6) NULL pointer dereference (CVE-ID: CVE-2020-11609)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to a NULL pointer dereference error in the stv06xx subsystem in the "drivers/media/usb/gspca/stv06xx/stv06xx.c" and "drivers/media/usb/gspca/stv06xx/stv06xx_pb0100.c" files. A remote authenticated attacker can perform a denial of service (DoS) attack.
7) NULL pointer dereference (CVE-ID: CVE-2020-11668)
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 drivers/media/usb/gspca/xirlink_cit.c in Xirlink camera USB driver. A local user can pass specially crafted data to the driver and perform a denial of service (DoS) attack.
8) Buffer overflow (CVE-ID: CVE-2020-12465)
The vulnerability allows a local privileged user to execute arbitrary code.
An array overflow was discovered in mt76_add_fragment in drivers/net/wireless/mediatek/mt76/dma.c in the Linux kernel before 5.5.10, aka CID-b102f0c522cf. An oversized packet with too many rx fragments can corrupt memory of adjacent pages.
9) Buffer overflow (CVE-ID: CVE-2021-4157)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the Linux kernel NFS subsystem. A remote attacker can create a specially crafted data and crash the system or escalate privileges on the system
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
10) Use-after-free (CVE-ID: CVE-2021-4202)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in the nci_request() function in net/nfc/nci/core.c in NFC Controller Interface (NCI) in the Linux kernel. A local user can cause a data race problem while the device is getting removed and escalate privileges on the system.
11) Use-after-free (CVE-ID: CVE-2021-4203)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in sock_getsockopt() function in net/core/sock.c due to SO_PEERCRED and SO_PEERGROUPS race with listen() function (and connect() function) in the Linux kernel. A local user can exploit the use-after-free error and crash the system or escalate privileges on the system.
12) Use-after-free (CVE-ID: CVE-2021-45868)
The vulnerability allows a local user to perform a denial-of-service attack.
The vulnerability exists due to fs/quota/quota_tree.c does not validate the block number in the quota tree (on disk). A local user can trigger use-after-free error and perform a denial-of-service attack.
13) Buffer overflow (CVE-ID: CVE-2022-0330)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a random memory access flaw caused by a missing TLB flush in Linux kernel GPU i915 kernel driver functionality. A local user can execute arbitrary code on the system with elevated privileges.
14) Stack-based buffer overflow (CVE-ID: CVE-2022-0435)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error in the Linux kernel networking module for the Transparent Inter-Process Communication (TIPC) protocol. A remote unauthenticated attacker can send specially crafted traffic to the system, trigger a stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system but requires that the TIPC bearer is set up.
15) NULL pointer dereference (CVE-ID: CVE-2022-0617)
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 UDF file system functionality. A local user can supply a malicious UDF image to the udf_file_write_iter() function and perform a denial of service (DoS) attack.
16) Use of uninitialized resource (CVE-ID: CVE-2022-0847)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to usage of an uninitialized resources. A local user can overwrite arbitrary file in the page cache, even if the file is read-only, and execute arbitrary code on the system with elevated privileges.
The vulnerability was dubbed Dirty Pipe.
17) Heap-based buffer overflow (CVE-ID: CVE-2022-27666)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a boundary error within IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c in Linux kernel. A local unprivileged user can pass specially crafted data to the system, trigger a heap-based buffer overflow and execute arbitrary code with elevated privileges.
18) Information disclosure (CVE-ID: CVE-2022-1353)
The vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application in the pfkey_register function in net/key/af_key.c in the Linux kernel. A local user can gain unauthorized access to kernel memory, leading to a system crash or a leak of internal kernel information.
19) Use-after-free (CVE-ID: CVE-2022-1419)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a use-after-free error in vgem_gem_dumb_create() function in Linux kernel. A local user can trigger a use-after-free error and execute arbitrary code with elevated privileges.
20) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2022-22942)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to an error in the vmwgfx driver in Linux kernel. A local unprivileged user can gain access to files opened by other processes on the system through a dangling 'file' pointer.
Exploiting this vulnerability requires an attacker to have access to either /dev/dri/card0 or /dev/dri/rendererD128 and be able to issue an ioctl() on the resulting file descriptor.
21) Improper update of reference count (CVE-ID: CVE-2022-29581)
The vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to improper update of reference count in net/sched in Linux kernel. A local user can execute arbitrary code with root privileges.
