitation does require either the installation of a malicious local application or a separate vulnerability in a network facing application.Product: AndroidAndroid ID: A-141720095 Un uso de la memoria previamente liberada en el archivo binder.c, permite una elevación de privilegios desde una aplicación en el kernel de Linux. No es requerida una interacción del usuario para explotar esta vulnerabilidad, sin embargo, la explotación necesita de la instalación de una aplicación local maliciosa o una vulnerabilidad separada en una aplicación de red. Producto: Android; ID de Android: A-141720095 Android suffers from a use-after-free vulnerability in the binder driver at /drivers/android/binder.c. Android Kernel contains a use-after-free vulnerability in binder.c that allows for privilege escalation from an application to the Linux Kernel. • https://www.exploit-db.com/exploits/48129 https://www.exploit-db.com/exploits/47463 https://github.com/timwr/CVE-2019-2215 https://github.com/LIznzn/CVE-2019-2215 https://github.com/ATorNinja/CVE-2019-2215 https://github.com/stevejubx/CVE-2019-2215 https://github.com/c3r34lk1ll3r/CVE-2019-2215 https://github.com/qre0ct/android-kernel-exploitation-ashfaq-CVE-2019-2215 https://github.com/mufidmb38/CVE-2019-2215 https://github.com/Byte-Master-101/CVE-2019-2215 https: • CWE-416: Use After Free •
