CVSS v3.1 |
| Legrand BTicino Driver Manager F454 1.0.51 contains multiple web vulnerabilities that allow attackers to perform administrative actions without proper request validation. Attackers can exploit cross-site request forgery to change passwords and inject stored cross-site scripting payloads through unvalidated GET parameters. |
| Ross Video DashBoard 8.5.1 contains an elevation of privileges vulnerability that allows authenticated users to modify executable files due to improper permission settings. Attackers can exploit the 'M' or 'C' flags for 'Authenticated Users' group to replace the DashBoard.exe binary with a malicious executable. |
| Beward N100 H.264 VGA IP Camera M2.1.6 contains an authenticated file disclosure vulnerability that allows attackers to read arbitrary system files via the 'READ.filePath' parameter. Attackers can exploit the fileread script or SendCGICMD API to access sensitive files like /etc/passwd and /etc/issue by supplying absolute file paths. |
| Beward N100 H.264 VGA IP Camera M2.1.6 contains a cross-site request forgery vulnerability that allows attackers to perform administrative actions without proper request validation. Attackers can craft a malicious web page with a hidden form to add an admin user by tricking a logged-in user into submitting the form. |
| Beward N100 M2.1.6.04C014 contains an unauthenticated vulnerability that allows remote attackers to access live video streams without credentials. Attackers can directly retrieve the camera's RTSP stream by exploiting the lack of authentication in the video access mechanism. |
| devolo dLAN 500 AV Wireless+ 3.1.0-1 contains an authentication bypass vulnerability that allows attackers to enable hidden services through the htmlmgr CGI script. Attackers can enable telnet and remote shell services, reboot the device, and gain root access without a password by manipulating system configuration parameters. |
| Devolo dLAN 500 AV Wireless+ 3.1.0-1 contains a cross-site request forgery vulnerability that allows attackers to perform administrative actions without proper request validation. Attackers can craft malicious web pages that trigger unauthorized configuration changes by exploiting predictable URL actions when a logged-in user visits the site. |
| VideoFlow Digital Video Protection DVP 2.10 contains an authenticated remote code execution vulnerability that allows attackers to execute system commands with root privileges. Attackers can exploit the vulnerability through a cross-site request forgery (CSRF) mechanism to gain unauthorized system access. |
| VideoFlow Digital Video Protection DVP 2.10 contains an authenticated directory traversal vulnerability that allows attackers to access arbitrary system files through unvalidated 'ID' parameters. Attackers can exploit multiple Perl scripts like downloadsys.pl to read sensitive files by manipulating directory path traversal in download requests. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/msm: fix NULL-deref on irq uninstall
In case of early initialisation errors and on platforms that do not use
the DPU controller, the deinitilisation code can be called with the kms
pointer set to NULL.
Patchwork: https://patchwork.freedesktop.org/patch/525104/ |
| In the Linux kernel, the following vulnerability has been resolved:
tracing/user_events: Ensure write index cannot be negative
The write index indicates which event the data is for and accesses a
per-file array. The index is passed by user processes during write()
calls as the first 4 bytes. Ensure that it cannot be negative by
returning -EINVAL to prevent out of bounds accesses.
Update ftrace self-test to ensure this occurs properly. |
| In the Linux kernel, the following vulnerability has been resolved:
maple_tree: fix potential out-of-bounds access in mas_wr_end_piv()
Check the write offset end bounds before using it as the offset into the
pivot array. This avoids a possible out-of-bounds access on the pivot
array if the write extends to the last slot in the node, in which case the
node maximum should be used as the end pivot.
akpm: this doesn't affect any current callers, but new users of mapletree
may encounter this problem if backported into earlier kernels, so let's
fix it in -stable kernels in case of this. |
| In the Linux kernel, the following vulnerability has been resolved:
serial: sprd: Fix DMA buffer leak issue
Release DMA buffer when _probe() returns failure to avoid memory leak. |
| In the Linux kernel, the following vulnerability has been resolved:
vfio/type1: fix cap_migration information leak
Fix an information leak where an uninitialized hole in struct
vfio_iommu_type1_info_cap_migration on the stack is exposed to userspace.
