Description

This security bulletin contains information about 12 secuirty vulnerabilities.


1) NULL pointer dereference (CVE-ID: CVE-2026-23948)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in rdp_write_logon_info_v2(). A remote attacker can trick the victim into connecting to a malicious server and crash the application.


2) Use-after-free (CVE-ID: CVE-2026-24680)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in update_pointer_new(SDL) function. A remote attacker can trick the victim into connecting to a malicious server and execute arbitrary code on the system.

3) Use-after-free (CVE-ID: CVE-2026-24491)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in video_timer() function. A remote attacker can trick the victim into connecting to a malicious server and execute arbitrary code on the system.

4) Use-after-free (CVE-ID: CVE-2026-24675)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in urb_select_interface() function. A remote attacker can trick the victim into connecting to a malicious server and execute arbitrary code on the system.

5) Use-after-free (CVE-ID: CVE-2026-24681)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in urb_bulk_transfer_cb() function. A remote attacker can trick the victim into connecting to a malicious server and execute arbitrary code on the system.

6) Heap-based buffer overflow (CVE-ID: CVE-2026-24679)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in urb_select_interface() function. A remote attacker can trick the victim into connecting to a malicious server, trigger a heap-based buffer overflow and execute arbitrary code on the target system.


7) Use-after-free (CVE-ID: CVE-2026-24684)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in play_thread() function. A remote attacker can trick the victim into connecting to a malicious server and execute arbitrary code on the system.

8) Use-after-free (CVE-ID: CVE-2026-24678)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in cam_v4l_stream_capture_thread() function. A remote attacker can trick the victim into connecting to a malicious server and execute arbitrary code on the system.

9) Heap-based buffer overflow (CVE-ID: CVE-2026-24677)

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error in ecam_encoder_compress_h264() function. A remote attacker can trick the victim into connecting to a malicious server, trigger a heap-based buffer overflow and execute arbitrary code on the target system.
