The Windows version of Multipass before 1.7.0 allowed any local process to connect to the localhost TCP control socket to perform mounts from the operating system to a guest, allowing for privilege escalation.
chkstat in SuSE Linux 9.0 through 10.0 allows local users to modify permissions of files by creating a hardlink to a file from a world-writable directory, which can cause the link count to drop to 1 when the file is deleted or replaced, which is then modified by chkstat to use weaker permissions.
StoreBackup before 1.19 does not properly set the uid and guid for symbolic links (1) that are backed up by storeBackup.pl, or (2) recovered by storeBackupRecover.pl, which could cause files to be restored with incorrect ownership.
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.
Linux kernel 2.6.x does not properly restrict socket policy access to users with the CAP_NET_ADMIN capability, which could allow local users to conduct unauthorized activities via (1) ipv4/ip_sockglue.c and (2) ipv6/ipv6_sockglue.c.
A Privilege Escalation vulnerability exits in Fedoraproject Sectool due to an incorrect DBus file.
An out-of-bounds write vulnerability was found in the virtio vhost-user GPU device (vhost-user-gpu) of QEMU in versions up to and including 6.0. The flaw occurs while processing the 'VIRTIO_GPU_CMD_GET_CAPSET' command from the guest. It could allow a privileged guest user to crash the QEMU process on the host, resulting in a denial of service condition, or potential code execution with the privileges of the QEMU process.
apt-setup in Debian GNU/Linux installs the apt.conf file with insecure permissions, which allows local users to obtain sensitive information such as passwords.
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.
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.
The docker-kubic package in SUSE CaaS Platform 3.0 before 17.09.1_ce-7.6.1 provided access to an insecure API locally on the Kubernetes master node.
zgrep in gzip before 1.3.5 does not properly sanitize arguments, which allows local users to execute arbitrary commands via filenames that are injected into a sed script.
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).
Buffer overflow in queue.c in a support script for sympa 3.3.3, when running setuid, allows local users to execute arbitrary code.
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 mysqlaccess script in MySQL 4.0.23 and earlier, 4.1.x before 4.1.10, 5.0.x before 5.0.3, and other versions including 3.x, allows local users to overwrite arbitrary files or read temporary files via a symlink attack on temporary files.
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.

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.)
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).
xscreensaver before 5.14 crashes during activation and leaves the screen unlocked when in Blank Only Mode and when DPMS is disabled, which allows local attackers to access resources without authentication.

KDE before 3.3.0 does not properly handle when certain symbolic links point to "stale" locations, which could allow local users to create or truncate arbitrary files.
An issue was discovered in the Linux kernel 4.18 through 5.10.16, as used by Xen. The backend allocation (aka be-alloc) mode of the drm_xen_front drivers was not meant to be a supported configuration, but this wasn't stated accordingly in its support status entry.
SuSEconfig.javarunt in the javarunt package on SuSE Linux 7.3Pro allows local users to overwrite arbitrary files via a symlink attack on the .java_wrapper temporary file.
SuSEconfig.susewm in the susewm package on SuSE Linux 8.2Pro allows local users to overwrite arbitrary files via a symlink attack on the susewm.$$ temporary file.
It was discovered that a systemd service that uses DynamicUser property can create a SUID/SGID binary that would be allowed to run as the transient service UID/GID even after the service is terminated. A local attacker may use this flaw to access resources that will be owned by a potentially different service in the future, when the UID/GID will be recycled.
The SQLDriverConnect() function in unixODBC before 2.2.14p2 have a possible buffer overflow condition when specifying a large value for SAVEFILE parameter in the connection string.
An issue was discovered in the Linux kernel through 5.11.3. Certain iSCSI data structures do not have appropriate length constraints or checks, and can exceed the PAGE_SIZE value. An unprivileged user can send a Netlink message that is associated with iSCSI, and has a length up to the maximum length of a Netlink message.
In the Linux kernel before 5.2.9, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/usb/misc/yurex.c driver, aka CID-fc05481b2fca.
avahi-daemon-check-dns.sh in the Debian avahi package through 0.8-4 is executed as root via /etc/network/if-up.d/avahi-daemon, and allows a local attacker to cause a denial of service or create arbitrary empty files via a symlink attack on files under /run/avahi-daemon. NOTE: this only affects the packaging for Debian GNU/Linux (used indirectly by SUSE), not the upstream Avahi product.
Buffer overflow in (1) nethack 3.4.0 and earlier, and (2) falconseye 1.9.3 and earlier, which is based on nethack, allows local users to gain privileges via a long -s command line option.
