SUSE-SU-2024:1491-1 Security update for the Linux Kernel RT (Live Patch 0 for SLE 15 SP5)

This update for the Linux Kernel 5.14.21-15050011 fixes one issue. The following security issue was fixed: - CVE-2024-0775: Fixed a use-after-free flaw was found in the ext4remount in fs/ext4/super.c in ext4 bsc1219079...

kernel: ext4: kernel bug in ext4_write_inline_data_end()

A flaw was found in the openEuler kernel in Linux filesystem modules that allows an integer overflow via mounting a corrupted filesystem. This issue affects the openEuler kernel in versions from 4.19.90 through 4.19.90-2401.3 and 5.10.0-60.18.0 through 5.10.0-183.0.0...

kernel: ext4: add EXT4_IGET_BAD flag to prevent unexpected bad inode

In the Linux kernel, the following vulnerability has been resolved: ext4: add EXT4IGETBAD flag to prevent unexpected bad inode There are many places that will get unhappy and crash when ext4iget returns a bad inode. However, if iget the boot loader inode, allows a bad inode to be returned, becaus...

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...

kernel: ext4: avoid deadlock in fs reclaim with page writeback

In the Linux kernel, the following vulnerability has been resolved: ext4: avoid deadlock in fs reclaim with page writeback Ext4 has a filesystem wide lock protecting ext4writepages calls to avoid races with switching of journalled data flag or inode format. This lock can however cause a deadlock...

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 in ext4_mb_new_inode_pa() due to overflow

An integer overflow flaw was found in the Linux kernel's ext4 filesystem. In ext4mbnewinodepa, when calculating the end position of ext4freeextent, the computation can overflow ext4lblkt uint32 to zero. This occurs with large logical block numbers near UINTMAX, causing a BUGON assertion failure a...

In the Linux kernel, the following vulnerability has been resolved: ext4: fix bugon in estreesearch caused by bad quota inode We got a issue as fllows: ================================================================== kernel BUG at fs/ext4/extentsstatus.c:202! invalid opcode: 0000 1 PREEMPT SMP...

kernel: ext4: fix WARNING in mb_find_extent

A vulnerability was found in the ext4 filesystem driver in the Linux kernel. This flaw occurs when the system processes a maliciously crafted or corrupted ext4 filesystem image, as the driver fails to properly validate its structural data. A local user with the ability to mount such an image coul...

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: set goal start correctly in ext4_mb_normalize_request

A flaw was found in the Linux kernel's ext4 filesystem block allocator. In ext4mbnormalizerequest, the goal start was being set incorrectly acfex instead of acgex, and boundary validation was missing. Without proper range checking, an underflow in ar-pright - size could pass an invalid value to...
