Canonical: Security Vulnerabilities
It was discovered that a systemd service that uses DynamicUser property can get new privileges through the execution of SUID binaries, which would allow to create binaries owned by the service transient group with the setgid bit set. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the GID will be recycled.

An infinite loop issue was found in the vhost_net kernel module in Linux Kernel up to and including v5.1-rc6, while handling incoming packets in handle_rx(). It could occur if one end sends packets faster than the other end can process them. A guest user, maybe remote one, could use this flaw to stall the vhost_net kernel thread, resulting in a DoS scenario.

In GraphicsMagick from version 1.3.30 to 1.4 snapshot-20190403 Q8, there is a heap-based buffer overflow in the function WriteMATLABImage of coders/mat.c, which allows an attacker to cause a denial of service or possibly have unspecified other impact via a crafted image file. This is related to ExportRedQuantumType in magick/export.c.

snap-confine in snapd before 2.38 incorrectly set the ownership of a snap application to the uid and gid of the first calling user. Consequently, that user had unintended access to a private /tmp directory.

snap-confine as included in snapd before 2.39 did not guard against symlink races when performing the chdir() to the current working directory of the calling user, aka a "cwd restore permission bypass."

In GraphicsMagick from version 1.3.8 to 1.4 snapshot-20190403 Q8, there is a heap-based buffer overflow in the function WritePDBImage of coders/pdb.c, which allows an attacker to cause a denial of service or possibly have unspecified other impact via a crafted image file. This is related to MagickBitStreamMSBWrite in magick/bit_stream.c.

A flaw was found in the Linux kernel's vfio interface implementation that permits violation of the user's locked memory limit. If a device is bound to a vfio driver, such as vfio-pci, and the local attacker is administratively granted ownership of the device, it may cause a system memory exhaustion and thus a denial of service (DoS). Versions 3.10, 4.14 and 4.18 are vulnerable.

WavpackSetConfiguration64 in pack_utils.c in libwavpack.a in WavPack through 5.1.0 has a "Conditional jump or move depends on uninitialised value" condition, which might allow attackers to cause a denial of service (application crash) via a DFF file that lacks valid sample-rate data.

The Linux kernel before 5.1-rc5 allows page->_refcount reference count overflow, with resultant use-after-free issues, if about 140 GiB of RAM exists. This is related to fs/fuse/dev.c, fs/pipe.c, fs/splice.c, include/linux/mm.h, include/linux/pipe_fs_i.h, kernel/trace/trace.c, mm/gup.c, and mm/hugetlb.c. It can occur with FUSE requests.
