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 · unedited
In the Linux kernel, the following vulnerability has been resolved: fs/9p: only translate RWX permissions for plain 9P2000 Garbage in plain 9P2000's perm bits is allowed through, which causes it to be able to set (among others) the suid bit. This was presumably not the intent since the unix extended bits are handled explicitly and conditionally on .u.

Recommended fix High confidence

Linux kernel 4.19.314, 5.4.276, 5.10.217, or 5.15.159 (or any later stable version)

  1. Identify the current kernel version using `uname -r`
  2. Determine which major kernel branch you are running (e.g., 4.19, 5.4, 5.10, 5.15)
  3. Upgrade the Linux kernel to a fixed version: 4.19.314 or higher, 5.4.276 or higher, 5.10.217 or higher, or 5.15.159 or higher
  4. Update the kernel package using your distribution's package manager (e.g., apt-get update && apt-get upgrade for Debian/Ubuntu, yum update for RHEL/CentOS)
  5. Reboot the system to load the patched kernel
  6. Verify the fix by running `uname -r` to confirm the new kernel version and ensure it meets the minimum fixed version for your branch
Caveat Kernel upgrade requires system reboot and may have compatibility implications with existing system tools or modules
