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-2026-24491)
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.
3) 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.
4) 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.
5) Heap-based buffer overflow (CVE-ID: CVE-2026-24682)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in audio_formats_free() 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.
6) Use-after-free (CVE-ID: CVE-2026-24676)
The vulnerability allows a remote attacker to compromise vulnerable system.
The vulnerability exists due to a use-after-free error in audio_format_compatible() function. A remote attacker can trick the victim into connecting to a malicious server and execute arbitrary code on the system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
7) Use-after-free (CVE-ID: CVE-2026-24681)
