CVE-2026-93198
Description détaillée
In the Linux kernel, the following vulnerability has been resolved: dm-pcache: validate the persisted dirty_tail chain at load The writeback worker follows the persisted dirty_tail chain, which is decoded from the cache device independently of the key_tail chain that cache_replay() walks and bounds. A crafted image, whose on-media fields are authenticated only by a crc32c with a fixed seed, can aim dirty_tail at a chain of last ksets that never terminates, so cache_writeback_fn() re-arms itself with no delay forever. Walk the dirty_tail chain once at load with the same hop cap cache_replay() uses and fail the table load with -EIO if it does not reach an end within n_segs hops.

CVE-2026-92992
A security vulnerability has been detected in Dromara mayfly-go up to 1.11.5. The affected element is an unknown function of the file server/internal/ai/api/ai.go of the component AI Assistant. The manipulation leads to missing authorization. Remote exploitation of the attack is possible. The exploit has been disclosed publicly and may be used. The identifier of the patch is 74bcb926eb4f5f94e7681144d7bf2168a0ec7cde. Applying a patch is the recommended action to fix this issue. The whitelist bypass is one-token wide. Any compound command containing curl, wget or sed auto-runs without approval; approval is granted by the same session user (self-approval). This issue got fixed with a silent patch.
CVE-2026-92230
Apache Karaf's XmlUtils cached XML parser/transformer factories in static ThreadLocal fields on long-lived container threads. Because a ThreadLocal value outlives the OSGi bundle that created it, repeated bundle or feature install, update, or refresh operations can leave successive bundle ClassLoader's pinned in memory and unreachable for garbage collection, leading to unbounded Metaspace growth and eventual denial of service of the Karaf instance.
CVE-2026-90997
A flaw was found in Keycloak. When deployed in stateless mode with MySQL or MariaDB, a mismatch in row-count semantics between the database driver and Keycloak's application logic allows an attacker to bypass replay protection. This vulnerability enables an attacker who intercepts single-use security artifacts, such as JWT client assertions, DPoP proofs, or one-time password (TOTP) codes, to replay them. Successful exploitation grants unauthorized access to the token endpoint or login flow.
