Vulnerability from github – Published: 2024-12-27 15:31 – Updated: 2025-11-03 21:31

Details

In the Linux kernel, the following vulnerability has been resolved:

unicode: Fix utf8_load() error path

utf8_load() requests the symbol "utf8_data_table" and then checks if the requested UTF-8 version is supported. If it's unsupported, it tries to put the data table using symbol_put(). If an unsupported version is requested, symbol_put() fails like this:

kernel BUG at kernel/module/main.c:786! RIP: 0010:__symbol_put+0x93/0xb0 Call Trace: ? __die_body.cold+0x19/0x27 ? die+0x2e/0x50 ? do_trap+0xca/0x110 ? do_error_trap+0x65/0x80 ? __symbol_put+0x93/0xb0 ? exc_invalid_op+0x51/0x70 ? __symbol_put+0x93/0xb0 ? asm_exc_invalid_op+0x1a/0x20 ? __pfx_cmp_name+0x10/0x10 ? __symbol_put+0x93/0xb0 ? __symbol_put+0x62/0xb0 utf8_load+0xf8/0x150

That happens because symbol_put() expects the unique string that identify the symbol, instead of a pointer to the loaded symbol. Fix that by using such string.

Severity

5.5 (Medium)

If it\u0027s unsupported, it tries to\nput the data table using symbol_put(). If an unsupported version is\nrequested, symbol_put() fails like this:\n\n kernel BUG at kernel/module/main.c:786!\n RIP: 0010:__symbol_put+0x93/0xb0\n Call Trace:\n  \u003cTASK\u003e\n  ? __die_body.cold+0x19/0x27\n  ? die+0x2e/0x50\n  ? do_trap+0xca/0x110\n  ? do_error_trap+0x65/0x80\n  ? __symbol_put+0x93/0xb0\n  ? exc_invalid_op+0x51/0x70\n  ? __symbol_put+0x93/0xb0\n  ? asm_exc_invalid_op+0x1a/0x20\n  ? __pfx_cmp_name+0x10/0x10\n  ? __symbol_put+0x93/0xb0\n  ? __symbol_put+0x62/0xb0\n  utf8_load+0xf8/0x150\n\nThat happens because symbol_put() expects the unique string that\nidentify the symbol, instead of a pointer to the loaded symbol. Fix that\nby using such string."

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
