Security Bulletin: Vulnerabilities in the Linux kernel affect IBM SAN Volume Controller, IBM Storwize, IBM Spectrum Virtualize and IBM FlashSystem V9000 products

Description

## Summary Multiple vulnerabilities in the Linux kernel could allow an authenticated attacker to obtain sensitive information. ## Vulnerability Details **CVEID: **[CVE-2020-10732](<https://vulners.com/cve/CVE-2020-10732>) **DESCRIPTION: **Linux Kernel could allow a local authenticated attacker to obtain sensitive information, caused by a flaw in the implementation of Userspace core dumps. By sending a specially crafted request, an attacker could exploit this vulnerability to obtain sensitive information or cause a program to crash. CVSS Base score: 3.3 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/181554](<https://exchange.xforce.ibmcloud.com/vulnerabilities/181554>) for the current score. CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N) **CVEID: **[CVE-2020-10774](<https://vulners.com/cve/CVE-2020-10774>) **DESCRIPTION: **Linux Kernel could allow a local authenticated attacker to obtain sensitive information, caused by a flaw in the sysctl subsystem. By reading the file /proc/sys/kernel/rh_features, an attacker could exploit this vulnerability to obtain uninitialized values from the kernel memory. CVSS Base score: 5.5 CVSS Temporal Score: See: [ https://exchange.xforce.ibmcloud.com/vulnerabilities/192481](<https://exchange.xforce.ibmcloud.com/vulnerabilities/192481>) for the current score.
