Overview

CVE-2025-38398 is a high-severity vulnerability. It was published on July 25, 2025 and has a CVSS 3.1 base score of 7.8 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.8, rated HIGH. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical description

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

spi: spi-qpic-snand: reallocate BAM transactions

Using the mtd_nandbiterrs module for testing the driver occasionally

results in weird things like below.

1. swiotlb mapping fails with the following message:

[ 85.926216] qcom_snand 79b0000.spi: swiotlb buffer is full (sz: 4294967294 bytes), total 512 (slots), used 0 (slots)

[ 85.932937] qcom_snand 79b0000.spi: failure in mapping desc

[ 87.999314] qcom_snand 79b0000.spi: failure to write raw page

[ 87.999352] mtd_nandbiterrs: error: write_oob failed (-110)

Rebooting the board after this causes a panic due to a NULL pointer

dereference.

2. If the swiotlb mapping does not fail, rebooting the board may result

in a different panic due to a bad spinlock magic:

[ 256.104459] BUG: spinlock bad magic on CPU#3, procd/2241

[ 256.104488] Unable to handle kernel paging request at virtual address ffffffff0000049b
