A flaw was found in how the ACPI table loading through the EFI variable (and the related efivarssdt boot option) was handled when the Linux kernel was locked down. This flaw allows a (root) privileged local user to circumvent the kernel lockdown restrictions. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.

A vulnerability was discovered in gdm before 3.31.4. When timed login is enabled in configuration, an attacker could bypass the lock screen by selecting the timed login user and waiting for the timer to expire, at which time they would gain access to the logged-in user's session.
In the Linux kernel before 5.3.11, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/net/can/usb/mcbausb.c driver, aka CID-4d6636498c41.
An issue was discovered in the Linux kernel before 5.0.10. There is a use-after-free in the sound subsystem because card disconnection causes certain data structures to be deleted too early. This is related to sound/core/init.c and sound/core/info.c.
An out-of-bound write access flaw was found in the way QEMU loads ROM contents at boot time. This flaw occurs in the romcopy() routine while loading the contents of a 32-bit -kernel image into memory. Running an untrusted -kernel image may load contents at arbitrary memory locations, potentially leading to code execution with the privileges of the QEMU process.
It was discovered that the Kerberos implementation in the Security component of OpenJDK used RSA-MD5 checksum in Ticket Granting Service (TGS) requests even though MD5 algorithm is no longer considered safe for such use case. A remote attacker could possibly use this flaw to manipulate TGS requests.
A flaw was found in the way the Ceph RGW Beast front-end handles unexpected disconnects. An authenticated attacker can abuse this flaw by making multiple disconnect attempts resulting in a permanent leak of a socket connection by radosgw. This flaw could lead to a denial of service condition by pile up of CLOSEWAIT sockets, eventually leading to the exhaustion of available resources, preventing legitimate users from connecting to the system.
An issue was discovered in OpenSSH 7.9. Due to missing character encoding in the progress display, a malicious server (or Man-in-The-Middle attacker) can employ crafted object names to manipulate the client output, e.g., by using ANSI control codes to hide additional files being transferred. This affects refreshprogressmeter() in progressmeter.c.
A vulnerability was found in sgwrite in drivers/scsi/sg.c in SCSI generic (sg) driver subsystem. An attacker with a local access and special user privilege (or root) can cause a denial of service (DoS) if allocated list is not cleaned with invalid (Sgfd sfp) pointer at the time of failure, failing this can even cause a kernel internal information leak problem.

A flaw was found in how the ACPI table loading through acpiconfigfs was handled when the kernel was locked down. This flaw allows a (root) privileged local user to circumvent the kernel lockdown restrictions. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
A vulnerability was found in DPDK through version 18.11, vhostusersetlogbase() is a message handler that is called to handle the VHOSTUSERSETLOGBASE message. Its payload contains a 64 bit size and offset. Both are added up and used as a size when calling mmap(). There is no integer overflow check. If an integer overflow occurs a smaller memory map would be created than requested. Since the returned mapping is mapped as writable and used for logging, it seems highly likely that memory corruption can occur.
A memory corruption issue was found in DPDK versions 17.05 and above
In PolicyKit (aka polkit) 0.115, the "start time" protection mechanism can be bypassed because fork() is not atomic, and therefore authorization decisions are improperly cached. This is related to lack of uid checking in polkitbackend/polkitbackendinteractiveauthority.c.

Inappropriate implementation in WebRTC in Google Chrome prior to 84.0.4147.89 allowed an attacker in a privileged network position to potentially exploit heap corruption via a crafted SCTP stream.
In Django 1.11.x before 1.11.18, 2.0.x before 2.0.10, and 2.1.x before 2.1.5, an Improper Neutralization of Special Elements in Output Used by a Downstream Component issue exists in django.views.defaults.pagenotfound(), leading to content spoofing (in a 404 error page) if a user fails to recognize that a crafted URL has malicious content.
A protocol downgrade flaw was found in Network Security Services (NSS). After a HelloRetryRequest has been sent, the client may negotiate a lower protocol than TLS 1.3, resulting in an invalid state transition in the TLS State Machine. If the client gets into this state, incoming Application Data records will be ignored.
If an XML file is served with a Content Security Policy and the XML file includes an XSL stylesheet, the Content Security Policy will not be applied to the contents of the XSL stylesheet. If the XSL sheet e.g. includes JavaScript, it would bypass any of the restrictions of the Content Security Policy applied to the XML document.
A vulnerability where a WebExtension can run content scripts in disallowed contexts following navigation or other events. This allows for potential privilege escalation by the WebExtension on sites where content scripts should not be run.
By using the reflected URL in some special resource URIs, such as chrome:, it is possible to inject stylesheets and bypass Content Security Policy (CSP).

A compromised IPC child process can escape the content sandbox and list the names of arbitrary files on the file system without user consent or interaction. This could result in exposure of private local files.
An invalid grid size during QCMS (color profile) transformations can result in the out-of-bounds read interpreted as a float value. This could leak private data into the output.
A flaw was found in Mozilla Thunderbird before version 52.9. Decrypted S/MIME parts hidden with CSS or <plaintext> can leak plaintext when included in a HTML reply/forward.

A redirected HTTP request which is observed or modified through a web extension could bypass existing CORS checks, leading to potential disclosure of cross-origin information. This vulnerability affects Firefox ESR < 78.1, Firefox < 79, and Thunderbird < 78.1.
By observing the stack trace for JavaScript errors in web workers, it was possible to leak the result of a cross-origin redirect. This applied only to content that can be parsed as script.
