kdesktop_lock in kdebase before 3.1.3-5.11 for KDE in Red Hat Enterprise Linux (RHEL) 3 does not properly terminate, which can prevent the screensaver from activating or prevent users from manually locking the desktop.
A flaw was found in Wildfly. An incorrect JBOSS_LOCAL_USER challenge location when using the elytron configuration may lead to JBOSS_LOCAL_USER access to all users on the machine. The highest threat from this vulnerability is to confidentiality, integrity, and availability. This flaw affects wildfly-core versions prior to 17.0.
fontconfig before 2.12.1 does not validate offsets, which allows local users to trigger arbitrary free calls and consequently conduct double free attacks and execute arbitrary code via a crafted cache file.
vim is vulnerable to Heap-based Buffer Overflow
An Elevated Privileges issue exists in JBoss AS 7 Community Release due to the improper implementation in the security context propagation, A threat gets reused from the thread pool that still retains the security context from the process last used, which lets a local user obtain elevated privileges.
udev does not properly set permissions on certain files in /dev/input, which allows local users to obtain sensitive data that is entered at the console, such as user passwords.
It was discovered that the gnome-shell lock screen since version 3.15.91 did not properly restrict all contextual actions. An attacker with physical access to a locked workstation could invoke certain keyboard shortcuts, and potentially other actions.
A Privilege Escalation vulnerability exits in Fedoraproject Sectool due to an incorrect DBus file.
The patch for CVE-2020-17380/CVE-2020-25085 was found to be ineffective, thus making QEMU vulnerable to the out-of-bounds read/write access issues previously found in the SDHCI controller emulation code. This flaw allows a malicious privileged guest to crash the QEMU process on the host, resulting in a denial of service or potential code execution. QEMU up to (including) 5.2.0 is affected by this.
A flaw was found in the Linux kernel in versions prior to 5.10. A violation of memory access was found while detecting a padding of int3 in the linking state. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.
Stack-based buffer overflow in the ieee_putascii function for nasm 0.98 and earlier allows attackers to execute arbitrary code via a crafted asm file, a different vulnerability than CVE-2004-1287.
In the Linux kernel before 5.12.4, net/bluetooth/hci_event.c has a use-after-free when destroying an hci_chan, aka CID-5c4c8c954409. This leads to writing an arbitrary value.
In SaltStack Salt 2016.9 through 3002.6, a command injection vulnerability exists in the snapper module that allows for local privilege escalation on a minion. The attack requires that a file is created with a pathname that is backed up by snapper, and that the master calls the snapper.diff function (which executes popen unsafely).
Yubico pam-u2f before 1.1.1 has a logic issue that, depending on the pam-u2f configuration and the application used, could lead to a local PIN bypass. This issue does not allow user presence (touch) or cryptographic signature verification to be bypassed, so an attacker would still need to physically possess and interact with the YubiKey or another enrolled authenticator. If pam-u2f is configured to require PIN authentication, and the application using pam-u2f allows the user to submit NULL as the PIN, pam-u2f will attempt to perform a FIDO2 authentication without PIN. If this authentication is successful, the PIN requirement is bypassed.
Use after free in Page Info UI in Google Chrome prior to 92.0.4515.131 allowed a remote attacker to potentially exploit heap corruption via physical access to the device.
The KDE screen saver in KDE before 3.0.5 does not properly check the return value from a certain function call, which allows attackers with physical access to cause a crash and access the desktop session.
The alsa-lib package in Red Hat Linux 4 disables stack protection for the libasound.so library, which makes it easier for attackers to execute arbitrary code if there are other vulnerabilities in the library.
IOMMU page mapping issues on x86 T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Both AMD and Intel allow ACPI tables to specify regions of memory which should be left untranslated, which typically means these addresses should pass the translation phase unaltered. While these are typically device specific ACPI properties, they can also be specified to apply to a range of devices, or even all devices. On all systems with such regions Xen failed to prevent guests from undoing/replacing such mappings (CVE-2021-28694). On AMD systems, where a discontinuous range is specified by firmware, the supposedly-excluded middle range will also be identity-mapped (CVE-2021-28695). Further, on AMD systems, upon de-assigment of a physical device from a guest, the identity mappings would be left in place, allowing a guest continued access to ranges of memory which it shouldn't have access to anymore (CVE-2021-28696).
An issue was discovered in the Linux kernel through 5.11.8. The sound/soc/qcom/sdm845.c soundwire device driver has a buffer overflow when an unexpected port ID number is encountered, aka CID-1c668e1c0a0f. (This has been fixed in 5.12-rc4.)

tcpdump does not properly drop privileges to the pcap user when starting up.
udisks before 1.0.3 allows a local user to load arbitrary Linux kernel modules.
Safe.pm 2.0.7 and earlier, when used in Perl 5.8.0 and earlier, may allow attackers to break out of safe compartments in (1) Safe::reval or (2) Safe::rdo using a redefined @_ variable, which is not reset between successive calls.
Buffer overflow in efstools in Bonobo, when installed setuid, allows local users to execute arbitrary code via long command line arguments.
The default stylesheet for DocBook on Red Hat Linux 6.2 through 7.2 is installed with an insecure option enabled, which could allow users to overwrite files outside of the current directory from an untrusted document by using a full pathname as an element identifier.
The cluster logical volume manager daemon (clvmd) in lvm2-cluster in LVM2 before 2.02.72, as used in Red Hat Global File System (GFS) and other products, does not verify client credentials upon a socket connection, which allows local users to cause a denial of service (daemon exit or logical-volume change) or possibly have unspecified other impact via crafted control commands.
