GHSA-43RV-4Q7X-R3CG
Vulnerability from github – Published: 2026-06-26 21:32 – Updated: 2026-07-08 06:31In the Linux kernel, the following vulnerability has been resolved:
net: mana: Guard mana_remove against double invocation
If PM resume fails (e.g., mana_attach() returns an error), mana_probe() calls mana_remove(), which tears down the device and sets gd->gdma_context = NULL and gd->driver_data = NULL.
However, a failed resume callback does not automatically unbind the driver. When the device is eventually unbound, mana_remove() is invoked a second time. Without a NULL check, it dereferences gc->dev with gc == NULL, causing a kernel panic.
Add an early return if gdma_context or driver_data is NULL so the second invocation is harmless. Move the dev = gc->dev assignment after the guard so it cannot dereference NULL.

There are two issues related to the mapping of pages belonging to other domains: For one, an assertion is wrong there, where the case actually needs handling. A NULL pointer de-reference could result on a release build. This is CVE-2025-58144.
And then the P2M lock isn't held until a page reference was actually obtained (or the attempt to do so has failed). Otherwise the page can not only change type, but even ownership in between, thus allowing domain boundaries to be violated. This is CVE-2025-58145.

GHSA-4473-972Q-596C
Vulnerability from github – Published: 2024-02-26 18:30 – Updated: 2024-04-17 18:31In the Linux kernel, the following vulnerability has been resolved:
thermal: core: Fix NULL pointer dereference in zone registration error path
If device_register() in thermal_zone_device_register_with_trips() returns an error, the tz variable is set to NULL and subsequently dereferenced in kfree(tz->tzp).
Commit adc8749b150c ("thermal/drivers/core: Use put_device() if device_register() fails") added the tz = NULL assignment in question to avoid a possible double-free after dropping the reference to the zone device. However, after commit 4649620d9404 ("thermal: core: Make thermal_zone_device_unregister() return after freeing the zone"), that assignment has become redundant, because dropping the reference to the zone device does not cause the zone object to be freed any more.
Drop it to address the NULL pointer dereference.

The reason is missing input validation in the crcitt_string_array core function for calculating a CRC hash for To tags. (An additional error is present in the check_via_address core function: this function also misses input validation.) This could result in denial of service and potentially the execution of arbitrary code.

xsk: fix usage of multi-buffer BPF helpers for ZC XDP
Currently when packet is shrunk via bpf_xdp_adjust_tail() and memory type is set to MEM_TYPE_XSK_BUFF_POOL, null ptr dereference happens:

This comes from __xdp_return() call with xdp_buff argument passed as NULL which is supposed to be consumed by xsk_buff_free() call.
To address this properly, in ZC case, a node that represents the frag being removed has to be pulled out of xskb_list. Introduce appropriate xsk helpers to do such node operation and use them accordingly within bpf_xdp_adjust_tail().

Mitigation MIT-56
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
Select a programming language that is not susceptible to these issues.
Mitigation
Check the results of all functions that return a value and verify that the value is non-null before acting upon it.
Mitigation
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
Explicitly initialize all variables and other data stores, either during declaration or just before the first usage.
