CVE-2022-49348

In the Linux kernel, the following vulnerability has been resolved: ext4: filter out EXT4FCREPLAY from on-disk superblock field sstate The EXT4FCREPLAY bit in sbi-smountstate is used to indicate that we are in the middle of replay the fast commit journal. This was actually a mistake, since the...

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-2022-49343

CVE-2022-49343 (Linux kernel ext4) : A vulnerability in the ext4 filesystem’s h-tree directory structure allows cycles to exist in a directory’s h-tree, which can cause the kernel to access unallocated memory during a node split when traversing blocks. The root cause is that a corrupted filesyste...

CVE-2022-49277

CVE-2022-49277 relates to a memory leak in the JFFS2 code path of the Linux kernel during jffs2_do_mount_fs. The issue arises when jffs2_build_filesystem() returns an error, leading to unfreed resources reported by kmemleak (kmem_cache_alloc_trace and __kmalloc paths). The advisory states the lea...

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...
