Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) Unchecked Return Value (CVE-ID: CVE-2022-3108)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to unchecked return value within the kfd_parse_subtype_iolink() function in drivers/gpu/drm/amd/amdkfd/kfd_crat.c. A local user can crash the kernel.
2) Resource management error (CVE-ID: CVE-2022-3903)
The vulnerability allows an attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to an incorrect read request flaw in the Infrared Transceiver USB driver in Linux kernel. An attacker with physical access to the system can starve system resources and perform a denial of service (DoS) attack.
3) NULL pointer dereference (CVE-ID: CVE-2022-4129)
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 Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw to potentially crash the system causing a denial of service.
4) NULL pointer dereference (CVE-ID: CVE-2023-0458)
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 do_prlimit() function. A local user can pass specially crafted data to the system and perform a denial of service (DoS) attack.
5) Buffer overflow (CVE-ID: CVE-2023-1073)
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.
6) Memory leak (CVE-ID: CVE-2023-1074)
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.
7) Use-after-free (CVE-ID: CVE-2023-1281)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in Linux kernel traffic control index filter (tcindex) when the tcf_exts_exec() function is called with the destroyed tcf_ext. A local user attacker can trigger a use-after-free error and execute arbitrary code with elevated privileges.
8) Use-after-free (CVE-ID: CVE-2023-1829)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the tcindex_delete() function. A local user can trigger a use-after-free error and execute arbitrary code with root privileges.
9) Double Free (CVE-ID: CVE-2023-26545)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a double free in net/mpls/af_mpls.c during the renaming of a device. A local user can trigger a double free error and execute arbitrary code with elevated privileges.
