CVE-2026-92824

MEDIUM6.2

Published 2026-10-21 · Source secalert@redhat.com

Description

A flaw was found in libmodulemd. In the module stream v2 rpm-map emission path, an inner loop incorrectly uses the count of digest algorithms as its bound instead of the number of checksums in the current digest table. Crafted modulemd v2 metadata with multiple digest types can trigger an out-of-bounds read during YAML serialization, typically causing a crash and resulting in a denial of service.

CVE-2026-92823
A flaw was found in libmodulemd. In builds with rpmio support enabled, compressed modulemd YAML is decompressed through a custom read handler that does not enforce a cumulative decompressed-size limit before parsing. An attacker who can supply a highly compressible compressed YAML file can cause excessive CPU and memory consumption, resulting in a denial of service.

CVE-2026-92822
A flaw was found in libmodulemd. When parsing module metadata, the xmd field is converted into nested GVariant values through recursive YAML mapping and sequence helpers without a recursion-depth or node-count limit. An attacker who can supply crafted modulemd YAML with deeply nested xmd content can cause stack exhaustion or excessive resource consumption, resulting in a denial of service.

CVE-2026-113743
A weakness has been identified in Tenstorrent tt-metal up to 0.80.0. The affected element is the function load_hf_state_dict_filtered of the file models/tt_transformers/tt/load_checkpoints.py. This manipulation of the argument weight_map causes path traversal. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks. Upgrading to version 0.81.0-dev20261016 is sufficient to fix this issue. Patch name: 4851ccf347f6903c3d819eed60705600386e52c3. It is suggested to upgrade the affected component.

CVE-2026-114118
Vyper 0.3.4 through 0.5.0b1 computes the remaining blueprint size in create_from_blueprint by uint256 subtraction without first checking that code_offset is below the blueprint's code size, so a huge offset wraps to a small positive value. An attacker controlling code_offset can make a factory deploy contracts with no runtime code, potentially trapping ETH and tokens.
