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: nvkm: correctly calculate the available space of the GSP cmdq buffer r535_gsp_cmdq_push() waits for the available page in the GSP cmdq buffer when handling a large RPC request. When it sees at least one available page in the cmdq, it quits the waiting with the amount of free buffer pages in the queue. Unfortunately, it always takes the [write pointer, buf_size) as available buffer pages before rolling back and wrongly calculates the size of the data should be copied. Thus, it can overwrite the RPC request that GSP is currently reading, which causes GSP hang due to corrupted RPC request: [ 549.209389] ------------[ cut here ]------------ [ 549.214010] WARNING: CPU: 8 PID: 6314 at drivers/gpu/drm/nouveau/nvkm/subdev/gsp/r535.c:116 r535_gsp_msgq_wait+0xd0/0x190 [nvkm] [ 549.225678] Modules linked in: nvkm(E+) gsp_log(E) snd_seq_dummy(E) snd_hrtimer(E) snd_seq(E) snd_timer(E) snd_seq_device(E) snd(E) soundcore(E) rfkill(E) qrtr(E) vfat(E) fat(E) ipmi_ssif(E) amd_atl(E) intel_rapl_msr(E) intel_rapl_common(E) mlx5_ib(E) amd64_edac(E) edac_mce_amd(E) kvm_amd(E) ib_uverbs(E) kvm(E) ib_core(E) acpi_ipmi(E) ipmi_si(E) mxm_wmi(E) ipmi_devintf(E) rapl(E) i2c_piix4(E) wmi_bmof(E) joydev(E) ptdma(E) acpi_cpufreq(E) k10temp(E) pcspkr(E) ipmi_msghandler(E) xfs(E) libcrc32c(E) ast(E) i2c_algo_bit(E) crct10dif_pclmul(E) drm_shmem_helper(E) nvme_tcp(E) crc32_pclmul(E) ahci(E) drm_kms_helper(E) libahci(E) nvme_fabrics(E) crc32c_intel(E) nvme(E) cdc_ether(E) mlx5_core(E) nvme_core(E) usbnet(E) drm(E) libata(E) ccp(E) ghash_clmulni_intel(E) mii(E) t10_pi(E) mlxfw(E) sp5100_tco(E) psample(E) pci_hyperv_intf(E) wmi(E) dm_multipath(E) sunrpc(E) dm_mirror(E) dm_region_hash(E) dm_log(E) dm_mod(E) be2iscsi(E) bnx2i(E) cnic(E) uio(E) cxgb4i(E) cxgb4(E) tls(E) libcxgbi(E) libcxgb(E) qla4xxx(E) [ 549.225752] iscsi_boot_sysfs(E) iscsi_tcp(E) libiscsi_tcp(E) libiscsi(E) scsi_transport_iscsi(E) fuse(E) [last unloaded: gsp_log(E)] [ 549.326293] CPU: 8 PID: 6314 Comm: insmod Tainted: G E 6.9.0-rc6+ #1 [ 549.334039] Hardware name: ASRockRack 1U1G-MILAN/N/ROMED8-NL, BIOS L3.12E 09/06/2022 [ 549.341781] RIP: 0010:r535_gsp_msgq_wait+0xd0/0x190 [nvkm] [ 549.347343] Code: 08 00 00 89 da c1 e2 0c 48 8d ac 11 00 10 00 00 48 8b 0c 24 48 85 c9 74 1f c1 e0 0c 4c 8d 6d 30 83 e8 30 89 01 e9 68 ff ff ff <0f> 0b 49 c7 c5 92 ff ff ff e9 5a ff ff ff ba ff ff ff ff be c0 0c [ 549.366090] RSP: 0018:ffffacbccaaeb7d0 EFLAGS: 00010246 [ 549.371315] RAX: 0000000000000000 RBX: 0000000000000012 RCX: 0000000000923e28 [ 549.378451] RDX: 0000000000000000 RSI: 0000000055555554 RDI: ffffacbccaaeb730 [ 549.385590] RBP: 0000000000000001 R08: ffff8bd14d235f70 R09: ffff8bd14d235f70 [ 549.392721] R10: 0000000000000002 R11: ffff8bd14d233864 R12: 0000000000000020 [ 549.399854] R13: ffffacbccaaeb818 R14: 0000000000000020 R15: ffff8bb298c67000 [ 549.406988] FS: 00007f5179244740(0000) GS:ffff8bd14d200000(0000) knlGS:0000000000000000 [ 549.415076] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 549.420829] CR2: 00007fa844000010 CR3: 00000001567dc005 CR4: 0000000000770ef0 [ 549.427963] PKRU: 55555554 [ 549.430672] Call Trace: [ 549.433126] <TASK> [ 549.435233] ? __warn+0x7f/0x130 [ 549.438473] ? r535_gsp_msgq_wait+0xd0/0x190 [nvkm] [ 549.443426] ? report_bug+0x18a/0x1a0 [ 549.447098] ? handle_bug+0x3c/0x70 [ 549.450589] ? exc_invalid_op+0x14/0x70 [ 549.454430] ? asm_exc_invalid_op+0x16/0x20 [ 549.458619] ? r535_gsp_msgq_wait+0xd0/0x190 [nvkm] [ 549.463565] r535_gsp_msg_recv+0x46/0x230 [nvkm] [ 549.468257] r535_gsp_rpc_push+0x106/0x160 [nvkm] [ 549.473033] r535_gsp_rpc_rm_ctrl_push+0x40/0x130 [nvkm] [ 549.478422] nvidia_grid_init_vgpu_types+0xbc/0xe0 [nvkm] [ 549.483899] nvidia_grid_init+0xb1/0xd0 [nvkm] [ 549.488420] ? srso_alias_return_thunk+0x5/0xfbef5 [ 549.493213] nvkm_device_pci_probe+0x305/0x420 [nvkm] [ 549.498338] local_pci_probe+0x46/ ---truncated---

Recommended fix High confidence

Linux kernel >= 6.12.14 or >= 6.13.3

  1. Upgrade the Linux kernel to version 6.12.14 or later (if using the 6.12.x stable branch)
  2. Alternatively, upgrade to version 6.13.3 or later (if using the 6.13.x stable branch)
  3. Verify the kernel version after reboot using 'uname -r'
Caveat Kernel upgrades may require updating other system components; ensure driver compatibility with the new kernel version before upgrading production systems
