In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfsbtrfsioctlfdreplace() calls fdget(oldfd), then without further checks passes the resulting file into shiftfsrealfdget(), which casts file->privatedata, a void that points to a filesystem-dependent type, to a "struct shiftfsfileinfo ". As the privatedata is not required to be a pointer, an attacker can use this to cause a denial of service or possibly execute arbitrary code.
In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, several locations which shift ids translate user/group ids before performing operations in the lower filesystem were translating them into inituserns, whereas they should have been translated into the suserns for the lower filesystem. This resulted in using ids other than the intended ones in the lower fs, which likely did not map into the shifts suserns. A local attacker could use this to possibly bypass discretionary access control permissions.
In shiftfs, a non-upstream patch to the Linux kernel included in the Ubuntu 5.0 and 5.3 kernel series, shiftfsbtrfsioctlfdreplace() installs an fd referencing a file from the lower filesystem without taking an additional reference to that file. After the btrfs ioctl completes this fd is closed, which then puts a reference to that file, leading to a refcount underflow.

Due to a missing case handling object types, a type confusion vulnerability could occur, resulting in a crash. We presume that with enough effort that it could be exploited to run arbitrary code.

An issue was discovered in Squid 3.x and 4.x through 4.8. Due to incorrect input validation, there is a heap-based buffer overflow that can result in Denial of Service to all clients using the proxy. Severity is high due to this vulnerability occurring before normal security checks; any remote client that can reach the proxy port can trivially perform the attack via a crafted URI scheme.
An issue was discovered in Squid 2.x, 3.x, and 4.x through 4.8. Due to incorrect data management, it is vulnerable to information disclosure when processing HTTP Digest Authentication. Nonce tokens contain the raw byte value of a pointer that sits within heap memory allocation. This information reduces ASLR protections and may aid attackers isolating memory areas to target for remote code execution attacks.

A memory leak in the ca8210probe() function in drivers/net/ieee802154/ca8210.c in the Linux kernel before 5.3.8 allows attackers to cause a denial of service (memory consumption) by triggering ca8210getplatformdata() failures, aka CID-6402939ec86e.
A memory leak in the adisupdatescanmode() function in drivers/iio/imu/adisbuffer.c in the Linux kernel before 5.3.9 allows attackers to cause a denial of service (memory consumption), aka CID-ab612b1daf41.
A memory leak in the gscanopen() function in drivers/net/can/usb/gsusb.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption) by triggering usbsubmiturb() failures, aka CID-fb5be6a7b486.
A memory leak in the dwc3pciprobe() function in drivers/usb/dwc3/dwc3-pci.c in the Linux kernel through 5.3.9 allows attackers to cause a denial of service (memory consumption) by triggering platformdeviceaddproperties() failures, aka CID-9bbfceea12a8.
DjVuLibre 3.5.27 has a NULL pointer dereference in the function DJVU::filterfv at IW44EncodeCodec.cpp.
In bindertransaction of binder.c, there is a possible out of bounds write due to a missing bounds check.

archivereadformatrarreaddata in archivereadsupportformatrar.c in libarchive before 3.4.0 has a use-after-free in a certain ARCHIVEFAILED situation, related to Ppmd7DecodeSymbol.
cdfreadpropertyinfo in cdf.c in file through 5.37 does not restrict the number of CDFVECTOR elements, which allows a heap-based buffer overflow (4-byte out-of-bounds write).
A vulnerabiliy was found in xsltCopyText in transform.c in libxslt 1.1.33, a pointer variable isn't reset under certain circumstances. If the relevant memory area happened to be freed and reused in a certain way, a bounds check could fail and memory outside a buffer could be written to, or uninitialized data could be disclosed.

A flaw was found in the Linux kernel's implementation of the RealTek wireless drivers WiFi-direct (or WiFi peer-to-peer) driver implementation. When the RealTek wireless networking hardware is configured to accept WiFi-Direct or WiFi P2P connections, an attacker within the wireless network connectivity radio range can exploit a flaw in the WiFi-direct protocol known as "Notice of Absence" by creating specially crafted frames which can then corrupt kernel memory as the upper bounds on the length of the frame is unchecked and supplied by the incoming packet.

A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue buffers to IOVs logged the buffer descriptors during migration. A privileged guest user able to pass descriptors with invalid length to the host when migration is underway, could use this flaw to increase their privileges on the host.
