CVSS: 7.8EPSS: 0%CPEs: 13EXPL: 5CVE-2018-17182 – Linux Kernel - VMA Use-After-Free via Buggy vmacache_flush_all() Fastpath Local Privilege Escalation
https://notcve.org/view.php?id=CVE-2018-17182
19 Sep 2018 — An issue was discovered in the Linux kernel through 4.18.8. The vmacache_flush_all function in mm/vmacache.c mishandles sequence number overflows. An attacker can trigger a use-after-free (and possibly gain privileges) via certain thread creation, map, unmap, invalidation, and dereference operations. Se ha descubierto un problema en el kernel de Linux hasta la versión 4.18.8. La función vmacache_flush_all en mm/vmacache.c manipula incorrectamente los desbordamientos de números de secuencias. • https://www.exploit-db.com/exploits/45497 • CWE-416: Use After Free •

https://notcve.org/view.php?id=CVE-2018-14641
18 Sep 2018 — A security flaw was found in the ip_frag_reasm() function in net/ipv4/ip_fragment.c in the Linux kernel from 4.19-rc1 to 4.19-rc3 inclusive, which can cause a later system crash in ip_do_fragment(). With certain non-default, but non-rare, configuration of a victim host, an attacker can trigger this crash remotely, thus leading to a remote denial-of-service.

11 Sep 2018 — A flaw was found in the way Linux kernel KVM hypervisor before 4.18 emulated instructions such as sgdt/sidt/fxsave/fxrstor. It did not check current privilege(CPL) level while emulating unprivileged instructions. An unprivileged guest user/process could use this flaw to potentially escalate privileges inside guest.

07 Sep 2018 — An issue was discovered in the Linux kernel before 4.18.6. An information leak in cdrom_ioctl_drive_status in drivers/cdrom/cdrom.c could be used by local attackers to read kernel memory because a cast from unsigned long to int interferes with bounds checking. This is similar to CVE-2018-10940. Se ha descubierto un problema en el kernel de Linux hasta antes de la versión 4.18.6.

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.
