kernel: Linux kernel ext4: Information Disclosure via uninitialized memory leak in fast-commit journal

A flaw was found in the Linux kernel. A local attacker could exploit an information disclosure vulnerability by not properly zeroing out unused space at the end of fast-commit journal blocks in the ext4 filesystem. This could lead to the leakage of uninitialized memory to disk, potentially allowi...

kernel: Linux kernel (ext4): Memory leak due to improper handling of krealloc failure

A flaw was found in the Linux kernel's ext4 filesystem. This vulnerability occurs due to improper handling of memory allocation failures when the krealloc function returns NULL within ext4fcrecordmodifiedinode. A local user could potentially exploit this flaw, leading to a memory leak. This memor...

kernel: ext4: use-after-free in ext4_xattr_set_entry()

A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the extra inode size for extended attributes. This flaw allows a privileged local user to cause a system crash or other undefined behaviors...

kernel: ext4: don't set up encryption key during jbd2 transaction

A flaw exists in the ext4 filesystem implementation in the Linux kernel such that the function ext4unlink extended a journaling transaction too far so that it included a call to ext4findentry. However, ext4findentry may need to set up a directory’s encryption key — which can cause a deadlock when...

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: avoid resizing to a partial cluster size

In the Linux kernel, the following vulnerability has been resolved: ext4: avoid resizing to a partial cluster size This patch avoids an attempt to resize the filesystem to an unaligned cluster boundary. An online resize to a size that is not integral to cluster size results in the last iteration...

kernel: ext4: block range must be validated before use in ext4_mb_clear_bb()

A use-after-free vulnerability exists in the linux kernel, such thatthe Block range to free is validated in ext4freeblocks using ext4inodeblockvalid and then it's passed to ext4mbclearbb.However, in some situations on bigalloc file system the range might be adjusted after the validation in...

kernel: ext4: fix deadlock due to mbcache entry corruption

A deadlock vulnerability was found in the ext4 filesystem in the Linux kernel. When manipulating extended attribute xattr blocks, a race condition in non-atomic bitfield updates can cause the mbcache entry state to become corrupted. This leads to an infinite loop in ext4xattrblockset where the co...

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...

PT-2023-15365 · Unknown · Ext4Fsfilter Driver

Name of the Vulnerable Software and Affected Versions: ext4fsfilter driver affected versions not specified Description: The issue is related to a missing bounds check in the ext4fsfilter driver, which can lead to a possible out of bounds read. This could result in a local denial of service and...

CVE-2023-31476

An issue was discovered on GL.iNet devices running firmware before 3.216. There is an arbitrary file write in which an empty file can be created almost anywhere on the filesystem, as long as the filename and path is no more than 6 characters the working directory is /www...
