CVE-2022-49343 ext4: avoid cycles in directory h-tree

In the Linux kernel, the following vulnerability has been resolved: ext4: avoid cycles in directory h-tree A maliciously corrupted filesystem can contain cycles in the h-tree stored inside a directory. That can easily lead to the kernel corrupting tree nodes that were already verified under its...

CVE-2022-49174 ext4: fix ext4_mb_mark_bb() with flex_bg with fast_commit

In the Linux kernel, the following vulnerability has been resolved: ext4: fix ext4mbmarkbb with flexbg with fastcommit In case of flexbg feature which is by default enabled, extents for any given inode might span across blocks from two different block group. ext4mbmarkbb only reads the bufferhead...

CVE-2022-49174

CVE-2022-49174 affects the Linux kernel ext4 filesystem, specifically the ext4_mb_mark_bb() logic when flex_bg (default enabled) and fast_commit are used. The issue occurs when an inode’s extents span block groups and ext4_mb_mark_bb() reads the starting block group’s bitmap only once; it does no...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from ext4 not properly handling reserved GDT blocks when resizing the filesystem, which could lead to null pointer...

The vulnerability of the ext4_mb_find_good_group_avg_frag_lists() function in the ext4 file system of the Linux operating system allows a attacker to cause a service failure.

The vulnerability of the ext4mbfindgoodgroupavgfraglists function in the ext4 file system of the Linux operating system is related to read errors beyond the memory boundary. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2024-57262

CVE-2024-57262 affects barebox prior to 2025.01.0. The flaw is in ext4fs_read_symlink, where a zalloc overflow (adding one to an le32) on a crafted ext4 filesystem with inode size 0xffffffff causes a malloc(0) and a subsequent memory overwrite. This yields a high-severity impact (memory corruptio...
