| Adobe Framemaker is affected by a Use After Free vulnerability that could result in arbitrary code execution in the context of the current user. Exploitation of this issue requires user interaction in that a victim must open a malicious file. |
| Text::CSV_XS versions from 1.46 before 1.65 for Perl have a use-after-free of bind_columns variables when skip_empty_rows skips an empty line in getline.
With bind_columns, the parser writes each field into the caller's own scalar without taking a reference to it. When skip_empty_rows skips an empty last line, the parser frees the current field scalar without checking whether it is bound, dropping one reference from the application's variable. The "eof" mode does the same on any empty line.
The variable is then freed while the application still references it, so later code uses freed memory and can crash the process. |
| Use after free in Windows Hyper-V allows an authorized attacker to execute code locally. |
| Use after free in iOSWeb in Google Chrome on on iOS prior to 156.0.8078.47 allowed a remote attacker to execute arbitrary code inside the sandbox via a crafted HTML page. (Chromium security severity: Medium) |
| Use after free in Windows Win32 Kernel Subsystem allows an authorized attacker to elevate privileges locally. |
| In the Linux kernel, the following vulnerability has been resolved:
ACPI: platform: Use acpi_bus_get_primary_device()
The acpi_get_first_physical_node() usage in acpi_platform_fill_resource()
and acpi_create_platform_device() is generally unsafe because in theory
the device returned by it may be freed at any time [1].
It is also inefficient because acpi_get_first_physical_node() is called
multiple times for the same argument which can be avoided.
Address these issues by using acpi_bus_get_primary_device() instead of
acpi_get_first_physical_node() and adjusting the code to call it just
once at the beginning of and acpi_create_platform_device() and drop
the device reference acquired by it upon the return from that function. |
| Use after free in Windows Shell allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows NTFS allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Spaceport.sys allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Win32K allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Hello allows an authorized attacker to elevate privileges locally. |
| ImageMagick is free and open-source software used for editing and manipulating digital images. Prior to 7.1.2-30 and 6.9.13-55, when ImageMagick is built without Cairo support, a crafted RSVG image that reaches a resource limit can cause the RSVG decoder to free image state twice and then use freed memory, crashing the process. This issue is fixed in versions 7.1.2-30 and 6.9.13-55. |
| Memory safety bug fixed in Thunderbird 152. This vulnerability was fixed in Firefox 152, Firefox ESR 140.12, Thunderbird 152, and Thunderbird 140.12. |
| Memory safety bug fixed in Thunderbird 152. This vulnerability was fixed in Firefox 152, Firefox ESR 140.12, Thunderbird 152, and Thunderbird 140.12. |
| Memory safety bug fixed in Thunderbird 152. This vulnerability was fixed in Firefox 152, Firefox ESR 140.12, Thunderbird 152, and Thunderbird 140.12. |
| Memory safety bugs present in Thunderbird ESR 140.10.1 and Thunderbird 150.0.1. Some of these bugs showed evidence of memory corruption and we presume that with enough effort some of these could have been exploited to run arbitrary code. This vulnerability was fixed in Firefox 150.0.2, Firefox ESR 140.10.2, Firefox ESR 115.35.2, Thunderbird 150.0.2, and Thunderbird 140.10.2. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Overlay Filter allows an authorized attacker to elevate privileges locally. |
| Use after free in Windows Win32K allows an authorized attacker to elevate privileges locally. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_core: Serialize SCO and ISO scheduling with teardown
hci_low_sent() selects a connection under RCU but drops the read lock
before calculating its quota and returning it to the scheduler. The
connection is then used without lifetime protection by hci_sched_iso()
and hci_sched_sco().
After the TX worker drops the RCU read lock, hci_abort_conn_sync() on
hdev->req_workqueue can remove the connection from the hash, complete
synchronize_rcu(), purge its queues and release it. The TX worker on
hdev->workqueue can then access the freed connection in hci_quote_sent()
or while dequeuing packets and updating conn->sent.

Hold hci_dev_lock() across connection selection and transmission in both
SCO and ISO scheduling, serializing them with connection teardown. This
also prevents queuing completion timestamps after the connection queues
have been purged. Extending RCU across transmission would be unsafe
because the transmit path can sleep. Keep the ISO timeout check outside
the mutex since hci_link_tx_to() takes it itself.
The preceding channel fix already holds this mutex in the ACL and LE
schedulers, which call the SCO scheduler between packets. Move the SCO
body to __hci_sched_sco(), assert that its caller holds the mutex, and
use it directly from these locked paths. Keep a locking hci_sched_sco()
wrapper for the direct calls from hci_tx_work(). This avoids recursively
acquiring the device mutex while preserving the scheduling order.
Remove the obsolete claim that connection removal disables TX. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: fix mesh fast xmit path deletion UAF
mesh_fast_tx_cache() stores raw mesh_path pointers. Path deletion
flushes the cache and then frees the path with kfree_rcu(), but a
lookup that already holds the path can insert a new cache entry
after the flush. The cache then points at freed memory.
Set MESH_PATH_DELETED before flushing, and skip inserting a cache
entry if the path or MPP path is already deleted. Check this under
the cache walk lock so it is ordered with the flush. Use WRITE_ONCE()
for the deletion flag updates because the cache check reads flags
without taking state_lock. |
