In the Linux kernel, the following vulnerability has been resolved: wifi: mt7601u: fix an integer underflow Fix an integer underflow that leads to a null pointer dereference in 'mt7601u_rx_skb_from_seg()'. The variable 'dma_len' in the URB packet could be manipulated, which could trigger an integer underflow of 'seg_len' in 'mt7601u_rx_process_seg()'. This underflow subsequently causes the 'bad_frame' checks in 'mt7601u_rx_skb_from_seg()' to be bypassed, eventually leading to a dereference of the pointer 'p', which is a null pointer. Ensure that 'dma_len' is greater than 'min_seg_len'. Found by a modified version of syzkaller.

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1767864313 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: firmware: arm_scpi: Ensure scpi_info     is not assigned if the probe fails When scpi probe fails, at any point, we need to ensure that the     scpi_info is not set and will remain NULL until the probe succeeds. If it is not taken care, then it could     result use-after-free as the value is exported via get_scpi_ops() and could refer to a memory allocated     via devm_kzalloc() but freed when the probe fails. (CVE-2022-50087)

  - In the Linux kernel, the following vulnerability has been resolved: wifi: rtlwifi: Fix global-out-of-     bounds bug in _rtl8812ae_phy_set_txpower_limit() There is a global-out-of-bounds reported by KASAN: BUG:
    KASAN: global-out-of-bounds in _rtl8812ae_eq_n_byte.part.0+0x3d/0x84 [rtl8821ae] Read of size 1 at addr     ffffffffa0773c43 by task NetworkManager/411 CPU: 6 PID: 411 Comm: NetworkManager Tainted: G D 6.1.0-rc8+     #144 e15588508517267d37 Hardware name: QEMU Standard PC (Q35 + ICH9, 2009), Call Trace: <TASK> ...

    </TASK> The root cause of the problem is that the comparison order of prate_section in
    _rtl8812ae_phy_set_txpower_limit() is wrong. The _rtl8812ae_eq_n_byte() is used to compare the first n     bytes of the two strings from tail to head, which causes the problem. In the
    _rtl8812ae_phy_set_txpower_limit(), it was originally intended to meet this requirement by carefully     designing the comparison order. For example, pregulation and pbandwidth are compared in order of     length from small to large, first is 3 and last is 4. However, the comparison order of prate_section     dose not obey such order requirement, therefore when prate_section is HT, when comparing from tail to     head, it will lead to access out of bounds in _rtl8812ae_eq_n_byte(). As mentioned above, the
    _rtl8812ae_eq_n_byte() has the same function as strcmp(), so just strcmp() is enough. Fix it by removing
    _rtl8812ae_eq_n_byte() and use strcmp() barely. Although it can be fixed by adjusting the comparison order     of prate_section, this may cause the value of rate_section to not be from 0 to 5. In addition, commit     21e4b0726dc6 not only moved driver from staging to regular tree, but also added setting txpower limit     function during the driver config phase, so the problem was introduced by this commit.

  - In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix monitor mode bringup     crash When the interface is brought up in monitor mode, it leads to NULL pointer dereference crash. This     crash happens when the packet type is extracted for a SKB. This extraction which is present in the     received msdu delivery path,is not needed for the monitor ring packets since they are all RAW packets.
    Hence appending the flags with RX_FLAG_ONLY_MONITOR to skip that extraction.

  - In the Linux kernel, the following vulnerability has been resolved: PCI: Fix pci_device_is_present() for     VFs by checking PF pci_device_is_present() previously didn't work for VFs because it reads the Vendor and     Device ID, which are 0xffff for VFs, which looks like they aren't present. Check the PF instead. Wei Gong     reported that if virtio I/O is in progress when the driver is unbound or 0 is written to     /sys/.../sriov_numvfs, the virtio I/O operation hangs, which may result in output like this: task:bash     state:D stack: 0 pid: 1773 ppid: 1241 flags:0x00004002 Call Trace: schedule+0x4f/0xc0     blk_mq_freeze_queue_wait+0x69/0xa0 blk_mq_freeze_queue+0x1b/0x20 blk_cleanup_queue+0x3d/0xd0     virtblk_remove+0x3c/0xb0 [virtio_blk] virtio_dev_remove+0x4b/0x80 ... device_unregister+0x1b/0x60     unregister_virtio_device+0x18/0x30 virtio_pci_remove+0x41/0x80 pci_device_remove+0x3e/0xb0 This happened     because pci_device_is_present(VF) returned false in virtio_pci_remove(), so it called     virtio_break_device(). The broken vq meant that vring_interrupt() skipped the vq.callback() that would     have completed the virtio I/O operation via virtblk_done().

