Intel(R) XMM(TM) 7560 Modem software: Out-of-bounds Read
CVE-2022-26369 is a high-severity out-of-bounds read vulnerability in Intel(R) XMM(TM) 7560 Modem software, with a CVSS 3.1 base score of 8.1 out of 10. It can be exploited from the same local network by an attacker with administrator privileges, without any action from a user. Affected Intel(R) XMM(TM) 7560 Modem software versions: before version M2_7560_R_01.2146.00. The record does not name a fixed version, so check the vendor advisory. There is no confirmed exploitation so far. EPSS estimates a 0.3% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Xmm 7560 Firmware to m2_7560_r_01.2146.00 or a later version.
- Read the advisory on intel.com for workarounds and exact fixed builds.

Official description
Out-of-bounds read in some Intel(R) XMM(TM) 7560 Modem software before version M2_7560_R_01.2146.00 may allow a privileged user to potentially enable escalation of privilege via adjacent access.
Source: the CVE record as published by its numbering authority, via NVD and CVE.org.
The underlying weakness: Out-of-bounds Read
The product reads data past the end, or before the beginning, of the intended buffer.
How developers prevent this class of flaw
- Use a language that provides appropriate memory abstractions.
Timeline
- CVE record published.
- CISA published its SSVC assessment (exploitation: none, automatable: no, technical impact: partial).
- Record last changed materially (score, affected products, status or references).
