The SCTP socket buffer used by a userspace application is not accounted by the cgroups subsystem. An attacker can use this flaw to cause a denial of service attack. Kernel 3.10.x and 4.18.x branches are believed to be vulnerable.
CVE-2019-11599 1 Linux 1 Linux Kernel 2021-06-14 6.9 MEDIUM 7.0 HIGH
The coredump implementation in the Linux kernel before 5.0.10 does not use locking or other mechanisms to prevent vma layout or vma flags changes while it runs, which allows local users to obtain sensitive information, cause a denial of service, or possibly have unspecified other impact by triggering a race condition with mmget_not_zero or get_task_mm calls. This is related to fs/userfaultfd.c, mm/mmap.c, fs/proc/task_mmu.c, and drivers/infiniband/core/uverbs_main.c.
CVE-2019-19052 1 Linux 1 Linux Kernel 2021-06-14 7.8 HIGH 7.5 HIGH
A memory leak in the gs_can_open() function in drivers/net/can/usb/gs_usb.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usb_submit_urb() failures, aka CID-fb5be6a7b486.
CVE-2019-17075 1 Linux 1 Linux Kernel 2021-06-14 7.1 HIGH 7.5 HIGH
An issue was discovered in write_tpt_entry in drivers/infiniband/hw/cxgb4/mem.c in the Linux kernel through 5.3.2. The cxgb4 driver is directly calling dma_map_single (a DMA function) from a stack variable. This could allow an attacker to trigger a Denial of Service, exploitable if this driver is used on an architecture for which this stack/DMA interaction has security relevance.
CVE-2019-19922 1 Linux 1 Linux Kernel 2021-06-14 2.1 LOW 5.5 MEDIUM
kernel/sched/fair.c in the Linux kernel before 5.3.9, when cpu.cfs_quota_us is used (e.g., with Kubernetes), allows attackers to cause a denial of service against non-cpu-bound applications by generating a workload that triggers unwanted slice expiration, aka CID-de53fd7aedb1. (In other words, although this slice expiration would typically be seen with benign workloads, it is possible that an attacker could calculate how many stray requests are required to force an entire Kubernetes cluster into a low-performance state caused by slice expiration, and ensure that a DDoS attack sent that number of stray requests. An attack does not affect the stability of the kernel; it only causes mismanagement of application execution.)
CVE-2019-10639 1 Linux 1 Linux Kernel 2021-06-14 5.0 MEDIUM 7.5 HIGH
The Linux kernel 4.x (starting from 4.1) and 5.x before 5.0.8 allows Information Exposure (partial kernel address disclosure), leading to a KASLR bypass. Specifically, it is possible to extract the KASLR kernel image offset using the IP ID values the kernel produces for connection-less protocols (e.g., UDP and ICMP). When such traffic is sent to multiple destination IP addresses, it is possible to obtain hash collisions (of indices to the counter array) and thereby obtain the hashing key (via enumeration). This key contains enough bits from a kernel address (of a static variable) so when the key is extracted (via enumeration), the offset of the kernel image is exposed. This attack can be carried out remotely, by the attacker forcing the target device to send UDP or ICMP (or certain other) traffic to attacker-controlled IP addresses. Forcing a server to send UDP traffic is trivial if the server is a DNS server. ICMP traffic is trivial if the server answers ICMP Echo requests (ping). For client targets, if the target visits the attacker's web page, then WebRTC or gQUIC can be used to force UDP traffic to attacker-controlled IP addresses. NOTE: this attack against KASLR became viable in 4.1 because IP ID generation was changed to have a dependency on an address associated with a network namespace.
CVE-2020-24394 3 Canonical, Linux, Opensuse 3 Ubuntu Linux, Linux Kernel, Leap 2021-06-14 3.6 LOW 7.1 HIGH
In the Linux kernel before 5.7.8, fs/nfsd/vfs.c (in the NFS server) can set incorrect permissions on new filesystem objects when the filesystem lacks ACL support, aka CID-22cf8419f131. This occurs because the current umask is not considered.
CVE-2020-12114 1 Linux 1 Linux Kernel 2021-06-14 1.9 LOW 4.7 MEDIUM
A pivot_root race condition in fs/namespace.c in the Linux kernel 4.4.x before 4.4.221, 4.9.x before 4.9.221, 4.14.x before 4.14.178, 4.19.x before 4.19.119, and 5.x before 5.3 allows local users to cause a denial of service (panic) by corrupting a mountpoint reference counter.
CVE-2014-4806 2 Ibm, Linux 2 Security Appscan, Linux Kernel 2021-06-11 2.1 LOW 5.5 MEDIUM
The installation process in IBM Security AppScan Enterprise 8.x before 8.6.0.2 iFix 003, 8.7.x before 8.7.0.1 iFix 003, 8.8.x before 8.8.0.1 iFix 002, and 9.0.x before 9.0.0.1 iFix 001 on Linux places a cleartext password in a temporary file, which allows local users to obtain sensitive information by reading this file.
CVE-2020-10742 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2021-06-11 3.6 LOW 6.0 MEDIUM
A flaw was found in the Linux kernel. An index buffer overflow during Direct IO write leading to the NFS client to crash. In some cases, a reach out of the index after one memory allocation by kmalloc will cause a kernel panic. The highest threat from this vulnerability is to data confidentiality and system availability.
