CVE-2024-57913: usb: gadget: f_fs: Remove WARN_ON in functionfs_bind

Noroxi assessment

Priority: Monitor (action score 18/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.18% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: Linux Linux 19fc1c83454ca9d5699e39633ec79ce26355251c, 3e4d32cc145955d5c56c5498a3ff057e4aafa9d1, 82f60f3600aecd9ffcd0fbc4e193694511c85b47; azl3 kernel 6.6.64.2-9 on Azure Linux 3.0 6.6.78.1-3; cbl2 kernel 5.15.176.3-3 on CBL Mariner 2.0 5.15.180.1-1.

Low priority for now. Upgrade to Linux Linux 19fc1c83454ca9d5699e39633ec79ce26355251c, 3e4d32cc145955d5c56c5498a3ff057e4aafa9d1, 82f60f3600aecd9ffcd0fbc4e193694511c85b47; azl3 kernel 6.6.64.2-9 on Azure Linux 3.0 6.6.78.1-3; cbl2 kernel 5.15.176.3-3 on CBL Mariner 2.0 5.15.180.1-1 or later.

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: f_fs: Remove WARN_ON in functionfs_bind This commit addresses an issue related to below kernel panic where panic_on_warn is enabled. It is caused by the unnecessary use of WARN_ON in functionsfs_bind, which easily leads to the following scenarios. 1.adb_write in adbd 2. UDC write via configfs ================= ===================== ->usb_ffs_open_thread() ->UDC write ->open_functionfs() ->configfs_write_iter() ->adb_open() ->gadget_dev_desc_UDC_store() ->adb_write() ->usb_gadget_register_driver_owner ->driver_register() ->StartMonitor() ->bus_add_driver() ->adb_read() ->gadget_bind_driver() <times-out without BIND event> ->configfs_composite_bind() ->usb_add_function() ->open_functionfs() ->ffs_func_bind() ->adb_open() ->functionfs_bind() <ffs->state !=FFS_ACTIVE> The adb_open, adb_read, and adb_write operations are invoked from the daemon, but trying to bind the function is a process that is invoked by UDC write through configfs, which opens up the possibility of a race condition between the two paths. In this race scenario, the kernel panic occurs due to the WARN_ON from functionfs_bind when panic_on_warn is enabled. This commit fixes the kernel panic by removing the unnecessary WARN_ON.
