CVE-2026-98187

wifi: p54: require a full exp_if record in PDR_INTERFACE_LIST

State: Published
Severity: Not scored

Description

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

wifi: p54: require a full exp_if record in PDR_INTERFACE_LIST

The PDR_INTERFACE_LIST loop only checks that the record start is within the entry before reading an entire struct exp_if from it. A truncated trailing record makes the if_id/variant reads cross the entry boundary into the heap beyond the EEPROM buffer (verified with a KASAN reproducer of the loop). The variant also feeds the synth front-end selection, so this is not only a leak.

Advance only while a full record still fits in the entry.

Scores

The record has no CVSS score.

Weaknesses

The record names no weakness.
