Race condition in backend/ctrl.c in KDM in KDE Software Compilation (SC) 2.2.0 through 4.4.2 allows local users to change the permissions of arbitrary files, and consequently gain privileges, by blocking the removal of a certain directory that contains a control socket, related to improper interaction with ksm.
KDE kdelibs before 4.14 and kauth before 5.1 does not properly use D-Bus for communication with a polkit authority, which allows local users to bypass intended access restrictions by leveraging a PolkitUnixProcess PolkitSubject race condition via a (1) setuid process or (2) pkexec process, related to CVE-2013-4288 and "PID reuse race conditions."
kcheckpass passes a user-supplied argument to the pam_start function, often within a setuid environment, which allows local users to invoke any configured PAM stack, and possibly trigger unintended side effects, via an arbitrary valid PAM service name, a different vulnerability than CVE-2011-4122. NOTE: the vendor indicates that the possibility of resultant privilege escalation may be "a bit far-fetched."
aRts 1.5.10 and kdelibs3 3.5.10 and earlier do not properly create temporary directories, which allows local users to hijack the IPC by pre-creating the temporary directory.
KDE KCron through 21.12.2 uses a temporary file in /tmp when saving, but reuses the filename during an editing session. Thus, someone watching it be created the first time could potentially intercept the file the following time, enabling that person to run unauthorized commands.
mountall.c in mountall before 2.15.2 uses 0666 permissions for the root.rules file, which allows local users to gain privileges by modifying this file.
In easelcomm_hw_build_scatterlist, there is a possible out of bounds write due to a race condition. This could lead to local escalation of privilege with System privileges required. User interaction is not needed for exploitation. Product: Android. Versions: Android kernel. Android ID: A-69808833.

Race condition in the installation package in Apple iTunes before 9.1 on Windows allows local users to gain privileges by replacing an unspecified file with a Trojan horse.
An issue was discovered in Xen through 4.13.x, allowing guest OS users to cause a denial of service or possibly gain privileges because of missing memory barriers in read-write unlock paths. The read-write unlock paths don't contain a memory barrier. On Arm, this means a processor is allowed to re-order the memory access with the preceding ones. In other words, the unlock may be seen by another processor before all the memory accesses within the "critical" section. As a consequence, it may be possible to have a writer executing a critical section at the same time as readers or another writer. In other words, many of the assumptions (e.g., a variable cannot be modified after a check) in the critical sections are not safe anymore. The read-write locks are used in hypercalls (such as grant-table ones), so a malicious guest could exploit the race. For instance, there is a small window where Xen can leak memory if XENMAPSPACE_grant_table is used concurrently. A malicious guest may be able to leak memory, or cause a hypervisor crash resulting in a Denial of Service (DoS). Information leak and privilege escalation cannot be excluded.
An issue was discovered in secdrv.sys as shipped in Microsoft Windows Vista, Windows 7, Windows 8, and Windows 8.1 before KB3086255, and as shipped in Macrovision SafeDisc.

A Time-of-Check Time-of-Use privilege escalation vulnerability in Trend Micro Maximum Security (Consumer) 2018 could allow a local attacker to escalate privileges on vulnerable installations due to a flaw within processing of IOCTL 0x222813 by the tmusa driver. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
An issue was discovered in the __ns_get_path function in fs/nsfs.c in the Linux kernel before 4.11. Due to a race condition when accessing files, a Use After Free condition can occur.

In blk_mq_tag_to_rq in blk-mq.c in the upstream kernel, there is a possible use after free due to a race condition when a request has been previously freed by blk_mq_complete_request. This could lead to local escalation of privilege. Product: Android. Versions: Android kernel. Android ID: A-63083046.
In the Linux Kernel before version 4.16.11, 4.14.43, 4.9.102, and 4.4.133, multiple race condition errors when handling probe, disconnect, and rebind operations can be exploited to trigger a use-after-free condition or a NULL pointer dereference by sending multiple USB over IP packets.
In the Easel driver, there is possible memory corruption due to race conditions. This could lead to local escalation of privilege with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-112309571
Race condition in the Doors subsystem in the kernel in Sun Solaris 8 through 10, and OpenSolaris before snv_94, allows local users to cause a denial of service (process hang), or possibly bypass file permissions or gain kernel-context privileges, via vectors involving the time at which control is transferred from a caller to a door server.
The SHA-2 digest support in the sudoers plugin in sudo after 1.8.7 allows local users with write permissions to parts of the called command to replace them before it is executed.
.A flaw was found in the CAN BCM networking protocol in the Linux kernel, where a local attacker can abuse a flaw in the CAN subsystem to corrupt memory, crash the system or escalate privileges. This race condition in net/can/bcm.c in the Linux kernel allows for local privilege escalation to root.
A use-after-free in function hci_sock_bound_ioctl() of the Linux kernel HCI subsystem was found in the way user calls ioct HCIUNBLOCKADDR or other way triggers race condition of the call hci_unregister_dev() together with one of the calls hci_sock_blacklist_add(), hci_sock_blacklist_del(), hci_get_conn_info(), hci_get_auth_info(). A privileged local user could use this flaw to crash the system or escalate their privileges on the system. This flaw affects the Linux kernel versions prior to 5.13-rc5.
A flaw use-after-free in function sco_sock_sendmsg() of the Linux kernel HCI subsystem was found in the way user calls ioct UFFDIO_REGISTER or other way triggers race condition of the call sco_conn_del() together with the call sco_sock_sendmsg() with the expected controllable faulting memory page. A privileged local user could use this flaw to crash the system or escalate their privileges on the system.
An issue was discovered in CapMon Access Manager 5.4.1.1005. CALRunElevated.exe attempts to enforce access control by adding an unprivileged user to the local Administrators group for a very short time to execute a single command. However, the user is left in that group if the command crashes, and there is also a race condition in all cases.

