CWE-125

Description

In the Linux kernel, the following vulnerability has been resolved: usb: typec: fix potential out of bounds in ucsi_ccg_update_set_new_cam_cmd() The "*cmd" variable can be controlled by the user via debugfs. That means "new_cam" can be as high as 255 while the size of the uc->updated[] array is UCSI_MAX_ALTMODES (30). The call tree is: ucsi_cmd() // val comes from simple_attr_write_xsigned() -> ucsi_send_command() -> ucsi_send_command_common() -> ucsi_run_command() // calls ucsi->ops->sync_control() -> ucsi_ccg_sync_control()

Affected configurations

• linux linux kernel (>= 5.6 < 5.10.230) • linux linux kernel (>= 5.11 < 5.15.172) • linux linux kernel (>= 5.16 < 6.1.117) • linux linux kernel (>= 6.2 < 6.6.61) • linux linux kernel (>= 6.7 < 6.11.8) • linux linux kernel 6.12
