In the Linux kernel, the following vulnerability has been resolved:

net: mvneta: Prevent out of bounds read in mvneta_config_rss()

The pp->indir[0] value comes from the user. It is passed to:

if (cpu_online(pp->rxq_def))

inside the mvneta_percpu_elect() function. It needs bounds checkeding
to ensure that it is not beyond the end of the cpu bitmap.

No CVSS v4.0

Attack Vector Local

Attack Complexity Low

Privileges Required Low

Scope Unchanged

Confidentiality Impact High

Integrity Impact None

Availability Impact High

User Interaction None

No CVSS v3.0

No CVSS v2

This CVE is not in the KEV list.

The EPSS score is 0.00014.

Exploitation none

Automatable no

Technical Impact partial

Default status is the baseline for the product, each version can override it (e.g. patched versions marked unaffected).
