Cairo through 1.18.4, as used in Poppler through 25.08.0, has an "unscaled->face == NULL" assertion failure for _cairo_ft_unscaled_font_fini in cairo-ft-font.c. |
A NULL pointer dereference vulnerability has been identified in the JavaScript library microlight version 0.0.7, a lightweight syntax highlighting library. When processing elements with non-standard CSS color values, the library fails to validate the result of a regular expression match before accessing its properties, leading to an uncaught TypeError and potential application crash. NOTE: this is disputed by multiple parties because there is no common scenario in which an adversary can insert those non-standard values. |
Asterisk is an open-source private branch exchange (PBX). Prior to versions 18.24.3, 20.9.3, and 21.4.3 of Asterisk and versions 18.9-cert12 and 20.7-cert2 of certified-asterisk, if Asterisk attempts to send a SIP request to a URI whose host portion starts with `.1` or `[.1]`, and res_resolver_unbound is loaded, Asterisk will crash with a SEGV. To receive a patch, users should upgrade to one of the following versions: 18.24.3, 20.9.3, 21.4.3, certified-18.9-cert12, certified-20.7-cert2. Two workarounds are available. Disable res_resolver_unbound by setting `noload = res_resolver_unbound.so` in modules.conf, or set `rewrite_contact = yes` on all PJSIP endpoints. NOTE: This may not be appropriate for all Asterisk configurations. |
An access violation vulnerability exists in the DirectComposition functionality win32kbase.sys driver version 10.0.22000.593 as part of Windows 11 version 22000.593 and version 10.0.20348.643 as part of Windows Server 2022 version 20348.643. A specially-crafted set of syscalls can lead to a reboot. An unprivileged user can run specially-crafted code to trigger Denial Of Service. |

A NULL pointer dereference vulnerability has been reported to affect File Station 5. If a remote attacker gains a user account, they can then exploit the vulnerability to launch a denial-of-service (DoS) attack.
We have already fixed the vulnerability in the following version:
File Station 5 5.5.6.4933 and later |
A vulnerability was detected in appneta tcpreplay up to 4.5.1. Impacted is the function tcpedit_post_args of the file /src/tcpedit/parse_args.c. The manipulation results in null pointer dereference. The attack is only possible with local access. The exploit is now public and may be used. Upgrading to version 4.5.2-beta2 is recommended to address this issue. Upgrading the affected component is advised. The vendor explains, that he was "[a]ble to reproduce in 6fcbf03 but not in 4.5.2-beta2". |
A security flaw has been discovered in ckolivas lrzip up to 0.651. This impacts the function __GI_____strtol_l_internal of the file strtol_l.c. Performing manipulation results in null pointer dereference. The attack is only possible with local access. The exploit has been released to the public and may be exploited. |
In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btusb: Fix potential NULL dereference on kmalloc failure
Avoid potential NULL pointer dereference by checking the return value of
kmalloc and handling allocation failure properly. |
Mattermost versions 10.8.x <= 10.8.3, 10.5.x <= 10.5.8, 9.11.x <= 9.11.17, 10.10.x <= 10.10.0, 10.9.x <= 10.9.3 fail to validate import data which allows a system admin to crash the server via the bulk import feature. |
In the Linux kernel, the following vulnerability has been resolved:
ALSA: usb: scarlett2: Fix missing NULL check
scarlett2_input_select_ctl_info() sets up the string arrays allocated
via kasprintf(), but it misses NULL checks, which may lead to NULL
dereference Oops. Let's add the proper NULL check. |
In the Linux kernel, the following vulnerability has been resolved:
wifi: rtw89: avoid NULL dereference when RX problematic packet on unsupported 6 GHz band
With a quite rare chance, RX report might be problematic to make SW think
a packet is received on 6 GHz band even if the chip does not support 6 GHz
band actually. Since SW won't initialize stuffs for unsupported bands, NULL
dereference will happen then in the sequence, rtw89_vif_rx_stats_iter() ->
rtw89_core_cancel_6ghz_probe_tx(). So, add a check to avoid it.
The following is a crash log for this case.

In the Linux kernel, the following vulnerability has been resolved:
can: netlink: can_changelink(): fix NULL pointer deref of struct can_priv::do_set_mode
Andrei Lalaev reported a NULL pointer deref when a CAN device is
restarted from Bus Off and the driver does not implement the struct
can_priv::do_set_mode callback.
There are 2 code path that call struct can_priv::do_set_mode:
- directly by a manual restart from the user space, via
can_changelink()
- delayed automatic restart after bus off (deactivated by default)
To prevent the NULL pointer deference, refuse a manual restart or
configure the automatic restart delay in can_changelink() and report
the error via extack to user space.
As an additional safety measure let can_restart() return an error if
can_priv::do_set_mode is not set instead of dereferencing it
unchecked. |

md_spares_need_change in md_start_sync will call rdev_addable which
protected by rcu_read_lock/rcu_read_unlock. This rcu context will help
protect rdev won't be released, but rdev->mddev will be set to NULL

using READ_ONCE and check does rdev->mddev still alive. |
