Security fix for CVE-2023-4692 Security fix for CVE-2023-4693 Fri Mar 08 2024 Nicolas Frayer - 2.06-118 - fs/xfs: Handle non-continuous data blocks ...

CVE-2024-26973

In the Linux kernel, the following vulnerability has been resolved: fat: fix uninitialized field in nostale filehandles When fatencodefhnostale encodes file handle without a parent it stores only first 10 bytes of the file handle. However the length of the file handle must be a multiple of 4 so t...

buildah: full container escape at build time

A flaw was found in Buildah and subsequently Podman Build which allows containers to mount arbitrary locations on the host filesystem into build containers. A malicious Containerfile can use a dummy image with a symbolic link to the root filesystem as a mount source and cause the mount operation ...

UBUNTU-CVE-2024-27032

In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to avoid potential panic during recovery During recovery, if FAULTBLOCK is on, it is possible that f2fsreservenewblock will return -ENOSPC during recovery, then it may trigger panic. Also, if fault injection rate is 1 a...

UBUNTU-CVE-2024-27069

In the Linux kernel, the following vulnerability has been resolved: ovl: relax WARNON in ovlverifyarea syzbot hit an assertion in copy up data loop which looks like it is the result of a lower file whose size is being changed underneath overlayfs. This type of use case is documented to cause...

grub2: grub2-set-bootflag can be abused by local (pseudo-)users

A flaw was found in the grub2-set-bootflag utility of grub2. After the fix of CVE-2019-14865, grub2-set-bootflag will create a temporary file with the new grubenv content and rename it to the original grubenv file. If the program is killed before the rename operation, the temporary file will not ...

golang: io/fs: stack exhaustion in Glob

A flaw was found in the golang standard library, io/fs. Calling Glob on a path that contains a large number of path separators can cause a panic issue due to stack exhaustion. This could allow an attacker to impact availability...

exfatprogs: exfatprogs allows out-of-bounds memory access

A flaw was found in Exfatprogs, a userspace utility that contains all of the standard utilities for creating, fixing, and debugging the exfat filesystem in the linux system.This issue may allow out-of-bounds memory access such as in readfiledentryset. To exploit this vulnerability, the attacker...

kernel: ovl: fix tmpfile leak

In the Linux kernel, the following vulnerability has been resolved: ovl: fix tmpfile leak Missed an error cleanup...

kernel: ext4: add bounds checking in get_max_inline_xattr_value_size()

In the Linux kernel, the following vulnerability has been resolved: ext4: add bounds checking in getmaxinlinexattrvaluesize Normally the extended attributes in the inode body would have been checked when the inode is first opened, but if someone is writing to the block device while the file syste...

kernel: CIFS Filesystem Decryption Improper Input Validation Remote Code Execution Vulnerability in function receive_encrypted_standard of client

An out-of-bounds memory read flaw was found in receiveencryptedstandard in fs/smb/client/smb2ops.c in the SMB Client sub-component in the Linux Kernel. This issue occurs due to integer underflow on the memcpy length, leading to a denial of service...

kernel: ext4: init quota for 'old.inode' in 'ext4_rename'

In the Linux kernel, the following vulnerability has been resolved: ext4: init quota for 'old.inode' in 'ext4rename' Syzbot found the following issue: ext4parseparam: swantextraisize=128 ext4inodeinfoinit: swantextraisize=32 ext4rename: old.inode=ffff88823869a2c8 old.dir=ffff888238699828...

kernel: ext4: fix rbtree traversal bug in ext4_mb_use_preallocated

A flaw was identified in the ext4 filesystem’s block preallocation allocator in the Linux kernel. During allocation, the code traverses an rbtree of per-inode preallocations.Concurrently, the helper ext4mbdiscardgrouppreallocation can mark PAs as deleted, which may cause a naive rbtree traversal ...

kernel: ext4: fix use-after-free in ext4_orphan_cleanup

A use-after-free vulnerability was found in the ext4 filesystem's orphan inode cleanup routine in the Linux kernel. When ext4inodeattachjinode fails with -ENOMEM during orphan cleanup at mount time, the error is not properly propagated. The inode is freed via iput, but the orphan list still...

kernel: ext4: fix bug_on in __es_tree_search caused by bad boot loader inode

A flaw was identified in the ext4 filesystem implementation in the Linux kernel where a malformed or improperly initialized boot loader inode could trigger a BUGON condition inside the estreesearch function. This occurs when the inode’s mode imode is an unexpected type and the code does not...

kernel: ext4: fix invalid free tracking in ext4_xattr_move_to_block()

A memory management flaw was found in the Linux kernel's ext4 filesystem extended attribute handling. In ext4xattrmovetoblock, when moving an extended attribute value to an external block, the code checks entry-evalueinum to determine if the buffer was allocated via kvmalloc. However, at cleanup...
