GHSA-JW73-X24M-WHQQ

Vulnerability from github – Published: 2025-03-27 18:31 – Updated: 2025-04-14 21:32
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

net: stmmac: enable all safety features by default

In the original implementation of dwmac5 commit 8bf993a5877e ("net: stmmac: Add support for DWMAC5 and implement Safety Features") all safety features were enabled by default.

Later it seems some implementations didn't have support for all the features, so in commit 5ac712dcdfef ("net: stmmac: enable platform specific safety features") the safety_feat_cfg structure was added to the callback and defined for some platforms to selectively enable these safety features.

The problem is that only certain platforms were given that software support. If the automotive safety package bit is set in the hardware features register the safety feature callback is called for the platform, and for platforms that didn't get a safety_feat_cfg defined this results in the following NULL pointer dereference:

[ 7.933303] Call trace: [ 7.935812] dwmac5_safety_feat_config+0x20/0x170 [stmmac] [ 7.941455] __stmmac_open+0x16c/0x474 [stmmac] [ 7.946117] stmmac_open+0x38/0x70 [stmmac] [ 7.950414] __dev_open+0x100/0x1dc [ 7.954006] __dev_change_flags+0x18c/0x204 [ 7.958297] dev_change_flags+0x24/0x6c [ 7.962237] do_setlink+0x2b8/0xfa4 [ 7.965827] __rtnl_newlink+0x4ec/0x840 [ 7.969766] rtnl_newlink+0x50/0x80 [ 7.973353] rtnetlink_rcv_msg+0x12c/0x374 [ 7.977557] netlink_rcv_skb+0x5c/0x130 [ 7.981500] rtnetlink_rcv+0x18/0x2c [ 7.985172] netlink_unicast+0x2e8/0x340 [ 7.989197] netlink_sendmsg+0x1a8/0x420 [ 7.993222] _syssendmsg+0x218/0x280 [ 7.997249] _sys_sendmsg+0xac/0x100 [ 8.001103] __sys_sendmsg+0x84/0xe0 [ 8.004776] __arm64_sys_sendmsg+0x24/0x30 [ 8.008983] invoke_syscall+0x48/0x114 [ 8.012840] el0_svc_common.constprop.0+0xcc/0xec [ 8.017665] do_el0_svc+0x38/0xb0 [ 8.021071] el0_svc+0x2c/0x84 [ 8.024212] el0t_64_sync_handler+0xf4/0x120 [ 8.028598] el0t_64_sync+0x190/0x194

Go back to the original behavior, if the automotive safety package is found to be supported in hardware enable all the features unless safety_feat_cfg is passed in saying this particular platform only supports a subset of the features.

Details

When rendering with headless builds, show an error instead of crashing. Previously GPU_backend_init was called indirectly from DRW_opengl_context_create, a new function is now called from the window manager (GPU_backend_init_once), so it's possible to check if the GPU has a back-end. This also disables the bgl Python module when building WITH_HEADLESS.

GHSA-JX2W-33WW-4XJR

Vulnerability from github – Published: 2025-07-03 09:30 – Updated: 2025-11-20 21:30
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

usb: acpi: Prevent null pointer dereference in usb_acpi_add_usb4_devlink()

As demonstrated by the fix for update_port_device_state, commit 12783c0b9e2c ("usb: core: Prevent null pointer dereference in update_port_device_state"), usb_hub_to_struct_hub() can return NULL in certain scenarios, such as during hub driver unbind or teardown race conditions, even if the underlying usb_device structure exists.

Plus, all other places that call usb_hub_to_struct_hub() in the same file do check for NULL return values.

If usb_hub_to_struct_hub() returns NULL, the subsequent access to hub->ports[udev->portnum - 1] will cause a null pointer dereference.

GHSA-JX3W-WW7J-892Q

Vulnerability from github – Published: 2025-09-15 15:31 – Updated: 2025-12-03 21:31
VLAI
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/msm/mdp5: Add check for kzalloc

As kzalloc may fail and return NULL pointer, it should be better to check the return value in order to avoid the NULL pointer dereference.

Patchwork: https://patchwork.freedesktop.org/patch/514154/

axigen 1.2.6 through 2.0.0b1 does not properly parse login credentials, which allows remote attackers to cause a denial of service (NULL dereference and application crash) via a base64-encoded "*\x00" sequence on the imap port (143/tcp).

Mitigation MIT-56
Implementation

For any pointers that could have been modified or provided from a function that can return NULL, check the pointer for NULL before use. When working with a multithreaded or otherwise asynchronous environment, ensure that proper locking APIs are used to lock before the check, and unlock when it has finished [REF-1484].

Mitigation
Requirements

Select a programming language that is not susceptible to these issues.

Mitigation
Implementation

Check the results of all functions that return a value and verify that the value is non-null before acting upon it.

Mitigation
Architecture and Design

Identify all variables and data stores that receive information from external sources, and apply input validation to make sure that they are only initialized to expected values.

Mitigation
Implementation

Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
