CVE-2026-85769

CVE-2026-85769 Heap out-of-bounds read in libtpms TPM 2.0 volatile-state deserialization. An unbounded optional-block skip in blockskipread advances the unmarshal cursor by an attacker-controlled 16-bit length and drives the signed remaining-size counter negative. Every downstream bounds check th...

DEBIAN-CVE-2026-90114

In the Linux kernel, the following vulnerability has been resolved: net: bridge: Reject descending VLAN tunnel ranges A pair of descending VLAN and tunnel IDs can pass the tunnel range span check. The VLAN subtraction produces a negative int, which is converted to unsigned when compared with the...

CVE-2026-89612

In the Linux kernel, the following vulnerability has been resolved: ntfs: reject invalid MFT LCNs from boot sector The NTFS boot sector stores the MFT and MFTMirr locations as unsigned 64-bit LCNs, but parsentfsbootsector decoded them into an s64. A crafted high-bit value could therefore become...

AZL-99918 CVE-2026-85769 affecting package libtpms for versions less than 0.9.6-9

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 si...
