27 Oct 2018 — An issue was discovered in the Linux kernel through 4.19. An information leak in cdrom_ioctl_select_disc 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 and CVE-2018-16658. Se ha descubierto un problema en el kernel de Linux hasta la versión 4.19.

26 Oct 2018 — In the Linux kernel before 4.17, a local attacker able to set attributes on an xfs filesystem could make this filesystem non-operational until the next mount by triggering an unchecked error condition during an xfs attribute change, because xfs_attr_shortform_addname in fs/xfs/libxfs/xfs_attr.c mishandles ATTR_REPLACE operations with conversion of an attr from short to long form.

17 Oct 2018 — In the Linux kernel 4.14.x, 4.15.x, 4.16.x, 4.17.x, and 4.18.x before 4.18.13, faulty computation of numeric bounds in the BPF verifier permits out-of-bounds memory accesses because adjust_scalar_min_max_vals in kernel/bpf/verifier.c mishandles 32-bit right shifts. En el kernel de Linux 4.14.x, 4.15.x, 4.16.x, 4.17.x y versiones 4.18.x anteriores a la 4.18.13, el cálculo incorrecto de enlaces numéricos en el verificador BPF permite accesos a la memoria fuera de límites debido a que adjust_scalar_min_max_val... • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=b799207e1e1816b09e7a5920fbb2d5fcf6edd681 • CWE-125: Out-of-bounds Read •

08 Oct 2018 — A missing address check in the callers of the show_opcodes() in the Linux kernel allows an attacker to dump the kernel memory at an arbitrary kernel address into the dmesg log. La falta de una comprobación de direcciones en los llamantes de show_opcodes() en el kernel de Linux permite que un atacante vuelque la memoria del kernel en una dirección arbitraria del kernel en el registro dmesg. • http://www.securitytracker.com/id/1041804 • CWE-20: Improper Input Validation •

07 Oct 2018 — arch/arm64/kvm/guest.c in KVM in the Linux kernel before 4.18.12 on the arm64 platform mishandles the KVM_SET_ON_REG ioctl. This is exploitable by attackers who can create virtual machines. An attacker can arbitrarily redirect the hypervisor flow of control (with full register control). An attacker can also cause a denial of service (hypervisor panic) via an illegal exception return. This occurs because of insufficient restrictions on userspace access to the core register file, and because PSTATE.M validati... • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=2a3f93459d689d990b3ecfbe782fec89b97d3279 • CWE-20: Improper Input Validation •

25 Sep 2018 — A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host.
