| A security vulnerability has been detected in Tomofun Furbo 360 up to FB0035_FW_036. This issue affects some unknown processing of the component Account Handler. Such manipulation leads to server-side request forgery. The attack can be executed remotely. This attack is characterized by high complexity. The exploitability is assessed as difficult. The vendor was contacted early about this disclosure but did not respond in any way. |
| In the Linux kernel, the following vulnerability has been resolved:
btrfs: zoned: fix extent range end unlock in cow_file_range()
Running generic/751 on the for-next branch often results in a hang like
below. They are both stack by locking an extent. This suggests someone
forget to unlock an extent.

This happens because we have another success path for the zoned mode. When
there is no active zone available, btrfs_reserve_extent() returns
-EAGAIN. In this case, we have two reactions.
(1) If the given range is never allocated, we can only wait for someone
to finish a zone, so wait on BTRFS_FS_NEED_ZONE_FINISH bit and retry
afterward.
(2) Or, if some allocations are already done, we must bail out and let
the caller to send IOs for the allocation. This is because these IOs
may be necessary to finish a zone.
The commit 06f364284794 ("btrfs: do proper folio cleanup when
cow_file_range() failed") moved the unlock code from the inside of the
loop to the outside. So, previously, the allocated extents are unlocked
just after the allocation and so before returning from the function.
However, they are no longer unlocked on the case (2) above. That caused
the hang issue.
Fix the issue by modifying the 'end' to the end of the allocated
range. Then, we can exit the loop and the same unlock code can properly
handle the case. |
| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: fix out-of-bounds in parse_sec_desc()
If osidoffset, gsidoffset and dacloffset could be greater than smb_ntsd
struct size. If it is smaller, It could cause slab-out-of-bounds.
And when validating sid, It need to check it included subauth array size. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: corsair-void: Update power supply values with a unified work handler
corsair_void_process_receiver can be called from an interrupt context,
locking battery_mutex in it was causing a kernel panic.
Fix it by moving the critical section into its own work, sharing this
work with battery_add_work and battery_remove_work to remove the need
for any locking |
| A vulnerability was detected in Tomofun Furbo 360 up to FB0035_FW_036. Impacted is an unknown function of the component Audio Handler. Performing manipulation results in race condition. The attack is possible to be carried out remotely. The vendor was contacted early about this disclosure but did not respond in any way. |

| In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Fix NULL dereference in ni_write_inode
Syzbot reports a NULL dereference in ni_write_inode.
When creating a new inode, if allocation fails in mi_init function
(called in mi_format_new function), mi->mrec is set to NULL.
In the error path of this inode creation, mi->mrec is later
dereferenced in ni_write_inode.
Add a NULL check to prevent NULL dereference. |
