Security Vulnerabilities - CVEs Published In April 2025
In the Linux kernel, the following vulnerability has been resolved:
regulator: dummy: force synchronous probing
Sometimes I get a NULL pointer dereference at boot time in kobject_get()
with the following call stack:
anatop_regulator_probe()
devm_regulator_register()
regulator_register()
regulator_resolve_supply()
kobject_get()
By placing some extra BUG_ON() statements I could verify that this is
raised because probing of the 'dummy' regulator driver is not completed
('dummy_regulator_rdev' is still NULL).
In the JTAG debugger I can see that dummy_regulator_probe() and
anatop_regulator_probe() can be run by different kernel threads
(kworker/u4:*). I haven't further investigated whether this can be
changed or if there are other possibilities to force synchronization
between these two probe routines. On the other hand I don't expect much
boot time penalty by probing the 'dummy' regulator synchronously.

In the Linux kernel, the following vulnerability has been resolved:
RDMA/hns: Fix soft lockup during bt pages loop
Driver runs a for-loop when allocating bt pages and mapping them with
buffer pages. When a large buffer (e.g. MR over 100GB) is being allocated,
it may require a considerable loop count. This will lead to soft lockup:
watchdog: BUG: soft lockup - CPU#27 stuck for 22s!
...
Call trace:
hem_list_alloc_mid_bt+0x124/0x394 [hns_roce_hw_v2]

hns_roce_reg_user_mr+0x108/0x1c0 [hns_roce_hw_v2]
ib_uverbs_reg_mr+0x120/0x2bc
Add a cond_resched() to fix soft lockup during these loops. In order not
to affect the allocation performance of normal-size buffer, set the loop
count of a 100GB MR as the threshold to call cond_resched().

A vulnerability has been identified in SENTRON 7KT PAC1260 Data Manager (All versions). Affected devices contain hardcoded credentials for remote access to the device operating system with root privileges. This could allow unauthenticated remote attackers to gain full access to a device, if they are in possession of these credentials and if the ssh service is enabled (e.g., by exploitation of CVE-2024-41793).

A vulnerability has been identified in SENTRON 7KT PAC1260 Data Manager (All versions). The web interface of affected devices is vulnerable to Cross-Site Request Forgery (CSRF) attacks. This could allow an unauthenticated attacker to change arbitrary device settings by tricking a legitimate device administrator to click on a malicious link.

A vulnerability has been identified in SENTRON 7KT PAC1260 Data Manager (All versions). The web interface of affected devices allows to change the login password without knowing the current password. In combination with a prepared CSRF attack (CVE-2024-41795) an unauthenticated attacker could be able to set the password to an attacker-controlled value.

A vulnerability has been identified in SENTRON 7KT PAC1260 Data Manager (All versions). The web interface of affected devices does not authenticate report creation requests. This could allow an unauthenticated remote attacker to read or clear the log files on the device, reset the device or set the date and time.
