Description
This security bulletin contains information about 16 secuirty vulnerabilities.
1) Resource exhaustion (CVE-ID: CVE-2021-3669)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to measuring usage of the shared memory does not scale with large shared memory segment counts. A local user can trigger resource exhaustion and perform a denial of service (DoS) attack.
2) Use-after-free (CVE-ID: CVE-2022-3424)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the gru_set_context_option(), gru_fault() and gru_handle_user_call_os() functions in Linux kernel. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
3) Out-of-bounds write (CVE-ID: CVE-2022-36280)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the vmw_kms_cursor_snoo() function in drivers/gpu/vmxgfx/vmxgfx_kms.c in vmwgfx VMWare driver. A local user can trigger an out-of-bounds write and perform a denial of service (DoS) attack.
4) 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.
5) Use-after-free (CVE-ID: CVE-2022-41218)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the dvb_demux_open() and dvb_dmxdev_release() function in drivers/media/dvb-core/dmxdev.c in Linux kernel. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
6) NULL pointer dereference (CVE-ID: CVE-2022-47929)
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 traffic control subsystem in Linux kernel. A local user can pass pass a specially crafted traffic control configuration that is set up with "tc qdisc" and "tc class" commands and perform a denial of service (DoS) attack.
7) Security features bypass (CVE-ID: CVE-2023-0045)
The vulnerability allows a local user to bypass implemented security restrictions.
The vulnerability exists due to Linux kernel does not correctly mitigate SMT attacks. A local user can bypass Spectre-BTI user space mitigations and gain access to sensitive information.
8) Use-after-free (CVE-ID: CVE-2023-0266)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the snd_ctl_elem_read() function in the Linux kernel sound subsystem. A local user can trigger a use-after-free error and execute arbitrary code on the system.
Note, the vulnerability is being actively exploited in the wild.
9) NULL pointer dereference (CVE-ID: CVE-2023-0394)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the rawv6_push_pending_frames() function in net/ipv6/raw.c. A local user can run a specially crafted program on the system and perform a denial of service (DoS) attack.
10) 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.
11) 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.
12) 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.
13) Type Confusion (CVE-ID: CVE-2023-23455)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a type confusion error within the atm_tc_enqueue() function in net/sched/sch_atm.c in the Linux kernel. A local user can trigger a type confusion error and perform a denial of service (DoS) attack.
14) Integer overflow (CVE-ID: CVE-2023-23559)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to integer overflow within the rndis_query_oid() function in drivers/net/wireless/rndis_wlan.c. A local user can trigger an integer overflow and execute arbitrary code with elevated privileges.
15) 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.
16) NULL pointer dereference (CVE-ID: CVE-2023-28328)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error within the az6027 driver in drivers/media/usb/dev-usb/az6027.c in the Linux Kernel. A local user can pass specially crafted data to the application and perform a denial of service (DoS) attack.