The Btrfs implementation in the Linux kernel before 3.19 does not ensure that the visible xattr state is consistent with a requested replacement, which allows local users to bypass intended ACL settings and gain privileges via standard filesystem operations (1) during an xattr-replacement time window, related to a race condition, or (2) after an xattr-replacement attempt that fails because the data does not fit.
Race condition in the rmtree function in File::Path 1.08 (lib/File/Path.pm) in Perl 5.8.8 allows local users to to delete arbitrary files via a symlink attack, a different vulnerability than CVE-2005-0448, CVE-2004-0452, and CVE-2008-2827. NOTE: this is a regression error related to CVE-2005-0448. It is different from CVE-2008-5302 due to affected versions.
Race condition in the key_gc_unused_keys function in security/keys/gc.c in the Linux kernel through 3.18.2 allows local users to cause a denial of service (memory corruption or panic) or possibly have unspecified other impact via keyctl commands that trigger access to a key structure member during garbage collection of a key.

NOTE: this is a regression error related to CVE-2005-0448. It is different from CVE-2008-5303 due to affected versions.
Race condition in the lockscreen feature in Mozilla Firefox OS before 2.5 allows physically proximate attackers to bypass an intended passcode requirement via unspecified vectors.
Race condition in the bindBackupAgent method in the ActivityManagerService in Android 4.4.4 allows local users with adb shell access to execute arbitrary code or any valid package as system by running "pm install" with the target apk, and simultaneously running a crafted script to process logcat's output looking for a dexopt line, which once found should execute bindBackupAgent with the uid member of the ApplicationInfo parameter set to 1000.
Possible race condition during async fastrpc session after sending RPC message due to the fastrpc ctx gets free during async session in Snapdragon Compute, Snapdragon Industrial IOT, Snapdragon Mobile
Race condition in NVMap in NVIDIA Tegra Linux Kernel 3.10 allows local users to gain privileges via a crafted NVMAP_IOC_CREATE IOCTL call, which triggers a use-after-free error, as demonstrated by using a race condition to escape the Chrome sandbox.
Race condition in the client in IBM Tivoli Storage Manager (TSM) 5.4.0.0 through 5.4.3.6, 5.5.0.0 through 5.5.4.3, 6.1.0.0 through 6.1.5.6, 6.2 before 6.2.5.4, 6.3 before 6.3.2.3, 6.4 before 6.4.2.1, and 7.1 before 7.1.1 on UNIX and Linux allows local users to obtain root privileges via unspecified vectors.

A race condition in the wmi_malware_scan.nbin plugin before 201402262215 for Nessus 5.2.1 allows local users to gain privileges by replacing the dissolvable agent executable in the Windows temp directory with a Trojan horse program.
init_tmp in TeeJee.FileSystem.vala in Timeshift before 20.03 unsafely reuses a preexisting temporary directory in the predictable location /tmp/timeshift. It follows symlinks in this location or uses directories owned by unprivileged users. Because Timeshift also executes scripts under this location, an attacker can attempt to win a race condition to replace scripts created by Timeshift with attacker-controlled scripts. Upon success, an attacker-controlled script is executed with full root privileges. This logic is practically always triggered when Timeshift runs regardless of the command-line arguments used.
A race condition in Linux kernel SCTP sockets (net/sctp/socket.c) before 5.12-rc8 can lead to kernel privilege escalation from the context of a network service or an unprivileged process. If sctp_destroy_sock is called without sock_net(sk)->sctp.addr_wq_lock then an element is removed from the auto_asconf_splist list without any proper locking. This can be exploited by an attacker with network service privileges to escalate to root or from the context of an unprivileged user directly if a BPF_CGROUP_INET_SOCK_CREATE is attached which denies creation of some SCTP socket.
Race condition in the power policy functions in policy-funcs in acpi-support before 0.142 allows local users to gain privileges via unspecified vectors.
The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the "LECHO & !OPOST" case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings.
Insufficient policy enforcement in Cryptohome in Google Chrome prior to 88.0.4324.96 allowed a local attacker to perform OS-level privilege escalation via a crafted file.
