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: drm/msm/dpu: cleanup FB if dpu_format_populate_layout fails If the dpu_format_populate_layout() fails, then FB is prepared, but not cleaned up. This ends up leaking the pin_count on the GEM object and causes a splat during DRM file closure: msm_obj->pin_count WARNING: CPU: 2 PID: 569 at drivers/gpu/drm/msm/msm_gem.c:121 update_lru_locked+0xc4/0xcc [...] Call trace: update_lru_locked+0xc4/0xcc put_pages+0xac/0x100 msm_gem_free_object+0x138/0x180 drm_gem_object_free+0x1c/0x30 drm_gem_object_handle_put_unlocked+0x108/0x10c drm_gem_object_release_handle+0x58/0x70 idr_for_each+0x68/0xec drm_gem_release+0x28/0x40 drm_file_free+0x174/0x234 drm_release+0xb0/0x160 __fput+0xc0/0x2c8 __fput_sync+0x50/0x5c __arm64_sys_close+0x38/0x7c invoke_syscall+0x48/0x118 el0_svc_common.constprop.0+0x40/0xe0 do_el0_svc+0x1c/0x28 el0_svc+0x4c/0x120 el0t_64_sync_handler+0x100/0x12c el0t_64_sync+0x190/0x194 irq event stamp: 129818 hardirqs last enabled at (129817): [<ffffa5f6d953fcc0>] console_unlock+0x118/0x124 hardirqs last disabled at (129818): [<ffffa5f6da7dcf04>] el1_dbg+0x24/0x8c softirqs last enabled at (129808): [<ffffa5f6d94afc18>] handle_softirqs+0x4c8/0x4e8 softirqs last disabled at (129785): [<ffffa5f6d94105e4>] __do_softirq+0x14/0x20 Patchwork: https://patchwork.freedesktop.org/patch/600714/

Upgrade available Upgrade to 5.15.166 / 6.1.107 / 6.6.48 or later
Fixed in 5.15.1666.1.1076.6.48
Vendor patch git.kernel.org →
Recommended fix High confidence

Upgrade to kernel version 5.15.166, 6.1.107, 6.6.48, or 6.10.7 depending on your current branch (5.15.x, 6.1.x, 6.2-6.5.x, or 6.7-6.9.x)

  1. Identify the currently running kernel version using `uname -r`
  2. Determine which version range your current kernel falls into (>= 4.19, < 5.15.166 / >= 5.16, < 6.1.107 / >= 6.2, < 6.6.48 / >= 6.7, < 6.10.7)
  3. Upgrade the Linux kernel to the first fixed version in your branch: 5.15.166, 6.1.107, 6.6.48, or 6.10.7 respectively
  4. Update boot loader configuration if necessary (e.g., update-grub for GRUB)
  5. Reboot the system into the new kernel
  6. Verify the fix is applied by checking `dmesg` for any related warnings during boot and DRM operations
Caveat Kernel upgrades may require matching system libraries and drivers; ensure compatibility with userspace components before rebooting