The definition of struct vfio_iommu_type1_info_cap_migration contains a hole as
shown in this pahole(1) output:
struct vfio_iommu_type1_info_cap_migration {
struct vfio_info_cap_header header; /* 0 8 */
__u32 flags; /* 8 4 */
/* XXX 4 bytes hole, try to pack */
__u64 pgsize_bitmap; /* 16 8 */
__u64 max_dirty_bitmap_size; /* 24 8 */
/* size: 32, cachelines: 1, members: 4 */
/* sum members: 28, holes: 1, sum holes: 4 */
/* last cacheline: 32 bytes */
};
The cap_mig variable is filled in without initializing the hole:
static int vfio_iommu_migration_build_caps(struct vfio_iommu *iommu,
struct vfio_info_cap *caps)
{
struct vfio_iommu_type1_info_cap_migration cap_mig;
cap_mig.header.id = VFIO_IOMMU_TYPE1_INFO_CAP_MIGRATION;
cap_mig.header.version = 1;
cap_mig.flags = 0;
/* support minimum pgsize */
cap_mig.pgsize_bitmap = (size_t)1 << __ffs(iommu->pgsize_bitmap);
cap_mig.max_dirty_bitmap_size = DIRTY_BITMAP_SIZE_MAX;
return vfio_info_add_capability(caps, &cap_mig.header, sizeof(cap_mig));
}
The structure is then copied to a temporary location on the heap. At this point
it's already too late and ioctl(VFIO_IOMMU_GET_INFO) copies it to userspace
later:
int vfio_info_add_capability(struct vfio_info_cap *caps,
struct vfio_info_cap_header *cap, size_t size)
{
struct vfio_info_cap_header *header;
header = vfio_info_cap_add(caps, size, cap->id, cap->version);
if (IS_ERR(header))
return PTR_ERR(header);
memcpy(header + 1, cap + 1, size - sizeof(*header));
return 0;
}
This issue was found by code inspection. |
| In the Linux kernel, the following vulnerability has been resolved:
nilfs2: fix WARNING in mark_buffer_dirty due to discarded buffer reuse
A syzbot stress test using a corrupted disk image reported that
mark_buffer_dirty() called from __nilfs_mark_inode_dirty() or
nilfs_palloc_commit_alloc_entry() may output a kernel warning, and can
panic if the kernel is booted with panic_on_warn.
This is because nilfs2 keeps buffer pointers in local structures for some
metadata and reuses them, but such buffers may be forcibly discarded by
nilfs_clear_dirty_page() in some critical situations.
This issue is reported to appear after commit 28a65b49eb53 ("nilfs2: do
not write dirty data after degenerating to read-only"), but the issue has
potentially existed before.
Fix this issue by checking the uptodate flag when attempting to reuse an
internally held buffer, and reloading the metadata instead of reusing the
buffer if the flag was lost. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: ath11k: Add missing hw_ops->get_ring_selector() for IPQ5018
During sending data after clients connected, hw_ops->get_ring_selector()
will be called. But for IPQ5018, this member isn't set, and the

| In the Linux kernel, the following vulnerability has been resolved:
media: mediatek: vcodec: fix resource leaks in vdec_msg_queue_init()
If we encounter any error in the vdec_msg_queue_init() then we need
to set "msg_queue->wdma_addr.size = 0;". Normally, this is done
inside the vdec_msg_queue_deinit() function. However, if the
first call to allocate &msg_queue->wdma_addr fails, then the
vdec_msg_queue_deinit() function is a no-op. For that situation, just
set the size to zero explicitly and return.
There were two other error paths which did not clean up before returning.
Change those error paths to goto mem_alloc_err. |
