SUSE SLES15 Security Update : the Linux RT Kernel (SUSE-SU-2022:0543-1)

high Nessus Plugin ID 158225

Language:

Synopsis

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

Description

The remote SUSE Linux SLES15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0543-1 advisory.

- The vgacon subsystem in the Linux kernel before 5.8.10 mishandles software scrollback. There is a vgacon_scrolldelta out-of-bounds read, aka CID-973c096f6a85. (CVE-2020-28097)

- A double free bug in packet_set_ring() in net/packet/af_packet.c can be exploited by a local user through crafted syscalls to escalate privileges or deny service. We recommend upgrading kernel past the effected versions or rebuilding past ec6af094ea28f0f2dda1a6a33b14cd57e36a9755 (CVE-2021-22600)

- In gadget_dev_desc_UDC_show of configfs.c, there is a possible disclosure of kernel heap memory due to a race condition. This could lead to local information disclosure with System execution privileges needed.
User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
A-160822094References: Upstream kernel (CVE-2021-39648)

- In ufshcd_eh_device_reset_handler of ufshcd.c, there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure with System execution privileges needed.
User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID:
A-194696049References: Upstream kernel (CVE-2021-39657)

- In various setup methods of the USB gadget subsystem, there is a possible out of bounds write due to an incorrect flag check. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-210292376References: Upstream kernel (CVE-2021-39685)

- pep_sock_accept in net/phonet/pep.c in the Linux kernel through 5.15.8 has a refcount leak.
(CVE-2021-45095)

- A flaw was found in the Linux kernel. A null pointer dereference in bond_ipsec_add_sa() may lead to local denial of service. (CVE-2022-0286)

- A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or escalate their privileges on the system. (CVE-2022-0330)

- kernel: failing usercopy allows for use-after-free exploitation (CVE-2022-22942)

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