In the Linux kernel before 5.1, there is a memory leak in __feat_register_sp() in net/dccp/feat.c, which may cause denial of service, aka CID-1d3ff0950e2b. En el kernel de Linux versiones anteriores a la versión 5.1, hay una pérdida de memoria en la función __feat_register_sp() en el archivo net/dccp/feat.c, lo que puede causar una denegación de servicio, también se conoce como CID-1d3ff0950e2b. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html http://packetstormsecurity.com/files/156455/Kernel-Live-Patch-Security-Notice-LSN-0063-1.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.1 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=1d3ff0950e2b40dc861b1739029649d03f591820 https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://usn.ubuntu.com/4285-1 https://usn.ubuntu.com/4286-1 https://usn& • CWE-401: Missing Release of Memory after Effective Lifetime •
CVE-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 •
CVE-2011-1474
https://notcve.org/view.php?id=CVE-2011-1474
A locally locally exploitable DOS vulnerability was found in pax-linux versions 2.6.32.33-test79.patch, 2.6.38-test3.patch, and 2.6.37.4-test14.patch. A bad bounds check in arch_get_unmapped_area_topdown triggered by programs doing an mmap after a MAP_GROWSDOWN mmap will create an infinite loop condition without releasing the VM semaphore eventually leading to a system crash. Se encontró una vulnerabilidad de DOS explotable localmente en pax-linux versiones 2.6.32.33-test79.patch, 2.6.38-test3.patch y 2.6.37.4-test14.patch. Una comprobación de límites incorrecta en la función arch_get_unmapped_area_topdown activada por programas que hacen un mmap después de un mmap MAP_GROWSDOWN creará una condición de bucle infinito sin liberar el semáforo VM conllevando eventualmente a un bloqueo del sistema. • http://seclists.org/oss-sec/2011/q1/579 https://security-tracker.debian.org/tracker/CVE-2011-1474 • CWE-400: Uncontrolled Resource Consumption CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop') •
CVE-2019-19965
https://notcve.org/view.php?id=CVE-2019-19965
In the Linux kernel through 5.4.6, there is a NULL pointer dereference in drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related to a PHY down race condition, aka CID-f70267f379b5. En el kernel de Linux versiones hasta 5.4.6, se presenta una desreferencia del puntero NULL en el archivo drivers/scsi/libsas/sas_discover.c debido a un manejo inapropiado de la desconexión del puerto durante la detección, relacionado con una condición de carrera baja PHY, también se conoce como CID-f70267f379b5. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=f70267f379b5e5e11bdc5d72a56bf17e5feed01f https://lists.debian.org/debian-lts-announce/2020/01/msg00013.html https://lists.debian.org/debian-lts-announce/2020/03/msg00001.html https://security.netapp.com/advisory/ntap-20200204-0002 https://usn.ubuntu.com/4284-1 https://usn.ubuntu.com/4285-1 https://usn.ubuntu.com/4286-1 https:// • CWE-476: NULL Pointer Dereference •

In the Linux kernel before 5.1.6, there is a use-after-free in cpia2_exit() in drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service, aka CID-dea37a972655. En el kernel de Linux versiones anteriores a 5.1.6, se presenta un uso de la memoria previamente liberada de la función cpia2_exit() en el archivo drivers/media/usb/cpia2/cpia2_v4l.c que causará una denegación de servicio, también se conoce como CID-dea37a972655. • http://lists.opensuse.org/opensuse-security-announce/2020-03/msg00021.html https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.1.6 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=dea37a97265588da604c6ba80160a287b72c7bfd https://lists.debian.org/debian-lts-announce/2020/01/msg00013.html https://security.netapp.com/advisory/ntap-20200204-0002 • CWE-416: Use After Free •
