An issue was discovered in the Linux kernel before 5.0.19. The XFRM subsystem has a use-after-free, related to an xfrm_state_fini panic, aka CID-dbb2483b2a46. Se ha detectado un problema en el kernel de Linux versiones anteriores a 5.0.19. El subsistema XFRM presenta un uso de la memoria previamente liberada, relacionado con un pánico de la función xfrm_state_fini, también se conoce como CID-dbb2483b2a46 • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.0.19 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=dbb2483b2a46fbaf833cfb5deb5ed9cace9c7399 https://security.netapp.com/advisory/ntap-20210720-0003 https://sites.google.com/view/syzscope/warning-in-xfrm_state_fini-2 https://syzkaller.appspot.com/bug?id=f99edaeec58ad40380ed5813d89e205861be2896 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2020-15436
Use-after-free vulnerability in fs/block_dev.c in the Linux kernel before 5.8 allows local users to gain privileges or cause a denial of service by leveraging improper access to a certain error field. La vulnerabilidad de tipo use-after-free en el archivo fs/block_dev.c en el kernel de Linux versiones anteriores a 5.8, permite a usuarios locales obtener privilegios o causar una denegación de servicio al aprovechar el acceso inapropiado a un determinado campo de error A use-after-free flaw was observed in blkdev_get(), in fs/block_dev.c after a call to __blkdev_get() fails, and its refcount gets freed/released. This problem may cause a denial of service problem with a special user privilege, and may even lead to a confidentiality issue. • https://lkml.org/lkml/2020/6/7/379 https://security.netapp.com/advisory/ntap-20201218-0002 https://access.redhat.com/security/cve/CVE-2020-15436 https://bugzilla.redhat.com/show_bug.cgi?id=1901168 • CWE-416: Use After Free •
CVSS: 7.2EPSS: 0%CPEs: 23EXPL: 0CVE-2019-20636 – kernel: out-of-bounds write via crafted keycode table
https://notcve.org/view.php?id=CVE-2019-20636
In the Linux kernel before 5.4.12, drivers/input/input.c has out-of-bounds writes via a crafted keycode table, as demonstrated by input_set_keycode, aka CID-cb222aed03d7. En el kernel de Linux versiones anteriores a 5.4.12, el archivo drivers/input/input.c presenta escrituras fuera de límites por medio de una tabla de códigos clave diseñada, como es demostrado en la función input_set_keycode, también se conoce como CID-cb222aed03d7. An out-of-bounds write flaw was found in the Linux kernel. A crafted keycode table could be used by drivers/input/input.c to perform the out-of-bounds write. A local user with root access can insert garbage to this keycode table that can lead to out-of-bounds memory access. • https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.4.12 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=cb222aed03d798fc074be55e59d9a112338ee784 https://github.com/torvalds/linux/commit/cb222aed03d798fc074be55e59d9a112338ee784 https://lists.debian.org/debian-lts-announce/2020/06/msg00011.html https://lists.debian.org/debian-lts-announce/2020/06/msg00013.html https://security.netapp.com/advisory/ntap-20200430-0004 https://access.redhat.com/security/cve/CVE-2019-20 • CWE-787: Out-of-bounds Write •

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 •
