The irda_setsockopt function in net/irda/af_irda.c and later in drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17 allows local users to cause a denial of service (ias_object use-after-free and system crash) or possibly have unspecified other impact via an AF_IRDA socket. La función irda_setsockopt en net/irda/af_irda.c y siguientes en drivers/staging/irda/net/af_irda.c en el kernel de Linux en versiones anteriores a la 4.17 permite que usuarios locales provoquen una denegación de servicio (uso de memoria previamente liberada en ias_object y cierre inesperado del sistema) o cualquier otro tipo de impacto sin especificar mediante un socket AF_IRDA. • http://www.securityfocus.com/bid/105304 https://lists.debian.org/debian-lts-announce/2018/10/msg00003.html https://usn.ubuntu.com/3775-1 https://usn.ubuntu.com/3775-2 https://usn.ubuntu.com/3776-1 https://usn.ubuntu.com/3776-2 https://usn.ubuntu.com/3777-1 https://usn.ubuntu.com/3777-2 https://usn.ubuntu.com/3777-3 https://www.debian.org/security/2018/dsa-4308 https://www.spinics.net/lists/stable/msg255031.html https://www.spinics.net/lists • CWE-416: Use After Free •

Memory leak in the irda_bind function in net/irda/af_irda.c and later in drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17 allows local users to cause a denial of service (memory consumption) by repeatedly binding an AF_IRDA socket.

An issue was discovered in yurex_read in drivers/usb/misc/yurex.c in the Linux kernel before 4.17.7. Local attackers could use user access read/writes with incorrect bounds checking in the yurex USB driver to crash the kernel or potentially escalate privileges. Se descubrió un problema en yurex_read en drivers/usb/misc/yurex.c en el kernel de Linux hasta la versión 4.17.7. Los atacantes locales pueden emplear lecturas/escrituras de acceso de usuario con una comprobación incorrecta de límites en el controlador USB yurex para provocar el cierre inesperado del kernel o escalar privilegios. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f1e255d60ae66a9f672ff9a207ee6cd8e33d2679 https://bugzilla.suse.com/show_bug.cgi?id=1106095 https://bugzilla.suse.com/show_bug.cgi?id=1115593 https://cdn.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.17.7 https://github.com/torvalds/linux/commit/f1e255d60ae66a9f672ff9a207ee6cd8e33d2679 https://lists.debian.org/debian-lts-announce/2018/10/msg00003.html https://usn.ubuntu.com/3776-1 https://usn.ubuntu.com/3776-2 https • CWE-787: Out-of-bounds Write •
CVSS: 7.8EPSS: 0%CPEs: 4EXPL: 0CVE-2018-14619 – kernel: crash (possible privesc) in kernel crypto api.
https://notcve.org/view.php?id=CVE-2018-14619
A flaw was found in the crypto subsystem of the Linux kernel before version kernel-4.15-rc4. The "null skcipher" was being dropped when each af_alg_ctx was freed instead of when the aead_tfm was freed. This can cause the null skcipher to be freed while it is still in use leading to a local user being able to crash the system or possibly escalate privileges. Se ha encontrado un error en el subsistema crypto del kernel de Linux en versiones anteriores a kernel-4.15-rc4. Se dejó "null skcipher" cuando se liberó cada af_alg_ctx en lugar de cuando se liberó aead_tfm. • http://www.securityfocus.com/bid/105200 https://access.redhat.com/errata/RHSA-2018:2948 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2018-14619 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b32a7dc8aef1882fbf983eb354837488cc9d54dc https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2018-0013 https://access.redhat.com/security/cve/CVE-2018-14619 https://bugzilla.redhat.com/show_bug.cgi?id=1622004 • CWE-20: Improper Input Validation CWE-416: Use After Free •
