CVE-2026-857696.5 MED—
———A flaw was found in libtpms, a library that provides software TPM 2.0 emulation. When restoring TPM 2.0 state (for example during a virtual machine's power-on or state/migration restore), a malformed state blob can supply an oversized skip-block length that is not validated against the remaining size of the input buffer. This can drive an internal size counter negative, which bypasses a subsequent bounds check due to an unsafe signed-to-unsigned conversion, causing the parser to read memory outside the bounds of the heap buffer holding the state data. Successful exploitation can crash the process hosting libtpms (such as swtpm), resulting in a denial of service of the emulated TPM device and the virtual machine that depends on it. No data corruption or information disclosure was confirmed.18hCVE-2026-166605.3 MED—
———IBM Db2 Mirror for i 7.4, 7.5, and 7.6 could allow a remote attacker to cause a denial of service due to an out-of-bounds read.20hCVE-2026-856985.5 MED—
———Turso through 0.8.0-pre.8 contains an out-of-bounds read vulnerability in the table-leaf page reader that uses an attacker-controlled cell-count field without bounds validation. Attackers can craft a malicious database file with a modified cell count value to trigger an index-out-of-bounds panic when querying, causing denial of service in any application that opens untrusted database files.22hCVE-2026-855225.3 MED—
———A vulnerability was detected in valkey-io valkey up to 9.5.4/9.1.0. Affected by this vulnerability is the function createSlotImportJob of the file src/cluster_migrateslots.c of the component Slot Migration. The manipulation of the argument job_name results in out-of-bounds read. The attack can be executed remotely. The exploit is now public and may be used. Upgrading to version 9.0.5 and 9.1.1 addresses this issue. The patch is identified as f4dc3ca09eb650c2fe14060090a41c524eca803f. Upgrading the affected component is advised.21hCVE-2026-855057.5 ALT—
