Description
This security bulletin contains information about 5 vulnerabilities.
1) Heap-based buffer overflow (CVE-ID: CVE-2026-22855)
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 smartcard_unpack_set_attrib_call() 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.
2) Out-of-bounds write (CVE-ID: CVE-2026-22853)
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 ndr_read_uint8Array() 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.
3) Out-of-bounds read (CVE-ID: CVE-2026-22858)
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 crypto_base64_decode() 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.
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) Use-after-free (CVE-ID: CVE-2026-24678)
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 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.
