CVE-2026-92501

CVE-2026-92501 is a race condition in the Linux kernel's ext4 filesystem, affecting the direct I/O (DIO) to buffered write fallback path in ext4_dio_write_iter(). On no-extent inodes (e.g., ext3), DIO writes to holes cause a fallback to buffered I/O. An unprotected window exists between ext4_buff...

EUVD-2026-82051

In the Linux kernel, the following vulnerability has been resolved: md/bitmap: resume array on backlogstore error path backlogstore suspends the array before checking whether a write-mostly device exists. If no such device exists, the error path only unlocks reconfigmutex and leaves the array...

CVE-2026-90315 PCI/sysfs: Add lockdown checks to legacy I/O and memory handlers

In the Linux kernel, the following vulnerability has been resolved: PCI/sysfs: Add lockdown checks to legacy I/O and memory handlers Currently, the legacy I/O and memory sysfs handlers do not check securitylockeddownLOCKDOWNPCIACCESS, leaving the legacyio and legacymem files unprotected when the...

CVE-2026-90315

CVE-2026-90315 affects the Linux kernel's PCI/sysfs subsystem. The legacy I/O and memory handlers (pci_write_legacy_io() , pci_mmap_legacy_mem() , pci_mmap_legacy_io() ) fail to check security_locked_down(LOCKDOWN_PCI_ACCESS) , leaving the legacy_io and legacy_mem sysfs files unprotected during k...

CVE-2026-90275 md/raid1: don't set array_frozen in raid1_takeover()

In the Linux kernel, the following vulnerability has been resolved: md/raid1: don't set arrayfrozen in raid1takeover raid1takeover sets conf-arrayfrozen = 1 on the newly-allocated r1conf and nothing ever clears it, so every I/O to the array stalls permanently once waitbarrier sees it stuck at 1...

CVE-2026-90227 nvme/ioctl: check SUBMIT_IO with nvme_cmd_allowed()

In the Linux kernel, the following vulnerability has been resolved: nvme/ioctl: check SUBMITIO with nvmecmdallowed Unlike IOCMD / IO64CMD, NVMEIOCTLSUBMITIO never calls nvmecmdallowed. Unprivileged callers can thus issue I/O on a partition device or write through a read-only file descriptor. Pass...

CVE-2026-90227

This is a local privilege escalation vulnerability in the Linux kernel's nvme/ioctl subsystem. The root cause is that NVME_IOCTL_SUBMIT_IO never calls nvme_cmd_allowed() , unlike the IO_CMD and IO64_CMD ioctl paths. As a result, unprivileged local callers can issue I/O on a partition device or wr...

github.com/cri-o/cri-o: Fix Bypass for CVE-2022-4318 — /etc/passwd Injection via HOME env

A flaw was found in CRI-O. The fix for a previous vulnerability CVE-2022-4318 was incorrect, allowing it to be bypassed. An attacker capable of setting environment variables on a container can inject a newline character into the HOME environment variable. This issue allows the addition of arbitra...
