CVE-2026-22693 1 Harfbuzz Project 1 Harfbuzz 2026-02-18 N/A 5.3 MEDIUM
HarfBuzz is a text shaping engine. Prior to version 12.3.0, a null pointer dereference vulnerability exists in the SubtableUnicodesCache::create function located in src/hb-ot-cmap-table.hh. The function fails to check if hb_malloc returns NULL before using placement new to construct an object at the returned pointer address. When hb_malloc fails to allocate memory (which can occur in low-memory conditions or when using custom allocators that simulate allocation failures), it returns NULL. The code then attempts to call the constructor on this null pointer using placement new syntax, resulting in undefined behavior and a Segmentation Fault. This issue has been patched in version 12.3.0.
CVE-2023-41633 1 Fossies 1 Catdoc 2026-02-18 N/A 5.5 MEDIUM
Catdoc v0.95 was discovered to contain a NULL pointer dereference via the component xls2csv at src/fileutil.c.
CVE-2025-20793 1 Mediatek 53 Mt2735, Mt2737, Mt6813 and 50 more 2026-02-17 N/A 6.5 MEDIUM
In Modem, there is a possible system crash due to incorrect error handling. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY01430930; Issue ID: MSV-4836.
CVE-2025-20750 1 Mediatek 26 Mt2735, Mt6833, Mt6833p and 23 more 2026-02-17 N/A 6.5 MEDIUM
In Modem, there is a possible system crash due to improper input validation. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY01661199; Issue ID: MSV-4296.
CVE-2025-20647 1 Mediatek 77 Mt2735, Mt2737, Mt6739 and 74 more 2026-02-17 N/A 6.5 MEDIUM
In Modem, there is a possible system crash due to a missing bounds check. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY00791311 / MOLY01067019; Issue ID: MSV-2721.
