CVSS: 5.5EPSS: 0%CPEs: 4EXPL: 0CVE-2024-35911 – ice: fix memory corruption bug with suspend and rebuild
https://notcve.org/view.php?id=CVE-2024-35911
In the Linux kernel, the following vulnerability has been resolved: ice: fix memory corruption bug with suspend and rebuild The ice driver would previously panic after suspend. This is caused from the driver *only* calling the ice_vsi_free_q_vectors() function by itself, when it is suspending. Since commit b3e7b3a6ee92 ("ice: prevent NULL pointer deref during reload") the driver has zeroed out num_q_vectors, and only restored it in ice_vsi_cfg_def(). This further causes the ice_rebuild() function to allocate a zero length buffer, after which num_q_vectors is updated, and then the new value of num_q_vectors is used to index into the zero length buffer, which corrupts memory. The fix entails making sure all the code referencing num_q_vectors only does so after it has been reset via ice_vsi_cfg_def(). I didn't perform a full bisect, but I was able to test against 6.1.77 kernel and that ice driver works fine for suspend/resume with no panic, so sometime since then, this problem was introduced. Also clean up an un-needed init of a local variable in the function being modified.

CVSS: 5.8EPSS: 0%CPEs: 8EXPL: 0CVE-2024-35910 – tcp: properly terminate timers for kernel sockets
https://notcve.org/view.php?id=CVE-2024-35910
In the Linux kernel, the following vulnerability has been resolved: tcp: properly terminate timers for kernel sockets We had various syzbot reports about tcp timers firing after the corresponding netns has been dismantled. Fortunately Josef Bacik could trigger the issue more often, and could test a patch I wrote two years ago. When TCP sockets are closed, we call inet_csk_clear_xmit_timers() to 'stop' the timers. inet_csk_clear_xmit_timers() can be called from any context, including when socket lock is held. This is the reason it uses sk_stop_timer(), aka del_timer(). This means that ongoing timers might finish much later. For user sockets, this is fine because each running timer holds a reference on the socket, and the user socket holds a reference on the netns. For kernel sockets, we risk that the netns is freed before timer can complete, because kernel sockets do not hold reference on the netns. This patch adds inet_csk_clear_xmit_timers_sync() function that using sk_stop_timer_sync() to make sure all timers are terminated before the kernel socket is released. Modules using kernel sockets close them in their netns exit() handler. Also add sock_not_owned_by_me() helper to get LOCKDEP support : inet_csk_clear_xmit_timers_sync() must not be called while socket lock is held. It is very possible we can revert in the future commit 3a58f13a881e ("net: rds: acquire refcount on TCP sockets") which attempted to solve the issue in rds only. (net/smc/af_smc.c and net/mptcp/subflow.c have similar code) We probably can remove the check_net() tests from tcp_out_of_resources() and __tcp_close() in the future. En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: tcp: termina correctamente los temporizadores para los sockets del kernel. Recibimos varios informes de syzbot sobre los temporizadores tcp que se activan después de que se han desmantelado las redes correspondientes. Afortunadamente, Josef Bacik pudo provocar el problema con más frecuencia y pudo probar un parche que escribí hace dos años. Cuando los sockets TCP están cerrados, llamamos a inet_csk_clear_xmit_timers() para "detener" los temporizadores. • https://git.kernel.org/stable/c/8a68173691f036613e3d4e6bf8dc129d4a7bf383 https://git.kernel.org/stable/c/93f0133b9d589cc6e865f254ad9be3e9d8133f50 https://git.kernel.org/stable/c/44e62f5d35678686734afd47c6a421ad30772e7f https://git.kernel.org/stable/c/e3e27d2b446deb1f643758a0c4731f5c22492810 https://git.kernel.org/stable/c/2e43d8eba6edd1cf05a3a20fdd77688fa7ec16a4 https://git.kernel.org/stable/c/91b243de910a9ac8476d40238ab3dbfeedd5b7de https://git.kernel.org/stable/c/c1ae4d1e76eacddaacb958b67cd942082f800c87 https://git.kernel.org/stable/c/899265c1389fe022802aae73dbf13ee08 •

