In the Linux kernel, the following vulnerability has been resolved: ocfs2: fix out-of-bounds write in ocfs2writeendinline KASAN reports a use-after-free write of 4086 bytes in ocfs2writeendinline, called from ocfs2writeendnolock during a copyfilerange splice fallback on a corrupted ocfs2 filesyst...

CVE-2026-43063

A flaw was found in the Linux kernel's XFS filesystem. When recovering attributes, if the xlogrecoveryiget function fails to obtain a valid pointer, a subsequent irele operation attempts to release an invalid memory address. This dangling pointer issue can be exploited by a local attacker,...

CVE-2026-43068

A flaw was found in the Linux kernel's ext4 filesystem. This vulnerability occurs when the system attempts to allocate blocks from a corrupted block group within the ext4 filesystem. An attacker with local access could potentially trigger this condition, leading to delayed block allocation failur...

CVE-2026-43067

A flaw was found in the ext4 filesystem within the Linux kernel. This vulnerability involves an issue where the system incorrectly handles block allocation for indirect mapped files, potentially allowing blocks to be allocated beyond their defined 32-bit limit. This could lead to data corruption ...

CVE-2026-43117

In the Linux kernel, the following vulnerability has been resolved: btrfs: tracepoints: get correct superblock from dentry in event btrfssyncfile If overlay is used on top of btrfs, dentry-dsb translates to overlay's super block and fsid assignment will lead to a crash. Use fileinodefile-isb to...

CVE-2026-43076 ocfs2: validate inline data i_size during inode read

In the Linux kernel, the following vulnerability has been resolved: ocfs2: validate inline data isize during inode read When reading an inode from disk, ocfs2validateinodeblock performs various sanity checks but does not validate the size of inline data. If the filesystem is corrupted, an inode's...
