Ubuntu 23.04 : Linux kernel vulnerabilities (USN-6283-1)

critical Nessus Plugin ID 179705

Language:

Synopsis

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

Description

The remote Ubuntu 23.04 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6283-1 advisory.

 Ruihan Li discovered that the bluetooth subsystem in the Linux kernel did not properly perform permissions checks when handling HCI sockets. A physically proximate attacker could use this to cause a denial of service (bluetooth communication). (CVE-2023-2002)

 Zheng Zhang discovered that the device-mapper implementation in the Linux kernel did not properly handle locking during table_clear() operations. A local attacker could use this to cause a denial of service (kernel deadlock). (CVE-2023-2269)

 It was discovered that the Ricoh R5C592 MemoryStick card reader driver in the Linux kernel contained a race condition during module unload, 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-2023-3141)

 Quentin Minster discovered that the KSMBD implementation in the Linux kernel did not properly validate pointers in some situations, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a denial of service (system crash). (CVE-2023-32248)

 Quentin Minster discovered that a race condition existed in the KSMBD implementation in the Linux kernel, leading to a use-after-free vulnerability. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-32254)

 It was discovered that the kernel->user space relay implementation in the Linux kernel did not properly perform certain buffer calculations, leading to an out-of-bounds read vulnerability. A local attacker could use this to cause a denial of service (system crash) or expose sensitive information (kernel memory). (CVE-2023-3268)

 It was discovered that the QCOM CPUFreq HW driver in the Linux kernel on ARM processors did not properly handle device unbind. A local attacker could use this to cause a denial of service (system crash).
 (CVE-2023-3312)

 It was discovered that the MediaTek MT7921E (PCIe) WiFi driver in the Linux kernel contained a use-after- free vulnerability when querying the firmware features of the device. A local attacker could use this to cause a denial of service (system crash). (CVE-2023-3317)

 It was discovered that the video4linux driver for Philips based TV cards in the Linux kernel contained a race condition during device removal, 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-2023-35823)

 It was discovered that the SDMC DM1105 PCI device driver in the Linux kernel contained a race condition during device removal, 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-2023-35824)

 It was discovered that the Allwinner Cedar video engine driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35826)

 It was discovered that the Renesas USB controller driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35828)

 It was discovered that the Rockchip Video Decoder IP driver in the Linux kernel contained a race condition during device removal, leading to a use- after-free vulnerability. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-35829)

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.
