Description

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.

Affected configurations

• linux linux kernel (>= 3.1 < 5.10.212) • linux linux kernel (>= 5.11 < 5.15.151) • linux linux kernel (>= 5.16 < 6.1.81) • linux linux kernel (>= 6.2 < 6.6.21) • linux linux kernel (>= 6.7 < 6.7.9) • linux linux kernel 6.8
