CVE-2023-54166

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> igc: Fix Kernel Panic during ndo_tx_timeout callback<br /> <br /> The Xeon validation group has been carrying out some loaded tests<br /> with various HW configurations, and they have seen some transmit<br /> queue time out happening during the test. This will cause the<br /> reset adapter function to be called by igc_tx_timeout().<br /> Similar race conditions may arise when the interface is being brought<br /> down and up in igc_reinit_locked(), an interrupt being generated, and<br /> igc_clean_tx_irq() being called to complete the TX.<br /> <br /> When the igc_tx_timeout() function is invoked, this patch will turn<br /> off all TX ring HW queues during igc_down() process. TX ring HW queues<br /> will be activated again during the igc_configure_tx_ring() process<br /> when performing the igc_up() procedure later.<br /> <br /> This patch also moved existing igc_disable_tx_ring_hw() to avoid using<br /> forward declaration.<br /> <br /> Kernel trace:<br /> [ 7678.747813] ------------[ cut here ]------------<br /> [ 7678.757914] NETDEV WATCHDOG: enp1s0 (igc): transmit queue 2 timed out<br /> [ 7678.770117] WARNING: CPU: 0 PID: 13 at net/sched/sch_generic.c:525 dev_watchdog+0x1ae/0x1f0<br /> [ 7678.784459] Modules linked in: xt_conntrack nft_chain_nat xt_MASQUERADE xt_addrtype nft_compat<br /> nf_tables nfnetlink br_netfilter bridge stp llc overlay dm_mod emrcha(PO) emriio(PO) rktpm(PO)<br /> cegbuf_mod(PO) patch_update(PO) se(PO) sgx_tgts(PO) mktme(PO) keylocker(PO) svtdx(PO) svfs_pci_hotplug(PO)<br /> vtd_mod(PO) davemem(PO) svmabort(PO) svindexio(PO) usbx2(PO) ehci_sched(PO) svheartbeat(PO) ioapic(PO)<br /> sv8259(PO) svintr(PO) lt(PO) pcierootport(PO) enginefw_mod(PO) ata(PO) smbus(PO) spiflash_cdf(PO) arden(PO)<br /> dsa_iax(PO) oobmsm_punit(PO) cpm(PO) svkdb(PO) ebg_pch(PO) pch(PO) sviotargets(PO) svbdf(PO) svmem(PO)<br /> svbios(PO) dram(PO) svtsc(PO) targets(PO) superio(PO) svkernel(PO) cswitch(PO) mcf(PO) pentiumIII_mod(PO)<br /> fs_svfs(PO) mdevdefdb(PO) svfs_os_services(O) ixgbe mdio mdio_devres libphy emeraldrapids_svdefs(PO)<br /> regsupport(O) libnvdimm nls_cp437 snd_hda_codec_realtek snd_hda_codec_generic ledtrig_audio snd_hda_intel<br /> snd_intel_dspcfg snd_hda_codec snd_hwdep x86_pkg_temp_thermal snd_hda_core snd_pcm snd_timer isst_if_mbox_pci<br /> [ 7678.784496] input_leds isst_if_mmio sg snd isst_if_common soundcore wmi button sad9(O) drm fuse backlight<br /> configfs efivarfs ip_tables x_tables vmd sdhci led_class rtl8150 r8152 hid_generic pegasus mmc_block usbhid<br /> mmc_core hid megaraid_sas ixgb igb i2c_algo_bit ice i40e hpsa scsi_transport_sas e1000e e1000 e100 ax88179_178a<br /> usbnet xhci_pci sd_mod xhci_hcd t10_pi crc32c_intel crc64_rocksoft igc crc64 crc_t10dif usbcore<br /> crct10dif_generic ptp crct10dif_common usb_common pps_core<br /> [ 7679.200403] RIP: 0010:dev_watchdog+0x1ae/0x1f0<br /> [ 7679.210201] Code: 28 e9 53 ff ff ff 4c 89 e7 c6 05 06 42 b9 00 01 e8 17 d1 fb ff 44 89 e9 4c<br /> 89 e6 48 c7 c7 40 ad fb 81 48 89 c2 e8 52 62 82 ff 0b e9 72 ff ff ff 65 8b 05 80 7d 7c 7e<br /> 89 c0 48 0f a3 05 0a c1<br /> [ 7679.245438] RSP: 0018:ffa00000001f7d90 EFLAGS: 00010282<br /> [ 7679.256021] RAX: 0000000000000000 RBX: ff11000109938440 RCX: 0000000000000000<br /> [ 7679.268710] RDX: ff11000361e26cd8 RSI: ff11000361e1b880 RDI: ff11000361e1b880<br /> [ 7679.281314] RBP: ffa00000001f7da8 R08: ff1100035f8fffe8 R09: 0000000000027ffb<br /> [ 7679.293840] R10: 0000000000001f0a R11: ff1100035f840000 R12: ff11000109938000<br /> [ 7679.306276] R13: 0000000000000002 R14: dead000000000122 R15: ffa00000001f7e18<br /> [ 7679.318648] FS: 0000000000000000(0000) GS:ff11000361e00000(0000) knlGS:0000000000000000<br /> [ 7679.332064] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033<br /> [ 7679.342757] CR2: 00007ffff7fca168 CR3: 000000013b08a006 CR4: 0000000000471ef8<br /> [ 7679.354984] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000<br /> [ 7679.367207] DR3: 0000000000000000 DR6: 00000000fffe07f0 DR7: 0000000000000400<br /> [ 7679.379370] PKRU: 55555554<br /> [ 7679.386446] Call Trace:<br /> [ 7679.393152] <br /> [ 7679.399363] ? __pfx_dev_watchdog+0x10/0x10<br /> [ 7679.407870] call_timer_fn+0x31/0x110<br /> [ 7679.415698] e<br /> ---truncated---
