In the Linux kernel, the following vulnerability has been resolved: erofs: fix incorrect early exits in volume label handling Crafted EROFS images containing valid volume labels can trigger incorrect early returns, leading to folio reference leaks. However, this does not cause system crashes or...

CVE-2025-71271

CVE-2025-71271 affects the Linux kernel hfsplus filesystem driver. A bug introduced during the move to the new mount API could leak filesystem-specific data (sb->s_fs_info) if setup_bdev_super() fails after a new superblock is allocated but before hfsplus_fill_super() takes ownership. The leak...

CVE-2026-43075

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 ...
