A local attacker with special user privilege could crash the system leading to information leak. The highest threat from this vulnerability is to da...

UBUNTU-CVE-2021-26932

An issue was discovered in the Linux kernel 3.2 through 5.10.16, as used by Xen. Grant mapping operations often occur in batch hypercalls, where a number of operations are done in a single hypercall, the success or failure of each one is reported to the backend driver, and the backend driver then...

kernel: ICMP rate limiting can be used for DNS poisoning attack

A flaw in the way reply ICMP packets are limited in the Linux kernel functionality was found that allows to quickly scan open UDP ports. This flaw allows an off-path remote user to effectively bypassing source port UDP randomization. The highest threat from this vulnerability is to confidentialit...

kernel: Nfsd failure to clear umask after processing an open or create

A flaw incorrect umask during file or directory modification in the Linux kernel NFS network file system functionality was found in the way user create and delete object using NFSv4.2 or newer if both simultaneously accessing the NFS by the other process that is not using new NFSv4.2. A user with...

UBUNTU-CVE-2021-1052

NVIDIA GPU Display Driver for Windows and Linux, all versions, contains a vulnerability in the kernel mode layer nvlddmkm.sys handler for DxgkDdiEscape or IOCTL in which user-mode clients can access legacy privileged APIs, which may lead to denial of service, escalation of privileges, and...

Design/Logic Flaw

A use-after-free flaw was found in kernel/trace/ringbuffer.c in Linux kernel before 5.10-rc1. There was a race problem in traceopen and resize of cpu buffer running parallely on different cpus, may cause a denial of service problem DOS. This flaw could even allow a local attacker with special use...

EUVD-2020-20288

A flaw was found in the Linux kernel’s implementation of MIDI, where an attacker with a local account and the permissions to issue ioctl commands to midi devices could trigger a use-after-free issue. A write to this specific memory while freed and before use causes the flow of execution to change...

kernel: soft-lockups in iov_iter_copy_from_user_atomic() could result in DoS

A flaw was found in the Linux kernel’s implementation of biovecs. A zero-length biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block device,...

DEBIAN-CVE-2020-14351

A flaw was found in the Linux kernel. A use-after-free memory flaw was found in the perf subsystem allowing a local attacker with permission to monitor perf events to corrupt memory and possibly escalate privileges. The highest threat from this vulnerability is to data confidentiality and integri...

CVE-2020-14381

A flaw was found in the Linux kernel’s futex implementation. This flaw allows a local attacker to corrupt system memory or escalate their privileges when creating a futex on a filesystem that is about to be unmounted. The highest threat from this vulnerability is to confidentiality, integrity, as...

CVE-2020-25705

A flaw in ICMP packets in the Linux kernel may allow an attacker to quickly scan open UDP ports. This flaw allows an off-path remote attacker to effectively bypass source port UDP randomization. Software that relies on UDP source port randomization are indirectly affected as well on the Linux Bas...

kernel: net-sysfs: *_queue_add_kobject refcount issue

A flaw was found in the way the rxqueueaddkobject and netdevqueueaddkobject functions in the Linux kernel handled refcounting of certain objects. This flaw allows a local user who can trigger the error code path to use this vulnerability to disturb the integrity of the system...

kernel: bad kfree in auditfilter.c may lead to escalation of privilege

A flaw was found in the Linux kernel. A logic error in auditdatatoentry can lead to a local escalation of privilege without user interaction needed. A local attacker with special user privilege could crash the system leading to information leak. The highest threat from this vulnerability is to da...

kernel: sync of excessive duration via an XFS v5 image with crafted metadata

A flaw was discovered in the XFS source in the Linux kernel. This flaw allows an attacker with the ability to mount an XFS filesystem, to trigger a denial of service while attempting to sync a file located on an XFS v5 image with crafted metadata...

kernel: possible to send arbitrary signals to a privileged (suidroot) parent process

A flaw was found in the Linux kernel loose validation of child/parent process identification handling while filtering signal handlers. A local attacker is able to abuse this flaw to bypass checks to send any signal to a privileged process...

kernel: out-of-bounds write via crafted keycode table

An out-of-bounds write flaw was found in the Linux kernel. A crafted keycode table could be used by drivers/input/input.c to perform the out-of-bounds write. A local user with root access can insert garbage to this keycode table that can lead to out-of-bounds memory access. The highest threat fro...
