[PATCH openEuler-1.0-LTS] tomoyo: fix UAF write bug in tomoyo_write_control()
by felix 15 Mar '24

From: Tetsuo Handa <penguin-kernel(a)I-love.SAKURA.ne.jp> stable inclusion from stable-v5.10.212 commit a23ac1788e2c828c097119e9a3178f0b7e503fee category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/I95LPF CVE: CVE-2024-26622 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- commit 2f03fc340cac9ea1dc63cbf8c93dd2eb0f227815 upstream. 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.
