| In the Linux kernel, the following vulnerability has been resolved:
net/x25: Fix skb leak in x25_lapb_receive_frame()
x25_lapb_receive_frame() using skb_copy() to get a private copy of
skb, the new skb should be freed in the undersized/fragmented skb
error handling path. Otherwise there is a memory leak. |
| In the Linux kernel, the following vulnerability has been resolved:
mmc: sdhci-pci: Fix possible memory leak caused by missing pci_dev_put()
pci_get_device() will increase the reference count for the returned
pci_dev. We need to use pci_dev_put() to decrease the reference count
before amd_probe() returns. There is no problem for the 'smbus_dev ==
NULL' branch because pci_dev_put() can also handle the NULL input
parameter case. |
| In the Linux kernel, the following vulnerability has been resolved:
Input: i8042 - fix leaking of platform device on module removal
Avoid resetting the module-wide i8042_platform_device pointer in
i8042_probe() or i8042_remove(), so that the device can be properly
destroyed by i8042_exit() on module unload. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: adc: at91_adc: fix possible memory leak in at91_adc_allocate_trigger()
If iio_trigger_register() returns error, it should call iio_trigger_free()
to give up the reference that hold in iio_trigger_alloc(), so that it can
call iio_trig_release() to free memory when the refcount hit to 0. |
| In the Linux kernel, the following vulnerability has been resolved:
iio: trigger: sysfs: fix possible memory leak in iio_sysfs_trig_init()
dev_set_name() allocates memory for name, it need be freed
when device_add() fails, call put_device() to give up the
reference that hold in device_initialize(), so that it can
be freed in kobject_cleanup() when the refcount hit to 0.
Fault injection test can trigger this:

| Late Release of Memory after Effective Lifetime vulnerability in Apache HTTP Server.
This issue affects Apache HTTP Server: from 2.4.17 up to 2.4.63.
Users are recommended to upgrade to version 2.4.64, which fixes the issue. |
| libLAS 1.8.1 contains a memory leak vulnerability in /libLAS/apps/ts2las.cpp. |
| freeglut through 3.4.0 was discovered to contain a memory leak via the menuEntry variable in the glutAddMenuEntry function. |
| freeglut 3.4.0 was discovered to contain a memory leak via the menuEntry variable in the glutAddSubMenu function. |
| Gifsicle through 1.94, if deployed in a way that allows untrusted input to affect Gif_Realloc calls, might allow a denial of service (memory consumption). NOTE: this has been disputed by multiple parties because the Gifsicle code is not commonly used for unattended operation in which new input arrives for a long-running process, does not ship with functionality to link it into another application as a library, and does not have realistic use cases in which an adversary controls the entire command line. |
| A memory leak in ImageMagick 7.0.10-45 and 6.9.11-22 allows remote attackers to perform a denial of service via the "identify -help" command. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Fix memory leak in create_process failure
Fix memory leak due to a leaked mmget reference on an error handling
code path that is triggered when attempting to create KFD processes
while a GPU reset is in progress. |

drm/xe: Fix bo leak in intel_fb_bo_framebuffer_init
Add a unreference bo in the error path, to prevent leaking a bo ref.

| BlueZ is a Bluetooth protocol stack for Linux. In affected versions a vulnerability exists in sdp_cstate_alloc_buf which allocates memory which will always be hung in the singly linked list of cstates and will not be freed. This will cause a memory leak over time. The data can be a very large object, which can be caused by an attacker continuously sending sdp packets and this may cause the service of the target device to crash. |
| In the Linux kernel, the following vulnerability has been resolved:
virtio/vsock: Fix accept_queue memory leak
As the final stages of socket destruction may be delayed, it is possible
that virtio_transport_recv_listen() will be called after the accept_queue
has been flushed, but before the SOCK_DONE flag has been set. As a result,
sockets enqueued after the flush would remain unremoved, leading to a
memory leak.

| In the Linux kernel, the following vulnerability has been resolved:
mlxsw: spectrum_ipip: Fix memory leak when changing remote IPv6 address
The device stores IPv6 addresses that are used for encapsulation in
linear memory that is managed by the driver.
Changing the remote address of an ip6gre net device never worked
properly, but since cited commit the following reproducer [1] would
result in a warning [2] and a memory leak [3]. The problem is that the
new remote address is never added by the driver to its hash table (and
therefore the device) and the old address is never removed from it.
Fix by programming the new address when the configuration of the ip6gre
net device changes and removing the old one. If the address did not
change, then the above would result in increasing the reference count of
the address and then decreasing it.
