ext4

A subtle memory-management bug deep inside the ext4 remount path—tracked as CVE-2024-0775—can turn routine mount option changes into a kernel-level use-after-free, enabling a local attacker to crash systems or leak kernel memory if left unpatched. Background ext4 is the default filesystem for...

A small, surgical kernel fix landed upstream in mid‑2025 to close a robustness hole in ext4 that could produce a NULL-pointer kernel oops and system crash when the filesystem processed certain orphaned symlink inodes; the patch makes ext4 mark folios dirty only for regular files when running in...

Microsoft’s short product attestation that “Azure Linux includes this open‑source library and is therefore potentially affected” is useful — but it is a product‑scoped inventory statement, not proof that no other Microsoft product or image can include the same vulnerable ext4 code. rview...

A newly recorded Linux kernel vulnerability, tracked as CVE-2025-68261, fixes a subtle race in ext4 by adding i_data_sem protection to ext4_destroy_inline_data_nolock, closing a window where inline-data teardown and b-mapping can collide and trigger a kernel BUG or panic. Background /...

A recently assigned CVE — CVE-2025-68264 — targets the Linux kernel’s ext4 filesystem and documents a race-condition bug that can let stale inline-data size metadata lead to a kernel BUG_ON crash during writes to tiny “inline” files, prompting immediate patching across kernel trees and...

A small but important defensive change landed in the Linux kernel this November to close CVE-2025-40190, an ext4 robustness bug that could let an EA (extended-attribute) inode’s reference count underflow during xattr updates and trigger filesystem errors, orphan churn, and potential...

The Linux kernel received a surgical but important fix for a local filesystem parsing bug: a potential buffer over-read in the ext4 code path that processes superblock mount options, tracked as CVE‑2025‑40198. The change hardens parse_apply_sb_mount_options by treating the superblock field...

The Linux kernel has received a targeted corrective patch for a resource-consumption weakness in the ext4 filesystem — tracked as CVE‑2025‑40179 — that limits the size of orphan files during replay and changes how b-descriptor arrays are allocated to avoid large-order memory allocations...

A small but important kernel hardening landed upstream after syzbot flagged a malformed ext4 inode that set both INLINE_DATA and EXTENTS flags at once — a condition that can bypass extent-tree validation and trigger a BUG_ON in ext4_es_cache_extent, now tracked as CVE-2025-40167. Background ext4...

The Linux kernel CVE-2024-49968 exposes a surprising but practical availability issue in ext4: when the filesystem mount logic is configured to use the DX_HASH_SIPHASH directory-index hash by default, ext4 will refuse to mount filesystems that do not advertise the casefold feature — a mismatch...

The Linux kernel received a targeted fix for a narrowly scoped but potentially disruptive ext4 race where the filesystem could attempt to start a journaling transaction after its journal had begun teardown, tracked as CVE-2025-22113; the patch introduces an explicit mount-level flag to mark the...

Linux 6.16 lands with a broad set of core changes that sharpen the kernel’s performance profile, strengthen confidential computing, and extend hardware coverage—from next‑gen Intel features to modern GPUs and audio DSPs—while also polishing daily driver subsystems such as filesystems...

Hi all, OS Windows 10 Home My PC is dual-boot, Windows 10 Home and Linux "Adobe Photoshop 7.0.exe" is stored on a storage drive in ext4 format but without OS installed. Starting Windows I can connect to this drive but I couldn't start installation of Photoshop. Please advice. Thanks Regards

Hi, I have an SSD which currently has Linux installed on it, and is, I believe, formatted to ext4. I'd like to use this SSD in another computer and clone Windows 7 to it. Do I need to wipe and reformat the SSD, or can I just use it as it is? Thanks.

I am sick of defragmenting really. My largest free space extent is 234.4GB. Why cant Microsoft just improve NTFS to stop fragmentation instead of relying on defragmentation? look at HFS+ and ext4 they prevent fragmentation first!

Hello all, I am attempting to dual boot windows 8 and a linux distro and I fear I may have obfuscated a hdd partition. I ran a bash to find out how my drive partitions are looking: Boot Info Script 0.61 [1 April 2012] ============================= Boot Info Summary...

Hey guys, figured I'd ask some experts if I can save this thing before I do a complete reinstall and lose everything. I was messing around with some software today trying to format an SD card to EXT4, and I ended up with a constant reboot loop and bsod. So I plugged the hard disk into another...

Hi everyone, my hard disk is GPT partitioned for the benefit of Mac OS X and Linux. I recently created a new partition at the end of my hard disk but I can't seem to access it in Windows. Is there a way to get Windows to see the partition? My hard disk currently looks like this: Mac partition...