  - In the Linux kernel, the following vulnerability has been resolved: ACPICA: Fix error code path in     acpi_ds_call_control_method() A use-after-free in acpi_ps_parse_aml() after a failing invocaion of     acpi_ds_call_control_method() is reported by KASAN [1] and code inspection reveals that next_walk_state     pushed to the thread by acpi_ds_create_walk_state() is freed on errors, but it is not popped from the     thread beforehand. Thus acpi_ds_get_current_walk_state() called by acpi_ps_parse_aml() subsequently     returns it as the new walk state which is incorrect.

The CentOS Linux 8.5 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS8.5:CLSA-2026:1768775579 advisory.

  - An issue was discovered in slc_bump in drivers/net/can/slcan.c in the Linux kernel 3.16 through 5.6.2. It     allows attackers to read uninitialized can_frame data, potentially containing sensitive information from     kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL, aka CID-b9258a2cece4.
    (CVE-2020-11494)

  - An out-of-bounds(OOB) memory access vulnerability was found in vmwgfx driver in     drivers/gpu/vmxgfx/vmxgfx_kms.c in GPU component in the Linux kernel with device file '/dev/dri/renderD128     (or Dxxx)'. This flaw allows a local attacker with a user account on the system to gain privilege, causing     a denial of service(DoS). (CVE-2022-36280)

  - In the Linux kernel, the following vulnerability has been resolved: ath9k_htc: fix potential out of bounds     access with invalid rxstatus->rs_keyix The rxstatus->rs_keyix eventually gets passed to test_bit() so we     need to ensure that it is within the bitmap. drivers/net/wireless/ath/ath9k/common.c:46     ath9k_cmn_rx_accept() error: passing untrusted data 'rx_stats->rs_keyix' to 'test_bit()' (CVE-2022-49503)

  - In the Linux kernel, the following vulnerability has been resolved: ata: libata-transport: fix double     ata_host_put() in ata_tport_add() In the error path in ata_tport_add(), when calling put_device(),     ata_tport_release() is called, it will put the refcount of 'ap->host'. And then ata_host_put() is called     again, the refcount is decreased to 0, ata_host_release() is called, all ports are freed and set to null.
    When unbinding the device after failure, ata_host_stop() is called to release the resources, it leads a     null-ptr-deref(), because all the ports all freed and null.

    wifi: mt7601u: fix an integer underflow

    Fix an integer underflow that leads to a null pointer dereference in     'mt7601u_rx_skb_from_seg()'. The variable 'dma_len' in the URB packet     could be manipulated, which could trigger an integer underflow of     'seg_len' in 'mt7601u_rx_process_seg()'. This underflow subsequently     causes the 'bad_frame' checks in 'mt7601u_rx_skb_from_seg()' to be     bypassed, eventually leading to a dereference of the pointer 'p', which     is a null pointer.

    Ensure that 'dma_len' is greater than 'min_seg_len'.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - wifi: mt7601u: fix an integer underflow Fix an integer underflow that leads to a null pointer dereference     in 'mt7601u_rx_skb_from_seg()'. The variable 'dma_len' in the URB packet could be manipulated, which could     trigger an integer underflow of 'seg_len' in 'mt7601u_rx_process_seg()'. This underflow subsequently     causes the 'bad_frame' checks in 'mt7601u_rx_skb_from_seg()' to be bypassed, eventually leading to a     dereference of the pointer 'p', which is a null pointer. Ensure that 'dma_len' is greater than     'min_seg_len'. Found by a modified version of syzkaller.
