CVE-2025-38398

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.