Fix alignment by forcing all accesses to be 32bit on 64bit platforms. En el kernel de Linux se ha resuelto la siguiente vulnerabilidad: net: wwan: t7xx: Accesos divididos de 64 bits para solucionar problemas de alineación Algunos de los registros están alineados en un límite de 32 bits, provocando fallos de alineación en plataformas de 64 bits. No se puede manejar la solicitud de paginación del kernel en la dirección virtual ffffffc084a1d004 Información de cancelación de memoria: ESR = 0x0000000096000061 EC = 0x25: DABT (EL actual), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 FSC = 0x21: alineación falla Información de cancelación de datos: ISV = 0, ISS = 0x00000061, ISS2 = 0x00000000 CM = 0, WnR = 1, TnD = 0, TagAccess = 0 GCS = 0, Overlay = 0, DirtyBit = 0, Xs = 0 tabla de intercambio: 4k páginas, VA de 39 bits, pgdp=0000000046ad6000 [ffffffc084a1d004] pgd=100000013ffff003, p4d=100000013ffff003, pud=100000013ffff003, pmd=0068000020a00711 Error interno: Vaya: 0000000096000061 [#1] Módulos SMP vinculados en: mtk_t7xx(+) qcserial pppoe ppp_async opción nft_fib_inet nf_flow_table_inet mt7921u(O) mt7921s(O) mt7921e(O) mt7921_common(O) iwlmvm(O) iwldvm(O) usb_wwan rndis_host qmi_wwan pppox ppp_generic nft_reject_ipv6 nft_reject_ipv4 n ft_reject_inet nft_reject nft_redir nft_quota nft_numgen nft_nat nft_masq nft_log nft_limit nft_hash nft_flow_offload nft_fib_ipv6 nft_fib_ipv4 nft_fib nft_ct nft_chain_nat nf_tables nf_nat nf_flow_table nf_conntrack mt7996e(O) mt792x_usb(O) mt792x_lib(O) mt7915e(O) mt76_usb(O) mt76_sdio(O) mt76_connac_lib(O) mt76(O) mac80211(O) O) huawei_cdc_ncm cfg80211(O) cdc_ncm cdc_ether wwan usbserial usbnet slhc sfp rtc_pcf8563 nfnetlink nf_reject_ipv6 nf_reject_ipv4 nf_log_syslog nf_defrag_ipv6 nf_defrag_ipv4 mt6577_auxadc mdio_i2c libcrc32c compat(O) cdc_wdm c_acm at24 crypto_safexcel pwm_fan i2c_gpio i2c_smbus industrialio i2c_algo_bit i2c_mux_reg i2c_mux_pca954x i2c_mux_pca9541 i2c_mux_gpio i2c_mux dummy oid_registry tun sha512_arm64 sha1_ce sha1_generic seqiv md5 des_generic libdes cbc authencesn authenc leds_gpio xhci_plat_hcd xhci_pci xhci_mtk_hcd xhci_hcd nvme nvme_core gpio_button_hotplug(O) dm_mirror dm_region_hash dm_log dm_crypt dm_mod dax usbcore usb_common ptp aquantia pps_core mii tpm encrypted_keys CPU confiable: 3 PID: 5266 Comm: kworker/u9:1 ted: GO 6.6.22 #0 Nombre del hardware: Bananapi BPI -R4 (DT) Cola de trabajo: md_hk_wq t7xx_fsm_uninit [mtk_t7xx] pstate: 804000c5 (Nzcv daIF +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc: t7xx_cldma_hw_set_start_addr+0x1c/0x3c [mtk_t7xx] lr: _cldma_start+0xac/0x13c [mtk_t7xx] sp: ffffffc085d63d30 x29: ffffffc085d63d30 x28: 0000000000000000 x27: 00000000000000000 x26: 0000000000000000 x25: ffffff80c804f2c 0 x24: ffffff80ca196c05 x23: 0000000000000000 x22: ffffff80c814b9b8 x21: ffffff80c814b128 x20: 00000000000000001 x19: ffffff80c814b080 x18: 00000000014 x17: 0000000055c9806b x16: 000000007c5296d0 x15: 000000000f6bca68 x14: 00000000dbdbdce4 x13: 000000001aeaf72a x12: 0000000000000001 x11: 00000000000000000 x10: 0000000000000000 x9: 000 0000000000000 x8: ffffff80ca1ef6b4 x7: ffffff80c814b818 x6: 0000000000000018 x5: 0000000000000870 x4: 0000000000000000 x3: 0000000000000000 0 x2: 000000010a947000 x1: ffffffc084a1d004 x0: ffffffc084a1d004 Rastreo de llamadas: t7xx_cldma_hw_set_start_addr +0x1c/0x3c [mtk_t7xx] t7xx_fsm_uninit+0x578/0x5ec [mtk_t7xx] Process_one_work+0x154/0x2a0 Workers_thread+0x2ac/0x488 kthread+0xe0/0xec ret_from_fork+0x10/0x20 Código: f9400800 9 1001000 8b214001 d50332bf (f9000022) ---[ final de seguimiento 0000000000000000 ]--- La inclusión de io-64-nonatomic-lo-hi.h indica que todos los accesos de 64 bits pueden ser reemplazados por pares de accesos no atómicos de 32 bits.
