| In the Linux kernel, the following vulnerability has been resolved:
batman-adv: bla: prevent use-after-free when deleting claims
When batadv_bla_del_backbone_claims() removes all claims for a backbone, it
does this by dropping the link entry in the hash list. This list entry
itself was one of the references which need to be dropped at the same time
via batadv_claim_put().
But the batadv_claim_put() must not be done before the last access to the
claim object in this function. Otherwise the claim might be freed already
by the batadv_claim_release() function before the list entry was dropped. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: appletb-kbd: fix UAF in inactivity-timer cleanup path
Commit 38224c472a03 ("HID: appletb-kbd: fix slab use-after-free bug in
appletb_kbd_probe") added timer_delete_sync(&kbd->inactivity_timer) to
both the probe close_hw error path and appletb_kbd_remove(), but the
way it was wired in left the inactivity timer reachable during driver
tear-down via two distinct windows.
Window A -- put_device() before timer_delete_sync():
put_device(&kbd->backlight_dev->dev);
timer_delete_sync(&kbd->inactivity_timer);
The inactivity_timer softirq reads kbd->backlight_dev and calls
backlight_device_set_brightness() -> mutex_lock(&ops_lock). If a
concurrent hid_appletb_bl unbind drops the last devm reference
between these two calls, the backlight_device is freed and the
mutex_lock() touches freed memory.
Window B -- backlight cleanup before hid_hw_stop():
if (kbd->backlight_dev) {
timer_delete_sync(...);
put_device(...);
}
hid_hw_close(hdev);
hid_hw_stop(hdev);
Even after Window A is closed, hid_hw_close()/hid_hw_stop() still run
afterwards, so a late ".event" callback from the HID core (USB URB
completion on real Apple hardware) can arrive after
timer_delete_sync() drained the softirq but before put_device() drops
the reference. That callback reaches reset_inactivity_timer(), which
calls mod_timer() and re-arms the timer. The freshly re-armed timer
can then fire on the about-to-be-freed backlight_device.
Both windows produce the same KASAN slab-use-after-free:

(concurrent hid_appletb_bl unbind path)
Close both windows at once by reworking the tear-down in
appletb_kbd_remove() and in the probe close_hw error path so that
1) hid_hw_close()/hid_hw_stop() run before the backlight cleanup,
guaranteeing no further .event callback can fire and re-arm the
timer, and
2) inside the "if (kbd->backlight_dev)" block, timer_delete_sync()
runs before put_device(), so the softirq is drained before the
final reference is dropped. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: Add bounds checking to ib_{get,set}_value
The uvd/vce/vcn code accesses the IB at predefined offsets without
checking that the IB is large enough. Check the bounds here. The caller
is responsible for making sure it can handle arbitrary return values.
Also make the idx a uint32_t to prevent overflows causing the condition
to fail. |
| Use after free in Extensions in Google Chrome prior to 149.0.7827.53 allowed a remote attacker to execute arbitrary code inside a sandbox via a crafted HTML page. (Chromium security severity: Low) |
| Shenzhen Tenda Technology Co., Ltd Tenda G0 v15.11.0.5 was discovered to contain multiple buffer overflows in the Saveqqlist function via the qqStr and markStr parameters. These vulnerabilities allow attackers to cause a Denial of Service (DoS) via a crafted HTTP request. |
| The $_internalApplyOplogUpdate aggregation pipeline stage can be used to execute a document diff containing a malformed binary diff to return memory out-of-bounds or crash the server. $_internalApplyOplogUpdate can be executed by any authenticated user with access to the aggregate command. |
| In the Linux kernel, the following vulnerability has been resolved:
spi: mpc52xx: fix use-after-free on unbind
The state machine work is scheduled by the interrupt handler and
therefore needs to be cancelled after disabling interrupts to avoid a
potential use-after-free. |
| An inclusion of functionality from untrusted control sphere vulnerability in OpenSSL configuration in Synology Active Backup for Business Recovery Media Creator before 2.5.0-2081 allows local users to execute arbitrary code via unspecified vectors. |
| An unauthenticated user on the local network can gain control of the router and make unauthorized changes to its operation. |
| SimpleSAMLphp-casserver is a CAS 1.0 and 2.0 compliant CAS server in the form of a SimpleSAMLphp module. Prior to version 7.0.3, simplesamlphp-module-casserver builds file paths for the file-based CAS ticket store by directly concatenating the configured ticket directory with an attacker-controlled ticket identifier. Public CAS validation/proxy endpoints pass attacker-controlled ticket / pgt query parameters into this store. In deployments using FileSystemTicketStore, a remote attacker can use path traversal sequences such as ../target.serialized to make the CAS server read and unserialize files outside the ticket directory. In the CAS 1.0 validation flow, the same attacker-selected path is also passed to deleteTicket() immediately after getTicket() returns, which can delete the target file when it is readable by the PHP process, deletable under the PHP process filesystem permissions, and unserializes to a value compatible with the ?array return type. This issue has been patched in version 7.0.3. |
| BuddyPress 14.4.0 contains an insecure direct object reference vulnerability in the messages REST API that allows authenticated attackers to access arbitrary private message threads by supplying a user_id parameter in the request. Attackers can pass another user's identifier to the get_item_permissions_check method, which validates the supplied user_id instead of the logged-in user and is reused by the update and delete handlers, to read, reply to, or delete any user's private messages. |
| Inappropriate implementation in Views in Google Chrome on Linux prior to 149.0.7827.103 allowed a remote attacker who had compromised the renderer process to potentially perform a sandbox escape via a crafted HTML page. (Chromium security severity: High) |
| An information disclosure vulnerability in the /api/v1/user/info endpoint of AgentChat v2.3.0 allows unauthenticated attackers to obtain sensitive information, including SHA256 password hashes, via enumerating user IDs. |
| Untrusted search path in Windows Storage allows an authorized attacker to elevate privileges locally. |
| Uncontrolled resource consumption in ASP.NET Core allows an unauthorized attacker to deny service over a network. |
| Improper authorization in .NET allows an authorized attacker to elevate privileges locally. |
| Protection mechanism failure in Windows Boot Manager allows an authorized attacker to bypass a security feature locally. |
| A flaw was found in the gdk-pixbuf library. This heap-based buffer overflow vulnerability occurs in the JPEG image loader due to improper validation of color component counts when processing a specially crafted JPEG image. A remote attacker can exploit this flaw without user interaction, for example, via thumbnail generation. Successful exploitation leads to application crashes and denial of service (DoS) conditions. |
| A segment fault (SEGV) flaw was found in libtiff that could be triggered by passing a crafted tiff file to the TIFFReadRGBATileExt() API. This flaw allows a remote attacker to cause a heap-buffer overflow, leading to a denial of service. |
| Spring Data REST's JSON Patch (application/json-patch+json) implementation does not apply the write-access filter to intermediate path segments when resolving a multi-segment JSON Pointer.
Affected versions:
Spring Data REST 3.7.0 through 3.7.19; 4.3.0 through 4.3.16; 4.4.0 through 4.4.14; 4.5.0 through 4.5.11; 5.0.0 through 5.0.5. |
