Medium: kernel

Issue Overview: bpf: incorrect verifier pruning due to missing register precision taints, which may lead to out-of-band read/write access due to an incorrect verifier conclusion. CVE-2023-2163 A use-after-free vulnerability was found in the Linux kernel's ext4 filesystem in the way it handled the...

The vulnerability of the inode_init_owner() function in the fs/inode.c file of the XFS file system’s kernel of the Linux operating system allows a malicious actor to escalate their privileges and gain access to protected information. It can also cause service interruptions.

The vulnerability of the inodeinitowner function in the fs/inode.c file of the XFS file system in the Linux operating system is related to the incorrect setting of access group attributes during file creation. Exploiting this vulnerability can allow an attacker to enhance their privileges and gai...

PT-2025-37890

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel contains an issue in the ext4 filesystem related to bounds checking within the get max inline xattr value size function. A corruption of the inode table can occur if...

kernel: gfs2: Always check inode size of inline inodes

A flaw was found in the Linux kernel's GFS2 filesystem. A local attacker with low privileges could craft a malicious GFS2 filesystem with an out-of-range inode size for inline inodes. This improper handling of inode sizes when reading from disk could lead to on-disk corruption, resulting in a...

In the Linux kernel, the following vulnerability has been resolved: NFSv4.2 fix problems with nfs42sscopen A destination server while doing a COPY shouldn't accept using the passed in filehandle if its not a regular filehandle. If allocfilepseudo has failed, we need to decrement a reference on th...

kernel: ext4: silence the warning when evicting inode with dioread_nolock

In the Linux kernel, the following vulnerability has been resolved: ext4: silence the warning when evicting inode with dioreadnolock When evicting an inode with default dioreadnolock, it could be raced by the unwritten extents converting kworker after writeback some new allocated dirty blocks. It...

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: fix uninititialized value in 'ext4_evict_inode'

An uninitialized variable flaw was found in the Linux kernel's ext4 filesystem in the inode eviction path. A local user can trigger this issue by creating filesystem operations that cause inode allocation to fail before the iflags field is initialized, followed by inode cleanup that attempts to...

kernel: writeback: avoid use-after-free after removing device

In the Linux kernel, the following vulnerability has been resolved: writeback: avoid use-after-free after removing device When a disk is removed, bdiunregister gets called to stop further writeback and wait for associated delayed work to complete. However, wbinodewritebackend may schedule bandwid...
