CVE-2019-15223 – kernel: Null pointer dereference in the sound/usb/line6/driver.c
https://notcve.org/view.php?id=CVE-2019-15223
An issue was discovered in the Linux kernel before 5.1.8. There is a NULL pointer dereference caused by a malicious USB device in the sound/usb/line6/driver.c driver. Se descubrió un problema en el kernel de Linux versiones anteriores a 5.1.8. Se presenta una desreferencia del puntero NULL causada por un dispositivo USB malicioso en el controlador sound/usb/line6/driver.c.

CVE-2018-16871 – kernel: nfs: NULL pointer dereference due to an anomalized NFS message sequence
https://notcve.org/view.php?id=CVE-2018-16871
A flaw was found in the Linux kernel's NFS implementation, all versions 3.x and all versions 4.x up to 4.20. An attacker, who is able to mount an exported NFS filesystem, is able to trigger a null pointer dereference by using an invalid NFS sequence. This can panic the machine and deny access to the NFS server. Any outstanding disk writes to the NFS server will be lost. Se detectó un fallo en la implementación de NFS del kernel de Linux, todas las versiones 3.x y todas las versiones 4.x hasta 4.20. • https://access.redhat.com/errata/RHSA-2019:2696 https://access.redhat.com/errata/RHSA-2019:2730 https://access.redhat.com/errata/RHSA-2020:0740 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-16871 https://security.netapp.com/advisory/ntap-20211004-0002 https://support.f5.com/csp/article/K18657134 https://support.f5.com/csp/article/K18657134?utm_source=f5support&%3Butm_medium=RSS https://access.redhat.com/security/cve/CVE-2018-16871 https://bugzilla.redhat.com/show_b • CWE-476: NULL Pointer Dereference •
CVE-2019-13272 – Linux Kernel Improper Privilege Management Vulnerability
https://notcve.org/view.php?id=CVE-2019-13272
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments. En el kernel de Linux anterior a versión 5.1.17, ptrace_link en el archivo kernel/ptrace.c maneja inapropiadamente la grabación de las credenciales de un proceso que desea crear una relación de ptrace, que permite a los usuarios locales obtener acceso de root aprovechando determinados escenarios con un relación de proceso padre-hijo, donde un padre elimina los privilegios y llama a execve (permitiendo potencialmente el control por parte de un atacante). • https://www.exploit-db.com/exploits/47133 https://www.exploit-db.com/exploits/47163 https://www.exploit-db.com/exploits/50541 https://www.exploit-db.com/exploits/47543 https://github.com/jas502n/CVE-2019-13272 https://github.com/Cyc1eC/CVE-2019-13272 https://github.com/oneoy/CVE-2019-13272 https://github.com/polosec/CVE-2019-13272 https://github.com/MDS1GNAL/ptrace_scope-CVE-2019-13272-privilege-escalation https://github.com/datntsec/CVE-2019-13272 https://github • CWE-271: Privilege Dropping / Lowering Errors •
