Description

This security bulletin contains information about 8 vulnerabilities.


1) Out-of-bounds write (CVE-ID: CVE-2026-22852)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input within the audin_process_formats() function. A remote attacker can trick the victim into connecting to a malicious server, trigger an out-of-bounds write and execute arbitrary code on the target system.

2) Heap-based buffer overflow (CVE-ID: CVE-2026-22854)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


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

The vulnerability exists due to a boundary error in drive_process_irp_read() 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.

3) Use-after-free (CVE-ID: CVE-2026-22856)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to compromise vulnerable system.

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


4) Out-of-bounds read (CVE-ID: CVE-2026-22859)

CWE-ID: CWE-125 - Out-of-bounds read

CVSSv4: CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


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

The vulnerability exists due to a boundary condition within the urb_select_configuration() function. A remote attacker can trick the victim into connecting to a malicious server, trigger an out-of-bounds read error and crash the application.

5) Heap-based buffer overflow (CVE-ID: CVE-2026-23530)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber


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

The vulnerability exists due to a boundary error in planar_decompress_plane_rle. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


6) Heap-based buffer overflow (CVE-ID: CVE-2026-23531)

CWE-ID: CWE-122 - Heap-based Buffer Overflow

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Amber


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

The vulnerability exists due to a boundary error in clear_decompress. A remote attacker can pass specially crafted data to the application, trigger a heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.


7) Heap-based buffer overflow (CVE-ID: CVE-2026-23532)

CWE-ID: CWE-122 - Heap-based Buffer Overflow
