Description
This security bulletin contains information about 9 secuirty vulnerabilities.
1) NULL pointer dereference (CVE-ID: CVE-2023-3772)
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 xfrm_update_ae_params() function in the IP framework for transforming packets (XFRM subsystem). A local user with CAP_NET_ADMIN privileges can perform a denial of service (DoS) attack.
2) Buffer overflow (CVE-ID: CVE-2023-38409)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the set_con2fb_map() function in drivers/video/fbdev/core/fbcon.c. A local user can trigger memory corruption and perform a denial of service (DoS) attack.
3) Use-after-free (CVE-ID: CVE-2023-3567)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the vc_screen() function in vcs_read in drivers/tty/vt/vc_screen.c. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
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) Type Confusion (CVE-ID: CVE-2023-1075)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a type confusion error within the tls_is_tx_ready() function in the net/tls stack of the Linux Kernel. A local user can trigger a type confusion error and execute arbitrary code with elevated privileges.
6) Use-after-free (CVE-ID: CVE-2023-4622)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the unix_stream_sendpage() function in af_unix component. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
7) 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.
8) Use-after-free (CVE-ID: CVE-2023-4128)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within net/sched/cls_fw.c in classifiers (cls_fw, cls_u32, and cls_route) in the Linux Kernel. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
9) Out-of-bounds write (CVE-ID: CVE-2023-42753)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in the netfilter subsystem in Linux kernel. A local user can trigger an out-of-bounds write and execute arbitrary code with elevated privileges.
