Denial Of Service (DoS)

Linux kernel is vulnerable to denial of service. A local user is able to crash the kernel due to multiple race conditions in the ext4 filesystem implementation, by writing to a page that is associated with a different user's file after unsynchronized hole punching and page-fault handling...

Denial Of Service (DoS)

kernel-rt is vulnerable to denial of service DoS attacks. The vulnerability exists as the ext4fillsuper function in fs/ext4/super.c in the Linux kernel through 4.9.8 does not properly validate meta block groups, which allows physically proximate attackers to cause a denial of service out-of-bound...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS attacks. The vulnerability exists as the implementation of certain splicewrite file operations in the Linux kernel before 3.16 does not enforce a restriction on the maximum size of a single file, which allows local users to cause a denial of service...

Information Disclosure

Linux kernel is vulnerable to information disclosure. A race condition in fs/ext4/extents.c when using ext4 file system allows a local unprivileged user to retrieve confidential information from a deleted file whose data blocks have not yet been written...

Denial Of Service (DoS)

kernel-rt is vulnerable to denial of service. Incorrect handling of the Delay and Unwritten buffer head states in the journalunmapbuffer function in fs/jbd2/transaction.c allows local attackers to crash systems that have an ext4 file system with a journal mounted...
