Description

This security bulletin contains information about 6 vulnerabilities.


1) Buffer overflow (CVE-ID: CVE-2023-1073)

CWE-ID: CWE-119 - Memory corruption

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


The vulnerability allows an attacker to compromise the affected system.

The vulnerability exists due to a boundary error in the Linux kernel human interface device (HID) subsystem. An attacker with physical access to the system can insert in a specific way malicious USB device, trigger memory corruption and execute arbitrary code.


2) Memory leak (CVE-ID: CVE-2023-1074)

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

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


The vulnerability allows a local user to perform DoS attack on the target system.

The vulnerability exists due memory leak in Linux kernel Stream Control Transmission Protocol. A local user can start a malicious network service and then connect to remotely, forcing the kernel to leak memory.


3) NULL pointer dereference (CVE-ID: CVE-2023-1095)

CWE-ID: CWE-476 - NULL Pointer Dereference

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


The vulnerability allows a local user to perform a denial of service (DoS) attack.

The vulnerability exists due to a NULL pointer dereference error in the nf_tables_updtable() function within the netfilter subsystem. A local user can perform a denial of service (DoS) attack.


4) Use-after-free (CVE-ID: CVE-2023-3141)

CWE-ID: CWE-416 - Use After Free

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


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within the r592_remove() function of drivers/memstick/host/r592.c in media access in the Linux kernel. A local user can trigger a use-after-free error and escalate privileges on the system.


5) Out-of-bounds read (CVE-ID: CVE-2023-3268)

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

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


The vulnerability allows a local user to gain access to potentially sensitive information.

The vulnerability exists due to a boundary condition within the relay_file_read_start_pos() function in kernel/relay.c in the relayfs. A local user can trigger an out-of-bounds read error and read contents of memory on the system or crash the kernel.


6) Use-after-free (CVE-ID: CVE-2023-35829)

CWE-ID: CWE-416 - Use After Free

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


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a use-after-free error within the rkvdec_remove() function in drivers/staging/media/rkvdec/rkvdec.c. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
