Summary
There are multiple vulnerabilities that can affect IBM Storage Scale System, which could provide weaker than expected security that are now fixed.
Vulnerability Details
CVEID: CVE-2023-52451
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by an error related to access beyond end of drmem array. A local attacker could exploit this vulnerability to cause a denial of service.
CWE: CWE-129: Improper Validation of Array Index
CVSS Source: IBM X-Force
CVSS Base score: 6.2
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2024-41076
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by a flaw in NFSv4. By sending a specially crafted request, a local authenticated attacker could exploit this vulnerability to cause a denial of service.
CWE: CWE-401: Missing Release of Memory after Effective Lifetime
CVSS Source: IBM X-Force
CVSS Base score: 5.5
CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2024-35890
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by a ownership transfer issue if packets are GROed with fraglist. By sending a specially crafted request, a local authenticated attacker could exploit this vulnerability to cause a denial of service condition.
CWE: CWE-1287: Improper Validation of Specified Type of Input
CVSS Source: IBM X-Force
CVSS Base score: 5.5
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2024-42131
DESCRIPTION: In the Linux kernel, the following vulnerability has been resolved:
mm: avoid overflows in dirty throttling logic
The dirty throttling logic is interspersed with assumptions that dirty
limits in PAGE_SIZE units fit into 32-bit (so that various multiplications
fit into 64-bits). If limits end up being larger, we will hit overflows,
possible divisions by 0 etc. Fix these problems by never allowing so
large dirty limits as they have dubious practical value anyway. For
dirty_bytes / dirty_background_bytes interfaces we can just refuse to set
so large limits. For dirty_ratio / dirty_background_ratio it isn't so
simple as the dirty limit is computed from the amount of available memory
which can change due to memory hotplug etc. So when converting dirty
limits from ratios to numbers of pages, we just don't allow the result to
exceed UINT_MAX.
This is root-only triggerable problem which occurs when the operator
sets dirty limits to >16 TB.
CWE: CWE-190: Integer Overflow or Wraparound
CVSS Source: NVD
CVSS Base score: 4.4
CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2024-26783
DESCRIPTION: The Linux Kernel is vulnerable to a denial of service, which is caused by calling wakeup_kswapd() with a wrong zone index. By sending a specially crafted request, a local authenticated attacker could exploit this vulnerability to cause a denial of service.
CWE: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
CVSS Source: IBM X-Force
CVSS Base score: 5.5
CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)
CVEID: CVE-2024-40995
DESCRIPTION: Linux Kernel is vulnerable to a denial of service, caused by an infinite loop in Tcf_idr_check_alloc(). By sending a specially crafted request, a local authenticated attacker could exploit this vulnerability to cause a denial of service.
CWE: CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop')
CVSS Source: IBM X-Force
CVSS Base score: 5.5
CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H)

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
