An issue was discovered in the stv06xx subsystem in the Linux kernel before 5.6.1. drivers/media/usb/gspca/stv06xx/stv06xx.c and drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c mishandle invalid descriptors, as demonstrated by a NULL pointer dereference, aka CID-485b06aadb93. Se detectó un problema en el subsistema stv06xx en el kernel de Linux versiones anteriores a 5.6.1. Los archivos drivers/media/usb/gspca/stv06xx/stv06xx.c y drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c manejan inapropiadamente los descriptores no válidos, como es demostrado por una desreferencia del puntero NULL, también se conoce como CID-485b06aadb93. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.6.1 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=485b06aadb933190f4bc44e006076bc27a23f205 https://github.com/torvalds/linux/commit/485b06aadb933190f4bc44e006076bc27a23f205 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-a • CWE-476: NULL Pointer Dereference •
CVSS: 4.9EPSS: 0%CPEs: 3EXPL: 0CVE-2020-11608 – kernel: NULL pointer dereferences in ov511_mode_init_regs and ov518_mode_init_regs in drivers/media/usb/gspca/ov519.c
https://notcve.org/view.php?id=CVE-2020-11608
An issue was discovered in the Linux kernel before 5.6.1. drivers/media/usb/gspca/ov519.c allows NULL pointer dereferences in ov511_mode_init_regs and ov518_mode_init_regs when there are zero endpoints, aka CID-998912346c0d. Se detectó un problema en el kernel de Linux versiones anteriores a 5.6.1. El archivo drivers/media/usb/gspca/ov519.c, permite desreferencias del puntero NULL en las funciones ov511_mode_init_regs y ov518_mode_init_regs cuando hay cero endpoints, también se conoce como CID-998912346c0d. A flaw was found in the way the ov519 driver in the Linux kernel handled certain types of USB descriptors. This flaw allows an attacker with the ability to induce the error conditions to crash the system. • http://lists.opensuse.org/opensuse-security-announce/2020-06/msg00022.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.6.1 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=998912346c0da53a6dbb71fab3a138586b596b30 https://github.com/torvalds/linux/commit/998912346c0da53a6dbb71fab3a138586b596b30 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-a • CWE-476: NULL Pointer Dereference •
CVSS: 6.0EPSS: 0%CPEs: 5EXPL: 0CVE-2020-11565 – kernel: out-of-bounds write in mpol_parse_str function in mm/mempolicy.c
https://notcve.org/view.php?id=CVE-2020-11565
An issue was discovered in the Linux kernel through 5.6.2. mpol_parse_str in mm/mempolicy.c has a stack-based out-of-bounds write because an empty nodelist is mishandled during mount option parsing, aka CID-aa9f7d5172fa. NOTE: Someone in the security community disagrees that this is a vulnerability because the issue “is a bug in parsing mount options which can only be specified by a privileged user, so triggering the bug does not grant any powers not already held.” ** EN DISPUTA ** Se detectó un problema en el kernel de Linux versiones hasta 5.6.2. La función mpol_parse_str en el archivo mm/mempolicy.c presenta una escritura fuera de límites en la región stack de la memoria porque una lista de nodos vacía es manejada inapropiadamente durante el análisis de la opción de montaje, también se conoce como CID-aa9f7d5172fa. NOTA: Alguien en la comunidad de seguridad no está de acuerdo en que se trata de una vulnerabilidad porque el problema "es un error en el análisis de las opciones de montaje que sólo puede ser especificado por un usuario privilegiado, por lo que la activación del error no otorga ningún poder que no se tenga ya". An out-of-bounds write flaw was found in the Linux kernel. • https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=aa9f7d5172fac9bf1f09e678c35e287a40a7b7dd https://github.com/torvalds/linux/commit/aa9f7d5172fac9bf1f09e678c35e287a40a7b7dd 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://usn.ubuntu.com/4363-1 https://usn.ubuntu.com/4364-1 https://usn.ubuntu.com/4367-1 https:&# • CWE-787: Out-of-bounds Write •

https://notcve.org/view.php?id=CVE-2020-11501
GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 (2018-07-16) because of an error in a 2017-10-06 commit. The DTLS client always uses 32 '\0' bytes instead of a random value, and thus contributes no randomness to a DTLS negotiation. This breaks the security guarantees of the DTLS protocol. GnuTLS versiones 3.6.x anteriores a 3.6.13, usa una criptografía incorrecta para DTLS. • http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00015.html https://gitlab.com/gnutls/gnutls/-/commit/5b595e8e52653f6c5726a4cdd8fddeb6e83804d2 https://gitlab.com/gnutls/gnutls/-/issues/960 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/ILMOWPKMTZAIMK5F32TUMO34XCABUCFJ https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/WDYY3R4F5CUTFAMXH2C5NKYFVDEJLTT7 https://security.gentoo.org/glsa/202004-06 https://security.netapp.com/advis • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-330: Use of Insufficiently Random Values •

An issue was discovered in slc_bump in drivers/net/can/slcan.c in the Linux kernel 3.16 through 5.6.2. It allows attackers to read uninitialized can_frame data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL, aka CID-b9258a2cece4. Se detectó un problema en la función slc_bump en el archivo drivers/net/can/slcan.c en el kernel de Linux versión 3.16 hasta la versión 5.6.2. Permite a atacantes leer datos de can_frame no inicializados, conteniendo potencialmente información confidencial de la memoria de la pila del kernel, si la configuración carece de CONFIG_INIT_STACK_ALL, también se conoce como CID-b9258a2cece4 • http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00035.html http://packetstormsecurity.com/files/159565/Kernel-Live-Patch-Security-Notice-LSN-0072-1.html https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=08fadc32ce6239dc75fd5e869590e29bc62bbc28 https://github.com/torvalds/linux/commit/b9258a2cece4ec1f020715fe3554bc2e360f6264 https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00012.html https://lists.debi • CWE-908: Use of Uninitialized Resource CWE-909: Missing Initialization of Resource •
