CVE-2024-26622: Linux Kernel

High severity, CVSS 7.8. EPSS: 0.2% chance of exploitation in the next 30 days.

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 products

• Linux Linux Kernel: from 3.1, before 5.10.212 (fixed in 5.10.212); from 5.11, before 5.15.151 (fixed in 5.15.151); from 5.16, before 6.1.81 (fixed in 6.1.81); from 6.2, before 6.6.21 (fixed in 6.6.21); from 6.7, before 6.7.9 (fixed in 6.7.9); version 6.8 only
