The root cause of this was that there was a free (dma_free_attrs) in the
interrupt context. There was a device discovery/fabric scan in
progress. A module unload was issued which set the UNLOADING flag. As
part of the discovery, after receiving an interrupt a work queue was
scheduled (which involved a work to be queued). Since the UNLOADING
flag is set, the work item was not allocated and the mapped memory had
to be freed. The free occurred in interrupt context leading to system
crash. Delay the driver unload until the fabric scan is complete to
avoid the crash.

In the Linux kernel, the following vulnerability has been resolved:
nilfs2: Fix potential block overflow that cause system hang
When a user executes the FITRIM command, an underflow can occur when
calculating nblocks if end_block is too small. Since nblocks is of
type sector_t, which is u64, a negative nblocks value will become a
very large positive integer. This ultimately leads to the block layer
function __blkdev_issue_discard() taking an excessively long time to
process the bio chain, and the ns_segctor_sem lock remains held for a
long period. This prevents other tasks from acquiring the ns_segctor_sem
lock, resulting in the hang reported by syzbot in [1].
If the ending block is too small, typically if it is smaller than 4KiB
range, depending on the usage of the segment 0, it may be possible to
attempt a discard request beyond the device size causing the hang.
Exiting successfully and assign the discarded size (0 in this case)
to range->len.
Although the start and len values in the user input range are too small,
a conservative strategy is adopted here to safely ignore them, which is
equivalent to a no-op; it will not perform any trimming and will not
throw an error.

In the Linux kernel, the following vulnerability has been resolved:
hfs: ensure sb->s_fs_info is always cleaned up
When hfs was converted to the new mount api a bug was introduced by
changing the allocation pattern of sb->s_fs_info. If setup_bdev_super()
fails after a new superblock has been allocated by sget_fc(), but before
hfs_fill_super() takes ownership of the filesystem-specific s_fs_info
data it was leaked.
Fix this by freeing sb->s_fs_info in hfs_kill_super().

In the Linux kernel, the following vulnerability has been resolved:
crypto: iaa - Fix out-of-bounds index in find_empty_iaa_compression_mode
The local variable 'i' is initialized with -EINVAL, but the for loop
immediately overwrites it and -EINVAL is never returned.
If no empty compression mode can be found, the function would return the
out-of-bounds index IAA_COMP_MODES_MAX, which would cause an invalid
array access in add_iaa_compression_mode().
Fix both issues by returning either a valid index or -EINVAL.

mayswind ezbookkeeping versions 1.2.0 and earlier contain a critical vulnerability in JSON and XML file import processing. The application fails to validate nesting depth during parsing operations, allowing authenticated attackers to trigger denial of service conditions by uploading deeply nested malicious files. This results in CPU exhaustion, service degradation, or complete service unavailability.
