CVE-2025-29970

CVE-2025-29970 is a local privilege-escalation vulnerability in the Microsoft Brokering File System caused by a use-after-free condition. An authorized attacker could exploit this to elevate privileges on the host. Public documentation identifies the affected component and the root cause as a use...

CVE-2025-31493

Kirby CVE-2025-31493 affects versions prior to 3.9.8.3, 3.10.1.2, and 4.7.1 where dynamic collection names passed to collection() or $kirby->collection() can bypass validation, enabling path traversal. The missing check allowed traversal outside the configured collections root (and even Kirby ...

CISA Adds Five Known Exploited Vulnerabilities to Catalog

CISA has added five new vulnerabilities to its Known Exploited Vulnerabilities Catalog, based on evidence of active exploitation. CVE-2025-30400link is external Microsoft Windows DWM Core Library Use-After-Free Vulnerability CVE-2025-32701link is external Microsoft Windows Common Log File System...

grub2: fs/ufs: OOB write in the heap

A flaw was found in grub2. When reading a symbolic link's name from a UFS filesystem, grub2 fails to validate the string length taken as an input. The lack of validation may lead to a heap out-of-bounds write, causing data integrity issues and eventually allowing an attacker to circumvent secure...

grub2: UFS: Integer overflow may lead to heap based out-of-bounds write when handling symlinks

A flaw was found in grub2. When performing a symlink lookup, the grub's UFS module checks the inode's data size to allocate the internal buffer to read the file content, however, it fails to check if the symlink data size has overflown. When this occurs, grubmalloc may be called with a smaller...

kernel: udf: fix uninit-value use in udf_get_fileshortad

In the Linux kernel, the following vulnerability has been resolved: udf: fix uninit-value use in udfgetfileshortad Check for overflow when computing alen in udfcurrentaext to mitigate later uninit-value use in udfgetfileshortad KMSAN bug1. After applying the patch reproducer did not trigger any...

kernel: ext4: dax: fix overflowing extents beyond inode size when partially writing

An inode corruption flaw was found in the Linux kernel's Ext4 file system functionality related to how a user can interrupt a write using the daxiomaprwfunction. This flaw allows a local user to make non-fatal mistakes with Ext4, leading to a file system denial of service...

kernel: afs: Fix the setting of the server responding flag

A flaw was found in the Linux kernel's AFS Andrew File System module. This vulnerability occurs in the afswaitforoperation function, where the op-server pointer is not properly validated for NULL before being used. A local attacker with low privileges could exploit this flaw, leading to a system...

kernel: fsnotify: clear PARENT_WATCHED flags lazily

A flaw was found in the Linux kernel's fsnotify subsystem. When a parent directory stops watching its children, a race condition can occur during the clearing of PARENTWATCHED flags. This contention on the inode-ilock can lead to system unresponsiveness or softlockups, effectively causing a Denia...

kernel: NFSD: Prevent a potential integer overflow

A flaw was found in the Linux kernel's Network File System daemon NFSD. An integer overflow vulnerability exists in the callback response decoding process when handling excessively large tag lengths. A remote attacker could exploit this flaw by sending a specially crafted callback response to the...

kernel: mm: revert "mm: shmem: fix data-race in shmem_getattr()"

In the Linux kernel, the following vulnerability has been resolved: mm: revert "mm: shmem: fix data-race in shmemgetattr" Revert d949d1d14fa2 "mm: shmem: fix data-race in shmemgetattr" as suggested by Chuck 1. It is causing deadlocks when accessing tmpfs over NFS. As Hugh commented, "added just t...

kernel: cifs: Fix memory and information leak in smb3_reconfigure()

A memory and information leak vulnerability was found in the Linux kernel's CIFS/SMB3 filesystem driver. When smb3reconfigure fails during smb3syncsessionctxpasswords, the newly allocated password buffers newpassword and newpassword2 are not freed or securely erased. This causes a memory leak and...

kernel: afs: Fix the maximum cell name length

In the Linux kernel, the following vulnerability has been resolved: afs: Fix the maximum cell name length The kafs filesystem limits the maximum length of a cell to 256 bytes, but a problem occurs if someone actually does that: kafs tries to create a directory under /proc/net/afs/ with the name o...

kernel: nfsd: fix nfs4_openowner leak when concurrent nfsd4_open occur

In the Linux kernel, the following vulnerability has been resolved: nfsd: fix nfs4openowner leak when concurrent nfsd4open occur The action force umountumount -f will attempt to kill all rpctask even umount operation may ultimately fail if some files remain open. Consequently, if an action attemp...
