From: Zhengchao Shao <shaozhengchao(a)huawei.com> stable inclusion from stable-v4.19.293 commit da4cbaa75ed088b6d70db77b9103a27e2359e243 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID0RFJ CVE: CVE-2023-53500 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 53223f2ed1ef5c90dad814daaaefea4e68a933c8 ] When the xfrm device is set to the qdisc of the sfb type, the cb field of the sent skb may be modified during enqueuing. Then, slab-use-after-free may occur when the xfrm device sends IPv6 packets. The stack information is as follows: BUG: KASAN: slab-use-after-free in decode_session6+0x103f/0x1890 Read of size 1 at addr ffff8881111458ef by task swapper/3/0 CPU: 3 PID: 0 Comm: swapper/3 Not tainted 6.4.0-next-20230707 #409 Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.14.0-1.fc33 04/01/2014 Call Trace: <IRQ> dump_stack_lvl+0xd9/0x150 print_address_description.constprop.0+0x2c/0x3c0 kasan_report+0x11d/0x130 decode_session6+0x103f/0x1890 __xfrm_decode_session+0x54/0xb0 xfrmi_xmit+0x173/0x1ca0 dev_hard_start_xmit+0x187/0x700 sch_direct_xmit+0x1a3/0xc30 __qdisc_run+0x510/0x17a0 __dev_queue_xmit+0x2215/0x3b10 neigh_connected_output+0x3c2/0x550 ip6_finish_output2+0x55a/0x1550 ip6_finish_output+0x6b9/0x1270 ip6_output+0x1f1/0x540 ndisc_send_skb+0xa63/0x1890 ndisc_send_rs+0x132/0x6f0 addrconf_rs_timer+0x3f1/0x870 call_timer_fn+0x1a0/0x580 expire_timers+0x29b/0x4b0 run_timer_softirq+0x326/0x910 __do_softirq+0x1d4/0x905 irq_exit_rcu+0xb7/0x120 sysvec_apic_timer_interrupt+0x97/0xc0 </IRQ> <TASK> asm_sysvec_apic_timer_interrupt+0x1a/0x20 RIP: 0010:intel_idle_hlt+0x23/0x30 Code: 1f 84 00 00 00 00 00 f3 0f 1e fa 41 54 41 89 d4 0f 1f 44 00 00 66 90 0f 1f 44 00 00 0f 00 2d c4 9f ab 00 0f 1f 44 00 00 fb f4 <fa> 44 89 e0 41 5c c3 66 0f 1f 44 00 00 f3 0f 1e fa 41 54 41 89 d4 RSP: 0018:ffffc90000197d78 EFLAGS: 00000246 RAX: 00000000000a83c3 RBX: ffffe8ffffd09c50 RCX: ffffffff8a22d8e5 RDX: 0000000000000001 RSI: ffffffff8d3f8080 RDI: ffffe8ffffd09c50 RBP: ffffffff8d3f8080 R08: 0000000000000001 R09: ffffed1026ba6d9d R10: ffff888135d36ceb R11: 0000000000000001 R12: 0000000000000001 R13: ffffffff8d3f8100 R14: 0000000000000001 R15: 0000000000000000 cpuidle_enter_state+0xd3/0x6f0 cpuidle_enter+0x4e/0xa0 do_idle+0x2fe/0x3c0 cpu_startup_entry+0x18/0x20 start_secondary+0x200/0x290 secondary_startup_64_no_verify+0x167/0x16b </TASK> Allocated by task 939: kasan_save_stack+0x22/0x40 kasan_set_track+0x25/0x30 __kasan_slab_alloc+0x7f/0x90 kmem_cache_alloc_node+0x1cd/0x410 kmalloc_reserve+0x165/0x270 __alloc_skb+0x129/0x330 inet6_ifa_notify+0x118/0x230 __ipv6_ifa_notify+0x177/0xbe0 addrconf_dad_completed+0x133/0xe00 addrconf_dad_work+0x764/0x1390 process_one_work+0xa32/0x16f0 worker_thread+0x67d/0x10c0 kthread+0x344/0x440 ret_from_fork+0x1f/0x30 The buggy address belongs to the object at ffff888111145800 which belongs to the cache skbuff_small_head of size 640 The buggy address is located 239 bytes inside of freed 640-byte region [ffff888111145800, ffff888111145a80) As commit f855691975bb ("xfrm6: Fix the nexthdr offset in _decode_session6.") showed, xfrm_decode_session was originally intended only for the receive path.

[PATCH openEuler-1.0-LTS] i40e: add validation for ring_len param
by Ziming Du 31 Oct '25

31 Oct '25

From: Lukasz Czapnik <lukasz.czapnik(a)intel.com> mainline inclusion from mainline-v6.17 commit 55d225670def06b01af2e7a5e0446fbe946289e8 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID228U CVE: CVE-2025-39973 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- The `ring_len` parameter provided by the virtual function (VF) is assigned directly to the hardware memory context (HMC) without any validation. To address this, introduce an upper boundary check for both Tx and Rx queue lengths. The maximum number of descriptors supported by the hardware is 8k-32. Additionally, enforce alignment constraints: Tx rings must be a multiple of 8, and Rx rings must be a multiple of 32.

[PATCH openEuler-1.0-LTS] wifi: brcmfmac: Fix potential shift-out-of-bounds in brcmf_fw_alloc_request()

31 Oct '25

From: Minsuk Kang <linuxlovemin(a)yonsei.ac.kr> stable inclusion from stable-v4.19.270 commit 9d2f70fa2c7cc6c73a420ff15682454782d3d6f6 category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID0VIT CVE: CVE-2022-50551 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 81d17f6f3331f03c8eafdacea68ab773426c1e3c ] This patch fixes a shift-out-of-bounds in brcmfmac that occurs in BIT(chiprev) when a 'chiprev' provided by the device is too large. It should also not be equal to or greater than BITS_PER_TYPE(u32) as we do bitwise AND with a u32 variable and BIT(chiprev). The patch adds a check that makes the function return NULL if that is the case. Note that the NULL case is later handled by the bus-specific caller, brcmf_usb_probe_cb() or brcmf_usb_reset_resume(), for example. Found by a modified version of syzkaller.

[PATCH openEuler-1.0-LTS] wifi: brcmfmac: ensure CLM version is null-terminated to prevent stack-out-of-bounds
by Ziming Du 31 Oct '25

From: Jisoo Jang <jisoo.jang(a)yonsei.ac.kr> stable inclusion from stable-v4.19.276 commit 3b173b4ad9c001a555f44adc7836d6fe3afbe9ec category: bugfix bugzilla: https://gitee.com/src-openeuler/kernel/issues/ID0UBV CVE: CVE-2023-53582 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 660145d708be52f946a82e5b633c020f58f996de ] Fix a stack-out-of-bounds read in brcmfmac that occurs when 'buf' that is not null-terminated is passed as an argument of strreplace() in brcmf_c_preinit_dcmds(). This buffer is filled with a CLM version string by memcpy() in brcmf_fil_iovar_data_get(). Ensure buf is null-terminated. Found by a modified version of syzkaller.
