In the Linux kernel, the following vulnerability has been resolved: tomoyo: fix UAF write bug in tomoyo_write_control() Since tomoyo_write_control() updates head->write_buf when write() of long lines is requested, we need to fetch head->write_buf after head->io_sem is held. Otherwise, concurrent write() requests can cause use-after-free-write and double-free problems. CREATE(Triage):(User=admin) CVE-2024-26622 (https://nvd.nist.gov/vuln/detail/CVE-2024-26622)
