CVSS: 5.5EPSS: 0%CPEs: 63EXPL: 0CVE-2020-8832 – Ubuntu 18.04 Linux kernel i915 incomplete fix for CVE-2019-14615
https://notcve.org/view.php?id=CVE-2020-8832
The fix for the Linux kernel in Ubuntu 18.04 LTS for CVE-2019-14615 ("The Linux kernel did not properly clear data structures on context switches for certain Intel graphics processors.") was discovered to be incomplete, meaning that in versions of the kernel before 4.15.0-91.92, an attacker could use this vulnerability to expose sensitive information. Se detectó que la solución para el kernel de Linux en Ubuntu versión 18.04 LTS para CVE-2019-14615 ("El kernel de Linux no borró apropiadamente las estructuras de datos en los conmutadores de contexto para determinados procesadores gráficos de Intel") estaba incompleta, lo que significa que en las versiones de kernel anteriores a 4.15.0-91.92, un atacante podría usar esta vulnerabilidad para exponer información confidencial. • https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1862840 https://security.netapp.com/advisory/ntap-20200430-0004 https://usn.ubuntu.com/usn/usn-4302-1 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •

CVSS: 5.3EPSS: 0%CPEs: 19EXPL: 0CVE-2019-18282 – kernel: The flow_dissector feature allows device tracking
https://notcve.org/view.php?id=CVE-2019-18282
The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code. La función flow_dissector en el kernel de Linux 4.3 a 5.x anterior a la versión 5.3.10 tiene una vulnerabilidad de seguimiento del dispositivo, también conocida como CID-55667441c84f. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.3.10 https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=55667441c84fa5e0911a0aac44fb059c15ba6da2 https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://security.netapp.com/advisory/ntap-20200204-0002 https://www.computer.org/csdl/proceedings-article/sp/2020/349700b594/1j2LgrHDR2o https://access.redhat.com/security/cve/CVE-2019-18282 https://bugzilla.redhat.com/show_bug.cgi?id=1796360 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-330: Use of Insufficiently Random Values •

https://notcve.org/view.php?id=CVE-2019-20095
mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c in the Linux kernel before 5.1.6 has some error-handling cases that did not free allocated hostcmd memory, aka CID-003b686ace82. This will cause a memory leak and denial of service. La función mwifiex_tm_cmd en el archivo drivers/net/wireless/marvell/mwifiex/cfg80211.c en el kernel de Linux versiones anteriores a la versión 5.1.6 tiene algunos casos de manejo de errores que no liberaron la memoria hostcmd asignada, también se conoce como CID-003b686ace82. Esto causará una pérdida de memoria y una denegación de servicio.

CVSS: 5.5EPSS: 0%CPEs: 17EXPL: 0CVE-2019-20054 – kernel: Null pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c
https://notcve.org/view.php?id=CVE-2019-20054
In the Linux kernel before 5.0.6, there is a NULL pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c, related to put_links, aka CID-23da9588037e. En el kernel de Linux versiones anteriores a la versión 5.0.6, hay una desreferencia del puntero NULL en la función drop_sysctl_table() en el archivo fs/proc/proc_sysctl.c, relacionado con put_links, también se conoce como CID-23da9588037e. A flaw was found in the Linux kernel’s implementation of dropping sysctl entries. A local attacker who has access to load modules on the system can trigger a condition during module load failure and panic the system. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.11 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.6 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=23da9588037ecdd4901db76a5b79a42b529c4ec3 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=89189557b47b35683a27c80ee78aef18248eefb4 https://security.netapp.com/advisory/ntap-20200204-0002 https&# • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer CWE-476: NULL Pointer Dereference •
