Description
This security bulletin contains information about 13 secuirty vulnerabilities.
1) Out-of-bounds read (CVE-ID: CVE-2022-2873)
The vulnerability allows a local user to crash the kernel.
The vulnerability exists due to a boundary condition within the Intel iSMT SMBus host controller driver. A local user can send specially crafted data to the I2C_SMBUS IOCTL, trigger an out-of-bounds read error and crash the system.
2) Buffer overflow (CVE-ID: CVE-2022-3545)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within the area_cache_get() function in drivers/net/ethernet/netronome/nfp/nfpcore/nfp_cppcore.c. A local user can trigger memory corruption and execute arbitrary code with elevated privileges.
3) 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.
4) 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.
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) Integer overflow (CVE-ID: CVE-2022-45934)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to integer overflow within the l2cap_config_req() function in net/bluetooth/l2cap_core.c in Linux kernel. A local user can pass specially crafted L2CAP_CONF_REQ packets to the device, trigger an integer overflow and execute arbitrary code with elevated privileges.
7) Use-after-free (CVE-ID: CVE-2022-4696)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in io_uring and the IORING_OP_SPLICE operation. A local user can trigger a use-after-free error and escalate privileges on the system.
8) 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.
9) Integer overflow (CVE-ID: CVE-2023-0179)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to an integer overflow within the nft_payload_copy_vlan() function in Linux kernel Netfilter. A local user can trigger an integer overflow and execute arbitrary code with elevated privileges.
10) 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.
11) 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.
12) Type Confusion (CVE-ID: CVE-2023-23454)
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 cbq_classify() function in net/sched/sch_cbq.c in the Linux kernel. A local user can trigger a type confusion error and crash the kernel.
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.
