CVSS: 7.5EPSS: 0%CPEs: 30EXPL: 0CVE-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 •

https://notcve.org/view.php?id=CVE-2009-3547
Multiple race conditions in fs/pipe.c in the Linux kernel before 2.6.32-rc6 allow local users to cause a denial of service (NULL pointer dereference and system crash) or gain privileges by attempting to open an anonymous pipe via a /proc/*/fd/ pathname. Múltiples condiciones de carrera en fs/pipe.c en el kernel de Linux anteriores a v2.6.32-rc6 permite a usuarios locales producir una denegación de servicio )desreferencia a puntero NULL y caída del sistema) o conseguir privilegios mediante la apertura de un canal anónimo en la ruta /proc/*/fd/. • https://www.exploit-db.com/exploits/9844 https://www.exploit-db.com/exploits/33321 https://www.exploit-db.com/exploits/10018 https://www.exploit-db.com/exploits/33322 https://www.exploit-db.com/exploits/40812 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=ad3960243e55320d74195fb85c975e0a8cc4466c http://lists.opensuse.org/opensuse-security-announce/2009-11/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2009-11/msg00007.html http:/ • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') CWE-476: NULL Pointer Dereference CWE-672: Operation on a Resource after Expiration or Release •
CVSS: 7.8EPSS: 0%CPEs: 16EXPL: 0CVE-2009-3620 – kernel: r128 IOCTL NULL pointer dereferences when CCE state is uninitialised
https://notcve.org/view.php?id=CVE-2009-3620
The ATI Rage 128 (aka r128) driver in the Linux kernel before 2.6.31-git11 does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls. El controlador ATI Rage 128 (también conocido como r128), en el Kernel de Linux anterior a v2.6.31-git11 no verifica de forma adecuada el estado de inicialización del "Concurrent Command Engine (CCE)", lo que permite a usuarios locales provocar una denegación de servicio (desreferenciación de puntero nulo y caída del sistema) o posiblemente obtener privilegios a través de llamadas ioctl sin especificar. • http://article.gmane.org/gmane.linux.kernel/892259 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git%3Ba=commit%3Bh=7dc482dfeeeefcfd000d4271c4626937406756d7 http://lists.opensuse.org/opensuse-security-announce/2009-12/msg00002.html http://lists.opensuse.org/opensuse-security-announce/2009-12/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2010-02/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2010-02/msg00007.html http://lists.vmware.com/pipermail/sec • CWE-476: NULL Pointer Dereference CWE-908: Use of Uninitialized Resource •
