CVE-2026-46192
5.5 · MEDIUMOverview
CVE-2026-46192 is a medium-severity vulnerability affecting linux linux_kernel. It was published on May 28, 2026 and has a CVSS 3.1 base score of 5.5 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. 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: microchip-core-qspi: don't attempt to transmit during emulated read-only dual/quad operations
The core will deal with reads by creating clock cycles itself, there's
no need to generate clock cycles by transmitting garbage data at the
driver level. Further, transmitting garbage data just bricks the transfer
since QSPI doesn't have a dedicated master-out line like MOSI in regular
SPI. I'm not entirely sure if the transfer is bricked because of the
garbage data being transmitted on the bus or because the core loses
track of whether it is supposed to be sending or receiving data.
Remediation
Check the references section for vendor advisories and patches from linux. Update linux_kernel to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
