CVE-2026-12388

CVE-2026-12388 affects Keycloak’s Identity Provider (IdP) mapper component. A restricted administrator can abuse a misconfigured or specifically a Hardcoded Role mapper to assign high-privilege roles (e.g., realm-admin) to themselves or other users, bypassing security checks and gaining full cont...

Incorrect Privilege Assignment

Overview org.keycloak:keycloak-services is an open source identity and access management solution for modern applications and services. Affected versions of this package are vulnerable to Incorrect Privilege Assignment in the Identity Provider mapper process. An attacker can gain unauthorized...

PT-2026-53862

A flaw was found in Keycloak. A highly privileged user with manage-clients permission can exploit this vulnerability by injecting a hardcoded role mapper into any client. This action allows the user to bypass existing scope restrictions and inject the realm-admin role into generated tokens,...

PT-2026-53859

A flaw was found in the Identity Provider IdP mapper component of Keycloak, which is used to manage how user information from external services is mapped to Keycloak users. An administrator with limited permissions to manage identity providers can exploit this flaw by creating a "Hardcoded Role"...

CVE-2026-53064

A flaw was found in the Linux kernel's device-mapper dm-cache component. When dm-cache operates in passthrough mode, a race condition can occur during concurrent write operations to the same cached block. This can lead to a null-pointer dereference in the invalidatecomplete function, potentially...

CVE-2026-53063

A flaw was found in the Linux kernel's device-mapper dm cache component. Incomplete logic within the invalidateremove function, which handles write operations after cache invalidation, can lead to a system hang. This occurs because the function sets up remapping for write operations but fails to...

CVE-2026-53060

A flaw was found in the Linux kernel's device-mapper dm cache metadata. This memory leak vulnerability occurs when the dmcachemetadataabort function fails to acquire the root lock because the block manager is read-only, leading to the improper release of a temporary block manager. A local attacke...

CVE-2026-53062

A flaw was found in the Linux kernel's device-mapper dm cache policy, specifically within the smq module. In passthrough mode, the invalidatemapping operation lacks proper locking, allowing for concurrent access. This can lead to data races, resulting in data corruption or use-after-free issues,...

CVE-2026-53061

A flaw was found in the Linux kernel's device-mapper dm cache component. This vulnerability arises from an incorrect assumption that table reloads only occur after suspension, which is violated by Logical Volume Manager LVM table preloading. The dirty mapping check for passthrough mode, performed...
