Related CVEs:

  • CVE-2022-4378: A stack overflow flaw was found in the Linux kernel’s SYSCTL subsystem in how a user changes certain kernel parameters and variables. This flaw allows a local user to crash or potentially escalate their privileges on the system.
  • CVE-2023-0266: A use-after-free flaw was found in snd_ctl_elem_read in sound/core/control.c in Advanced Linux Sound Architecture (ALSA) subsystem in the Linux kernel. In this flaw a normal privileged, local attacker may impact the system due to a locking issue in the compat path, leading to a kernel information leak problem.
  • CVE-2023-0386: A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel’s OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allows a local user to escalate their privileges on the system.
