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...

CVE-2026-68166

The CVE-2026-68166 issue in the Linux kernel is addressed by restricting userfaultfd registrations. The fix updates vma_can_userfault() to reject VM_SHADOW_STACK and VM_SPECIAL so that drivers implementing vm_uffd_ops cannot register special VMAs with userfaultfd. VM_SPECIAL’s inclusion of VM_DON...

CVE-2026-68147 fscrypt: Avoid dynamic allocation in fscrypt_get_devices()

In the Linux kernel, the following vulnerability has been resolved: fscrypt: Avoid dynamic allocation in fscryptgetdevices When a blkcryptokey starts being used or is evicted, fs/crypto/ calls fscryptgetdevices to get the filesystem's list of block devices, then iterates over them and calls...

CVE-2026-68147

Summary: CVE-2026-68147 affects the Linux kernel fscrypt subsystem. When a blk_crypto_key is evicted, the code previously allocated a list of block devices on the heap; allocation failures could lead to premature key free and a use-after-free. The fix switches to an on-stack array to enumerate bl...
