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: scsi: core: ufs: Fix a hang in the error handler ufshcd_err_handling_prepare() calls ufshcd_rpm_get_sync(). The latter function can only succeed if UFSHCD_EH_IN_PROGRESS is not set because resuming involves submitting a SCSI command and ufshcd_queuecommand() returns SCSI_MLQUEUE_HOST_BUSY if UFSHCD_EH_IN_PROGRESS is set. Fix this hang by setting UFSHCD_EH_IN_PROGRESS after ufshcd_rpm_get_sync() has been called instead of before.

Recommended fix High confidence

Linux Kernel 5.15.186 / 6.1.142 / 6.6.94 / 6.12.34 (or Debian 12 with kernel 6.12.34+)

  1. Identify the current running kernel version with `uname -r`
  2. For Debian 11 (Bullseye), upgrade the kernel package to a version >= 6.12.34 (or >= 6.6.94 if staying on 6.x, >= 6.1.142 if staying on 6.1.x, or >= 5.15.186 if staying on 5.15.x)
  3. Update package lists: `apt update`
  4. Install the new kernel: `apt install linux-image-<version>`
  5. Reboot the system to load the fixed kernel
Caveat Kernel upgrades may require system reboot and could have minor driver/module compatibility changes; ensure backup before upgrading
