Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-6071-1)
Summary:	The remote host is missing an update for the 'linux-oem-5.17' package(s) announced via the USN-6071-1 advisory.
Description:	Summary: The remote host is missing an update for the 'linux-oem-5.17' package(s) announced via the USN-6071-1 advisory. Vulnerability Insight: It was discovered that the Traffic-Control Index (TCINDEX) implementation in the Linux kernel did not properly perform filter deactivation in some situations. A local attacker could possibly use this to gain elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier has been removed. (CVE-2023-1829) Lin Ma discovered a race condition in the io_uring subsystem in the Linux kernel, leading to a null pointer dereference vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-0468) It was discovered that the OverlayFS implementation in the Linux kernel did not properly handle copy up operation in some conditions. A local attacker could possibly use this to gain elevated privileges. (CVE-2023-0386) David Hildenbrand discovered that a race condition existed in the memory manager of the Linux kernel when handling copy-on-write with shared memory pages. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-2590) It was discovered that the sound subsystem in the Linux kernel contained a race condition in some situations. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-3303) Gwnaun Jung discovered that the SFB packet scheduling implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3586) It was discovered that a race condition existed in the EFI capsule loader driver in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-40307) Zheng Wang and Zhuorao Yang discovered that the RealTek RTL8712U wireless driver in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-4095) It was discovered that the USB core subsystem in the Linux kernel did not properly handle nested reset events. A local attacker with physical access could plug in a specially crafted USB device to cause a denial of service (kernel deadlock). (CVE-2022-4662) It was discovered that a race condition existed in the Xen transport layer implementation for the 9P file system protocol in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (guest crash) or expose sensitive information (guest kernel memory). (CVE-2023-1859) Kyle Zeng discovered that the ATM VC queuing discipline implementation in the Linux kernel contained a type confusion vulnerability in some situations. An attacker could use this to cause a denial of service (system crash). ...
