Ubuntu 22.10 : Linux kernel (Azure) vulnerabilities (USN-5793-2)

high Nessus Plugin ID 169730

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5793-2 advisory.

 It was discovered that the io_uring subsystem in 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 possibly execute arbitrary code. (CVE-2022-3910)

 It was discovered that a race condition existed in the Android Binder IPC subsystem 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-2022-20421)

 David Leadbeater discovered that the netfilter IRC protocol tracking implementation in the Linux Kernel incorrectly handled certain message payloads in some situations. A remote attacker could possibly use this to cause a denial of service or bypass firewall filtering. (CVE-2022-2663)

 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)

 It was discovered that the Sunplus Ethernet driver in the Linux kernel contained a read-after-free vulnerability. An attacker could possibly use this to expose sensitive information (kernel memory) (CVE-2022-3541)

 It was discovered that a memory leak existed in the Unix domain socket implementation of the Linux kernel.
 A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2022-3543)

 It was discovered that the NILFS2 file system implementation in the Linux kernel did not properly deallocate memory in certain error conditions. An attacker could use this to cause a denial of service (memory exhaustion). (CVE-2022-3544, CVE-2022-3646)

 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 the hugetlb implementation 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) or expose sensitive information (kernel memory). (CVE-2022-3623)

 Khalid Masum discovered that the NILFS2 file system implementation in the Linux kernel did not properly handle certain error conditions, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2022-3649)

 It was discovered that a race condition existed in the MCTP implementation 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-2022-3977)

 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 a race condition existed in the SMSC UFX USB driver implementation in the Linux kernel, leading to a use-after-free vulnerability. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-41849)

 It was discovered that a race condition existed in the Roccat HID 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-2022-41850)

 It was discovered that the USB monitoring (usbmon) component in the Linux kernel did not properly set permissions on memory mapped in to user space processes. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-43750)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
