CVE-2026-46044
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIn the Linux kernel, the following vulnerability has been resolved: ipmi:ssif: Clean up kthread on errors If an error occurs after the ssif kthread is created, but before the main IPMI code starts the ssif interface, the ssif kthread will not be stopped. So make sure the kthread is stopped on an error condition if it is running.

Linux Kernel 5.10.258, 5.15.209, 6.18.27, or 7.0.4 (depending on your branch)
- Identify the currently running Linux kernel version using `uname -r`
- Determine which kernel branch your version belongs to (3.19-5.10.x, 5.11-5.15.x, 5.16-6.18.x, or 6.19-7.0.x)
- Upgrade to a kernel version >= 5.10.258 if on the 5.10 branch, >= 5.15.209 if on the 5.15 branch, >= 6.18.27 if on the 6.18 branch, or >= 7.0.4 if on the 7.0 branch
- Use your distribution's package manager to install the updated kernel (e.g., `apt update && apt upgrade` for Debian/Ubuntu, `yum update` for RHEL/CentOS, or `pacman -Syu` for Arch)
- Reboot the system to load the new kernel
