CVE-2019-19059

Status Candidate

Overview

Multiple memory leaks in the iwl_pcie_ctxt_info_gen3_init() function in drivers/net/wireless/intel/iwlwifi/pcie/ctxt-info-gen3.c in the Linux kernel through 5.3.11 allow attackers to cause a denial of service (memory consumption) by triggering iwl_pcie_init_fw_sec() or dma_alloc_coherent() failures, aka CID-0f4f199443fa.

Red Hat Security Advisory 2020-4062-01 - The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Issues addressed include buffer overflow, bypass, denial of service, information leakage, memory leak, null pointer, out of bounds read, out of bounds write, privilege escalation, and use-after-free vulnerabilities.

Ubuntu Security Notice USN-4301-1
Posted Mar 17, 2020
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 4301-1 - It was discovered that the KVM implementation in the Linux kernel, when paravirtual TLB flushes are enabled in guests, the hypervisor in some situations could miss deferred TLB flushes or otherwise mishandle them. An attacker in a guest VM could use this to expose sensitive information. Paulo Bonzini discovered that the KVM hypervisor implementation in the Linux kernel could improperly let a nested guest access the resources of a parent guest in certain situations. An attacker could use this to expose sensitive information. Various other issues were also addressed.
