In the Linux kernel, the following vulnerability has been resolved: wifi: brcmfmac: Check the count value of channel spec to prevent out-of-bounds reads This patch fixes slab-out-of-bounds reads in brcmfmac that occur in brcmf_construct_chaninfo() and brcmf_enable_bw40_2g() when the count value of channel specifications provided by the device is greater than the length of 'list->element[]', decided by the size of the 'list' allocated with kzalloc(). The patch adds checks that make the functions free the buffer and return -EINVAL if that is the case. Note that the negative return is handled by the caller, brcmf_setup_wiphybands() or brcmf_cfg80211_attach(). Found by a modified version of syzkaller.

Therefore, the two locks can     be concurrent. ctrl_cdev_ioctl contains two operations: ubi_attach and ubi_detach. ubi_detach is bug-free     because it uses reference counting to prevent concurrency. However, uif_init and uif_close in ubi_attach     may race with ubi_cdev_ioctl. uif_init will race with ubi_cdev_ioctl as in the following stack. cpu1 cpu2     cpu3 _______________________|________________________|______________________ ctrl_cdev_ioctl     ubi_attach_mtd_dev uif_init ubi_cdev_ioctl ubi_create_volume cdev_device_add ubi_add_volume // sysfs exist     kill_volumes ubi_cdev_ioctl ubi_remove_volume cdev_device_del // first free ubi_free_volume cdev_del //     double free cdev_device_del And uif_close will race with ubi_cdev_ioctl as in the following stack. cpu1     cpu2 cpu3 _______________________|________________________|______________________ ctrl_cdev_ioctl     ubi_attach_mtd_dev uif_init ubi_cdev_ioctl ubi_create_volume cdev_device_add ubi_debugfs_init_dev //error     goto out_uif; uif_close kill_volumes ubi_cdev_ioctl ubi_remove_volume cdev_device_del // first free     ubi_free_volume // double free The cause of this problem is that commit 714fb87e8bc0 make device     available before it becomes accessible via sysfs. Therefore, we roll back the modification. We will fix     the race condition between ubi device creation and udev by removing ubi_get_device in vol_attribute_show     and dev_attribute_show.This avoids accessing uninitialized ubi_devices[ubi_num]. ubi_get_device is used to     prevent devices from being deleted during sysfs execution. However, now kernfs ensures that devices will     not be deleted before all reference counting are released. The key process is shown in the following     stack. device_del device_remove_attrs device_remove_groups sysfs_remove_groups sysfs_remove_group     remove_files kernfs_remove_by_name kernfs_remove_by_name_ns __kernfs_remove kernfs_drain (CVE-2021-47634)

  - In the Linux kernel, the following vulnerability has been resolved: irqchip/gic-v3: Fix error handling in     gic_populate_ppi_partitions of_get_child_by_name() returns a node pointer with refcount incremented, we     should use of_node_put() on it when not need anymore.

The CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS7:CLSA-2026:1783337441 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: IB/qib: Protect from buffer overflow     in struct qib_user_sdma_pkt fields Overflowing either addrlimit or bytes_togo can allow userspace to     trigger a buffer overflow of kernel memory. Check for overflows in all the places doing math on user     controlled buffers. (CVE-2021-47485)

  - In the Linux kernel, the following vulnerability has been resolved: nfsd: fix use-after-free due to     delegation race A delegation break could arrive as soon as we've called vfs_setlease. A delegation break     runs a callback which immediately (in nfsd4_cb_recall_prepare) adds the delegation to del_recall_lru. If     we then exit nfs4_set_delegation without hashing the delegation, it will be freed as soon as the callback     is done with it, without ever being removed from del_recall_lru. Symptoms show up later as use-after-free     or list corruption warnings, usually in the laundromat thread. I suspect aba2072f4523 nfsd: grant read     delegations to clients holding writes made this bug easier to hit, but I looked as far back as v3.0 and     it looks to me it already had the same problem. So I'm not sure where the bug was introduced; it may have     been there from the beginning. (CVE-2021-47506)

    In the Linux kernel, the following vulnerability has been resolved:

    wifi: brcmfmac: Check the count value of channel spec to prevent out-of-bounds reads

    This patch fixes slab-out-of-bounds reads in brcmfmac that occur in     brcmf_construct_chaninfo() and brcmf_enable_bw40_2g() when the count     value of channel specifications provided by the device is greater than     the length of 'list->element[]', decided by the size of the 'list'     allocated with kzalloc(). The patch adds checks that make the functions     free the buffer and return -EINVAL if that is the case. Note that the     negative return is handled by the caller, brcmf_setup_wiphybands() or     brcmf_cfg80211_attach().

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-987686 advisory.

    In the Linux kernel, the following vulnerability has been resolved:

    wifi: brcmfmac: Check the count value of channel spec to prevent out-of-bounds reads

    This patch fixes slab-out-of-bounds reads in brcmfmac that occur in     brcmf_construct_chaninfo() and brcmf_enable_bw40_2g() when the count     value of channel specifications provided by the device is greater than     the length of 'list->element[]', decided by the size of the 'list'     allocated with kzalloc(). The patch adds checks that make the functions     free the buffer and return -EINVAL if that is the case. Note that the     negative return is handled by the caller, brcmf_setup_wiphybands() or     brcmf_cfg80211_attach().

    Found by a modified version of syzkaller.
