Description
This security bulletin contains information about 18 secuirty vulnerabilities.
1) Race condition (CVE-ID: CVE-2022-3623)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition within the follow_page_pte() function in mm/gup.c. A local user can exploit the race and escalate privileges on the system.
2) Use-after-free (CVE-ID: CVE-2022-3625)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the devlink_param_set() and devlink_param_get() function in net/core/devlink.c in IPsec component of Linux kernel. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
3) Race condition (CVE-ID: CVE-2022-3566)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition within the tcp_getsockopt() and tcp_setsockopt() functions in net/ipv4/tcp.c, do_ipv6_setsockopt() function in net/ipv6/ipv6_sockglue.c, and tcp_v6_connect() function in net/ipv6/tcp_ipv6.c in Linux kernel. A local user can exploit the race and escalate privileges on the system.
4) Buffer overflow (CVE-ID: CVE-2022-42721)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a list management error in the mac80211 stack in the Linux kernel when handling BSS. A remote attacker on the local network can send specially crafted WLAN frames to the system, trigger linked list corruption and execute arbitrary code.
5) 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.
6) Use-after-free (CVE-ID: CVE-2022-42703)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the mm/rmap.c in the Linux kernel, related to leaf anon_vma double reuse. A local user can trigger a use-after-free error and crash the kernel.
7) Memory leak (CVE-ID: CVE-2022-3524)
The vulnerability allows a remote attacker to perform DoS attack on the target system.
The vulnerability exists due memory leak within the ipv6_renew_options() function when retrieving a new IPv6 address from a malicious DHCP server. A remote attacker can force the system to leak memory and perform denial of service attack.
8) Race condition (CVE-ID: CVE-2022-3028)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition in the Linux kernel's IP framework for transforming packets (XFRM subsystem) when multiple calls to xfrm_probe_algs occurred simultaneously. A local user can exploit the race and escalate privileges on the system.
9) Out-of-bounds write (CVE-ID: CVE-2021-33655)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error in FBIOPUT_VSCREENINFO IOCTL. A local user can trigger an out-of-bounds write error and execute arbitrary code with elevated privileges.
10) Race condition (CVE-ID: CVE-2022-3567)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition within the inet6_stream_ops() and inet6_dgram_ops() functions. A local user can exploit the race and escalate privileges on the system.
11) Input validation error (CVE-ID: CVE-2022-2663)
The vulnerability allows a remote attacker to bypass firewall rules.
The vulnerability exists due to insufficient validation of user-supplied input in nf_conntrack_irc in Linux kernel. A remote attacker can send unencrypted IRC with nf_conntrack_irc configured and bypass configured firewall rules.
12) Race condition (CVE-ID: CVE-2023-28466)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a race condition caused by a missing lock_sock call within the do_tls_getsockopt() function in net/tls/tls_main.c. A local user can exploit the race and gain unauthorized access to sensitive information and escalate privileges on the system.
13) Use-after-free (CVE-ID: CVE-2023-32233)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in Netfilter nf_tables when processing batch requests. A local user can trigger a use-after-free error and execute arbitrary code with root privileges.
14) 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.
15) Use-after-free (CVE-ID: CVE-2023-1195)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a use-after-free error within the reconn_set_ipaddr_from_hostname() function in fs/cifs/connect.c in Linux kernel. A local user can perform a denial of service (DoS) attack.
16) Use-after-free (CVE-ID: CVE-2023-0461)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error within the Upper Level Protocol (ULP) subsystem in Linux kernel caused by improper handling of sockets entering the LISTEN state in certain protocols. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
17) Buffer overflow (CVE-ID: CVE-2022-3628)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the brcmf_fweh_event_worker() function in drivers/net/wireless/broadcom/brcm80211/brcmfmac/fweh.c. A local user can use a specially crafted device to trigger memory corruption and escalate privileges on the system.
18) Out-of-bounds read (CVE-ID: CVE-2022-1462)
The vulnerability allows a local user to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition within the the Linux kernel’s TeleTYpe subsystem caused by a race condition when using ioctls TIOCSPTLCK and TIOCGPTPEER and TIOCSTI and TCXONC with leakage of memory file. A local user can trigger an out-of-bounds read error and crash the system or read random kernel memory.
