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: media: dvbdev: prevent the risk of out of memory access The dvbdev contains a static variable used to store dvb minors. The behavior of it depends if CONFIG_DVB_DYNAMIC_MINORS is set or not. When not set, dvb_register_device() won't check for boundaries, as it will rely that a previous call to dvb_register_adapter() would already be enforcing it. On a similar way, dvb_device_open() uses the assumption that the register functions already did the needed checks. This can be fragile if some device ends using different calls. This also generate warnings on static check analysers like Coverity. So, add explicit guards to prevent potential risk of OOM issues.

Vendor patch git.kernel.org →
Recommended fix High confidence

Kernel 4.19.324+, 5.4.286+, 5.10.230+, or 5.15.172+ depending on your current branch

  1. 1. Identify the currently running Linux kernel version using 'uname -r'
  2. 2. Determine which kernel branch (4.19, 5.4, 5.10, or 5.15) your system is running
  3. 3. Upgrade to a kernel version that includes the fix: 4.19.324 or later for 4.19.x, 5.4.286 or later for 5.4.x, 5.10.230 or later for 5.10.x, or 5.15.172 or later for 5.15.x
  4. 4. For Debian/Ubuntu: sudo apt-get update && sudo apt-get dist-upgrade, then reboot
  5. 5. For RHEL/CentOS: sudo yum update kernel, then reboot
  6. 6. For compiled-from-source kernels: download and compile the appropriate stable kernel source from kernel.org
  7. 7. Verify the fix is present by checking the dvbdev.c file in drivers/media/dvb-core/ for the added boundary checks
  8. 8. Reboot into the updated kernel and verify system stability
Caveat Kernel upgrades may require rebuilding out-of-tree kernel modules; ensure proprietary drivers (GPU, network, storage) are compatible with the new version before upgrading production systems
