The ims_pcu_get_cdc_union_desc function in drivers/input/misc/ims-pcu.c in the Linux kernel through 4.13.11 allows local users to cause a denial of service (ims_pcu_parse_cdc_data out-of-bounds read and system crash) or possibly have unspecified other impact via a crafted USB device. La función ims_pcu_get_cdc_union_desc en drivers/input/misc/ims-pcu.c en el kernel de Linux, en versiones anteriores a la 4.13.11, permite que los usuarios locales provoquen una denegación de servicio (lectura fuera de límites de ims_pcu_parse_cdc_data y cierre inesperado del sistema) o, posiblemente, causen otros impactos no especificados mediante un dispositivo USB manipulado. • http://www.securityfocus.com/bid/101768 https://github.com/torvalds/linux/commit/ea04efee7635c9120d015dcdeeeb6988130cb67a https://groups.google.com/d/msg/syzkaller/q6jjr1OhqO8/WcA99AVFBAAJ https://usn.ubuntu.com/3617-1 https://usn.ubuntu.com/3617-2 https://usn.ubuntu.com/3617-3 https://usn.ubuntu.com/3619-1 https://usn.ubuntu.com/3619-2 https://usn.ubuntu.com/3754-1 • CWE-125: Out-of-bounds Read •

CVSS: 6.1EPSS: 0%CPEs: 30EXPL: 0CVE-2017-15129 – kernel: net: double-free and memory corruption in get_net_ns_by_id()
https://notcve.org/view.php?id=CVE-2017-15129
A use-after-free vulnerability was found in network namespaces code affecting the Linux kernel before 4.14.11. The function get_net_ns_by_id() in net/core/net_namespace.c does not check for the net::count value after it has found a peer network in netns_ids idr, which could lead to double free and memory corruption. This vulnerability could allow an unprivileged local user to induce kernel memory corruption on the system, leading to a crash. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although it is thought to be unlikely. Se ha descubierto una vulnerabilidad en los nombres de espacio de red que afecta al kernel de Linux en versiones anteriores a la 4.14.11. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=21b5944350052d2583e82dd59b19a9ba94a007f0 http://seclists.org/oss-sec/2018/q1/7 http://www.securityfocus.com/bid/102485 https://access.redhat.com/errata/RHSA-2018:0654 https://access.redhat.com/errata/RHSA-2018:0676 https://access.redhat.com/errata/RHSA-2018:1062 https://access.redhat.com/errata/RHSA-2019:1946 https://access.redhat.com/security/cve/CVE-2017-15129 https://bugzilla.redhat.com/show_bug.cgi& • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
