Category:	Ubuntu Local Security Checks
Title:	Ubuntu: Security Advisory (USN-5442-2)
Summary:	The remote host is missing an update for the 'linux-bluefield, linux-gcp-5.4, linux-gkeop, linux-gkeop-5.4, linux-ibm-5.4, linux-oracle, linux-oracle-5.4, linux-raspi, linux-raspi-5.4' package(s) announced via the USN-5442-2 advisory.
Description:	Summary: The remote host is missing an update for the 'linux-bluefield, linux-gcp-5.4, linux-gkeop, linux-gkeop-5.4, linux-ibm-5.4, linux-oracle, linux-oracle-5.4, linux-raspi, linux-raspi-5.4' package(s) announced via the USN-5442-2 advisory. Vulnerability Insight: Kyle Zeng discovered that the Network Queuing and Scheduling subsystem of the Linux kernel did not properly perform reference counting in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-29581) Bing-Jhong Billy Jheng discovered that the io_uring subsystem in the Linux kernel contained in integer overflow. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-1116) Jann Horn discovered that the Linux kernel did not properly enforce seccomp restrictions in some situations. A local attacker could use this to bypass intended seccomp sandbox restrictions. (CVE-2022-30594) Affected Software/OS: 'linux-bluefield, linux-gcp-5.4, linux-gkeop, linux-gkeop-5.4, linux-ibm-5.4, linux-oracle, linux-oracle-5.4, linux-raspi, linux-raspi-5.4' package(s) on Ubuntu 18.04, Ubuntu 20.04. Solution: Please install the updated package(s). CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
