Scientific Linux Security Update : kernel on SL7.x x86_64 (2022:0620)

high Nessus Plugin ID 158330

Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

The remote Scientific Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the SLSA-2022:0620-1 advisory.

- kernel: use after free in eventpoll.c may lead to escalation of privilege (CVE-2020-0466)

- kernel: Use After Free in unix_gc() which could result in a local privilege escalation (CVE-2021-0920)

- kernel: xfs: raw block device data leak in XFS_IOC_ALLOCSP IOCTL (CVE-2021-4155)

- kernel: possible privileges escalation due to missing TLB flush (CVE-2022-0330)

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

- kernel: out of bounds write in hid-multitouch.c may lead to escalation of privilege (CVE-2020-0465)

- kernel: double free in bluetooth subsystem when the HCI device initialization fails (CVE-2021-3564)

- kernel: use-after-free in function hci_sock_bound_ioctl() (CVE-2021-3573)

- kernel: possible use-after-free in bluetooth module (CVE-2021-3752)

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

Solution
