 漏洞编号：[CVE-2025-38042](https://nvd.nist.gov/vuln/detail/CVE-2025-38042)
 漏洞归属组件：[kernel](https://gitee.com/src-openeuler/kernel)
 漏洞归属的版本：4.19.140,4.19.194,4.19.90,5.10.0,6.1.19,6.4.0,6.6.0
 CVSS V3.0分值：
  BaseScore：N/A None
  Vector：CVSS：3.0/
 漏洞简述：
  In the Linux kernel, the following vulnerability has been resolved:dmaengine: ti: k3-udma-glue: Drop skip_fdq argument from k3_udma_glue_reset_rx_chnThe user of k3_udma_glue_reset_rx_chn() e.g. ti_am65_cpsw_nuss canrun on multiple platforms having different DMA architectures.On some platforms there can be one FDQ for all flows in the RX channelwhile for others there is a separate FDQ for each flow in the RX channel.So far we have been relying on the skip_fdq argument ofk3_udma_glue_reset_rx_chn().Instead of relying on the user to provide this information, infer itbased on DMA architecture during k3_udma_glue_request_rx_chn() and save itin an internal flag  single_fdq . Use that flag atk3_udma_glue_reset_rx_chn() to deicide if the FDQ needsto be cleared for every flow or just for flow 0.Fixes the below issue on ti_am65_cpsw_nuss driver on AM62-SK.> ip link set eth1 down> ip link set eth0 down> ethtool -L eth0 rx 8> ip link set eth0 up> modprobe -r ti_am65_cpsw_nuss[  103.045726] ------------[ cut here ]------------[  103.050505] k3_knav_desc_pool size 512000 != avail 64000[  103.050703] WARNING: CPU: 1 PID: 450 at drivers/net/ethernet/ti/k3-cppi-desc-pool.c:33 k3_cppi_desc_pool_destroy+0xa0/0xa8 [k3_cppi_desc_pool][  103.068810] Modules linked in: ti_am65_cpsw_nuss(-) k3_cppi_desc_pool snd_soc_hdmi_codec crct10dif_ce snd_soc_simple_card snd_soc_simple_card_utils display_connector rtc_ti_k3 k3_j72xx_bandgap tidss drm_client_lib snd_soc_davinci_mcasp drm_dma_helper tps6598x phylink snd_soc_ti_udma rti_wdt drm_display_helper snd_soc_tlv320aic3x_i2c typec at24 phy_gmii_sel snd_soc_ti_edma snd_soc_tlv320aic3x sii902x snd_soc_ti_sdma sa2ul omap_mailbox drm_kms_helper authenc cfg80211 rfkill fuse drm drm_panel_orientation_quirks backlight ip_tables x_tables ipv6 [last unloaded: k3_cppi_desc_pool][  103.119950] CPU: 1 UID: 0 PID: 450 Comm: modprobe Not tainted 6.13.0-rc7-00001-g9c5e3435fa66 #1011[  103.119968] Hardware name: Texas Instruments AM625 SK (DT)[  103.119974] pstate: 80000005 (Nzcv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--)[  103.119983] pc : k3_cppi_desc_pool_destroy+0xa0/0xa8 [k3_cppi_desc_pool][  103.148007] lr : k3_cppi_desc_pool_destroy+0xa0/0xa8 [k3_cppi_desc_pool][  103.154709] sp : ffff8000826ebbc0[  103.158015] x29: ffff8000826ebbc0 x28: ffff0000090b6300 x27: 0000000000000000[  103.165145] x26: 0000000000000000 x25: 0000000000000000 x24: ffff0000019df6b0[  103.172271] x23: ffff0000019df6b8 x22: ffff0000019df410 x21: ffff8000826ebc88[  103.179397] x20: 000000000007d000 x19: ffff00000a3b3000 x18: 0000000000000000[  103.186522] x17: 0000000000000000 x16: 0000000000000000 x15: 000001e8c35e1cde[  103.193647] x14: 0000000000000396 x13: 000000000000035c x12: 0000000000000000[  103.200772] x11: 000000000000003a x10: 00000000000009c0 x9 : ffff8000826eba20[  103.207897] x8 : ffff0000090b6d20 x7 : ffff00007728c180 x6 : ffff00007728c100[  103.215022] x5 : 0000000000000001 x4 : ffff000000508a50 x3 : ffff7ffff6146000[  103.222147] x2 : 0000000000000000 x1 : e300b4173ee6b200 x0 : 0000000000000000[  103.229274] Call trace:[  103.231714]  k3_cppi_desc_pool_destroy+0xa0/0xa8 [k3_cppi_desc_pool] (P)[  103.238408]  am65_cpsw_nuss_free_rx_chns+0x28/0x4c [ti_am65_cpsw_nuss][  103.244942]  devm_action_release+0x14/0x20[  103.249040]  release_nodes+0x3c/0x68[  103.252610]  devres_release_all+0x8c/0xdc[  103.256614]  device_unbind_cleanup+0x18/0x60[  103.260876]  device_release_driver_internal+0xf8/0x178[  103.266004]  driver_detach+0x50/0x9c[  103.269571]  bus_remove_driver+0x6c/0xbc[  103.273485]  driver_unregister+0x30/0x60[  103.277401]  platform_driver_unregister+0x14/0x20[  103.282096]  am65_cpsw_nuss_driver_exit+0x18/0xff4 [ti_am65_cpsw_nuss][  103.288620]  __arm64_sys_delete_module+0x17c/0x25c[  103.293404]  invoke_syscall+0x44/0x100[  103.297149]  el0_svc_common.constprop.0+0xc0/0xe0[  103.301845]  do_el0_svc+0x1c/0x28[  103.305155]  el0_svc+0x28/0x98---truncated---
