Vulnerability from github – Published: 2024-06-08 15:31 – Updated: 2025-10-01 15:30In the Linux kernel, the following vulnerability has been resolved:
erofs: reliably distinguish block based and fscache mode
When erofs_kill_sb() is called in block dev based mode, s_bdev may not have been initialised yet, and if CONFIG_EROFS_FS_ONDEMAND is enabled, it will be mistaken for fscache mode, and then attempt to free an anon_dev that has never been allocated, triggering the following warning:

Vulnerability from github – Published: 2024-05-03 03:30 – Updated: 2024-05-03 03:30Fatek Automation FvDesigner FPJ File Parsing Uninitialized Pointer Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Fatek Automation FvDesigner. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of FPJ files. The issue results from the lack of proper initialization of a pointer prior to accessing it. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-18162.
