A local user can exploit this by providing a specially crafted, excessively long input to the `polkit-agent-helper-1` setuid binary via standard input (stdin). This unbounded input can lead to an out-of-memory (OOM) condition, resulting in a Denial of Service (DoS) for the system. Scope: local bookworm: open bullseye: open forky: open

CVE-2025-7519 [MEDIUM] CVE-2025-7519: policykit-1 - A flaw was found in polkit. When processing an XML policy with 32 or more nested... A flaw was found in polkit. When processing an XML policy with 32 or more nested elements in depth, an out-of-bounds write can be triggered. This issue can lead to a crash or other unexpected behavior, and arbitrary code execution is not discarded. To exploit this flaw, a high-privilege account is needed as it's required to place the malicious policy file proper

CVE-2021-3560 [HIGH] CVE-2021-3560: policykit-1 - It was found that polkit could be tricked into bypassing the credential checks f... It was found that polkit could be tricked into bypassing the credential checks for D-Bus requests, elevating the privileges of the requestor to the root user. This flaw could be used by an unprivileged local attacker to, for example, create a new local administrator. The highest threat from this vulnerability is to data confidentiality and integrity as well as sys

CVE-2021-4034 [HIGH] CVE-2021-4034: policykit-1 - A local privilege escalation vulnerability was found on polkit's pkexec utility.... A local privilege escalation vulnerability was found on polkit's pkexec utility. The pkexec application is a setuid tool designed to allow unprivileged users to run commands as privileged users according predefined policies. The current version of pkexec doesn't handle the calling parameters count correctly and ends trying to execute environment variables as comma

There is a flaw in polkit which can allow an unprivileged user to cause polkit to crash, due to process file descriptor exhaustion. The highest threat from this vulnerability is to availability. NOTE: Polkit process outage duration is tied to the failing process being reaped and a new one being spawned Scope: local bookworm: resolved (fixed in 0.105-32) bullseye

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. Scope: local bookworm: resolved (fixed in 4.19.16-1) bullseye: resolved (fixed in 4.19.16-1) forky
