CVE-2026-68184

A flaw was found in the Linux kernel's CD-ROM cdrom driver. When handling the CDROMVOLCTRL command, the mmcioctlcdromvolume function can perform an incorrect calculation of buffer length after a pointer adjustment. This leads to a stack out-of-bounds read, where 8 bytes of data beyond the intende...

CVE-2026-68184

The CVE-2026-68184 issue affects the Linux kernel CD-ROM code, specifically mmc_ioctl_cdrom_volume for CDROMVOLCTRL. A 32-byte stack buffer is used to read the audio control mode page (buflen 24, then extended if a block descriptor is present). The function later builds a MODE SELECT payload by m...

Astra Linux – Vulnerability in Qemu

An “off-by-one” error was detected in the SCSI device emulation in QEMU. This error could occur during the processing of MODE SELECT commands in modesensepage, if the ‘page’ argument is set to MODEPAGEALLS 0x3f. A malicious guest could exploit this flaw to potentially cause QEMU to crash, resulti...
