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.

In the Linux kernel, the following vulnerability has been resolved: drm/v3d: Disable interrupts before resetting the GPU Currently, an interrupt can be triggered during a GPU reset, which can lead to GPU hangs and NULL pointer dereference in an interrupt context as shown in the following trace: [ 314.035040] Unable to handle kernel NULL pointer dereference at virtual address 00000000000000c0 [ 314.043822] Mem abort info: [ 314.046606] ESR = 0x0000000096000005 [ 314.050347] EC = 0x25: DABT (current EL), IL = 32 bits [ 314.055651] SET = 0, FnV = 0 [ 314.058695] EA = 0, S1PTW = 0 [ 314.061826] FSC = 0x05: level 1 translation fault [ 314.066694] Data abort info: [ 314.069564] ISV = 0, ISS = 0x00000005, ISS2 = 0x00000000 [ 314.075039] CM = 0, WnR = 0, TnD = 0, TagAccess = 0 [ 314.080080] GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0 [ 314.085382] user pgtable: 4k pages, 39-bit VAs, pgdp=0000000102728000 [ 314.091814] [00000000000000c0] pgd=0000000000000000, p4d=0000000000000000, pud=0000000000000000 [ 314.100511] Internal error: Oops: 0000000096000005 [#1] PREEMPT SMP [ 314.106770] Modules linked in: v3d i2c_brcmstb vc4 snd_soc_hdmi_codec gpu_sched drm_shmem_helper drm_display_helper cec drm_dma_helper drm_kms_helper drm drm_panel_orientation_quirks snd_soc_core snd_compress snd_pcm_dmaengine snd_pcm snd_timer snd backlight [ 314.129654] CPU: 0 UID: 0 PID: 0 Comm: swapper/0 Not tainted 6.12.25+rpt-rpi-v8 #1 Debian 1:6.12.25-1+rpt1 [ 314.139388] Hardware name: Raspberry Pi 4 Model B Rev 1.4 (DT) [ 314.145211] pstate: 600000c5 (nZCv daIF -PAN -UAO -TCO -DIT -SSBS BTYPE=--) [ 314.152165] pc : v3d_irq+0xec/0x2e0 [v3d] [ 314.156187] lr : v3d_irq+0xe0/0x2e0 [v3d] [ 314.160198] sp : ffffffc080003ea0 [ 314.163502] x29: ffffffc080003ea0 x28: ffffffec1f184980 x27: 021202b000000000 [ 314.170633] x26: ffffffec1f17f630 x25: ffffff8101372000 x24: ffffffec1f17d9f0 [ 314.177764] x23: 000000000000002a x22: 000000000000002a x21: ffffff8103252000 [ 314.184895] x20: 0000000000000001 x19: 00000000deadbeef x18: 0000000000000000 [ 314.192026] x17: ffffff94e51d2000 x16: ffffffec1dac3cb0 x15: c306000000000000 [ 314.199156] x14: 0000000000000000 x13: b2fc982e03cc5168 x12: 0000000000000001 [ 314.206286] x11: ffffff8103f8bcc0 x10: ffffffec1f196868 x9 : ffffffec1dac3874 [ 314.213416] x8 : 0000000000000000 x7 : 0000000000042a3a x6 : ffffff810017a180 [ 314.220547] x5 : ffffffec1ebad400 x4 : ffffffec1ebad320 x3 : 00000000000bebeb [ 314.227677] x2 : 0000000000000000 x1 : 0000000000000000 x0 : 0000000000000000 [ 314.234807] Call trace: [ 314.237243] v3d_irq+0xec/0x2e0 [v3d] [ 314.240906] __handle_irq_event_percpu+0x58/0x218 [ 314.245609] handle_irq_event+0x54/0xb8 [ 314.249439] handle_fasteoi_irq+0xac/0x240 [ 314.253527] handle_irq_desc+0x48/0x68 [ 314.257269] generic_handle_domain_irq+0x24/0x38 [ 314.261879] gic_handle_irq+0x48/0xd8 [ 314.265533] call_on_irq_stack+0x24/0x58 [ 314.269448] do_interrupt_handler+0x88/0x98 [ 314.273624] el1_interrupt+0x34/0x68 [ 314.277193] el1h_64_irq_handler+0x18/0x28 [ 314.281281] el1h_64_irq+0x64/0x68 [ 314.284673] default_idle_call+0x3c/0x168 [ 314.288675] do_idle+0x1fc/0x230 [ 314.291895] cpu_startup_entry+0x3c/0x50 [ 314.295810] rest_init+0xe4/0xf0 [ 314.299030] start_kernel+0x5e8/0x790 [ 314.302684] __primary_switched+0x80/0x90 [ 314.306691] Code: 940029eb 360ffc13 f9442ea0 52800001 (f9406017) [ 314.312775] ---[ end trace 0000000000000000 ]--- [ 314.317384] Kernel panic - not syncing: Oops: Fatal exception in interrupt [ 314.324249] SMP: stopping secondary CPUs [ 314.328167] Kernel Offset: 0x2b9da00000 from 0xffffffc080000000 [ 314.334076] PHYS_OFFSET: 0x0 [ 314.336946] CPU features: 0x08,00002013,c0200000,0200421b [ 314.342337] Memory Limit: none [ 314.345382] ---[ end Kernel panic - not syncing: Oops: Fatal exception in interrupt ]--- Before resetting the G ---truncated---

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-476

The code follows a pointer that is null, crashing the process. An attacker who can reliably trigger it turns the crash into a denial of service. The fix is checking for null before use and handling the failure path gracefully.

General guidance for the null pointer dereference class — the official description and references above are authoritative for this specific CVE. Want a bespoke review and a reviewed fix? Ask our team →

Upgrade available Upgrade to 5.4.296 / 5.10.240 / 5.15.187 or later
Fixed in 5.4.2965.10.2405.15.187
Vendor patch git.kernel.org →
Recommended fix High confidence

Upgrade to Linux kernel >= 5.4.296 (for 5.4.x branch), >= 5.10.240 (for 5.10.x branch), >= 5.15.187 (for 5.15.x branch), or >= 6.1.144 (for 6.1.x or later branch)

  1. Identify the current kernel version using `uname -r` and `dpkg -l | grep linux-image`
  2. For Debian 11 (bullseye), check if a newer kernel with the fix is available: `apt update && apt-cache policy linux-image-*`
  3. If a fixed kernel is available in Debian repos, install it: `apt install linux-image-<version>`
  4. If no fixed kernel is available in Debian repos, consider using upstream kernel packages from https://kernel.ubuntu.com/ or rebuilding with the patch from commit 226862f50a7a88e4e4de9abbf36c64d19acd6fd0
  5. Reboot the system to load the fixed kernel: `sudo reboot`
  6. Verify the fix is applied by checking `dmesg | grep -i v3d` for any errors and confirm the kernel version is >= 5.4.296, >= 5.10.240, >= 5.15.187, or >= 6.1.144 as appropriate
Caveat Kernel upgrades carry minimal risk but may introduce regressions; test in staging if possible. On Raspberry Pi devices using the v3d GPU driver, ensure peripheral firmware is compatible with the new kernel.
