  "description": "In the Linux kernel, the following vulnerability has been resolved:  coresight: ETR: Fix ETR buffer use-after-free issue  When ETR is enabled as CS_MODE_SYSFS, if the buffer size is changed and enabled again, currently sysfs_buf will point to the newly allocated memory(buf_new) and free the old memory(buf_old). But the etr_buf that is being used by the ETR remains pointed to buf_old, not updated to buf_new. In this case, it will result in a memory use-after-free issue.  Fix this by checking ETR\u0027s mode before updating and releasing buf_old, if the mode is CS_MODE_SYSFS, then skip updating and releasing it.",
