A flaw was found in the way the Linux kernel’s SCTP implementation validated INIT chunks when performing Address Configuration Change (ASCONF). A remote attacker could use this flaw to crash the system by sending a specially crafted SCTP packet to trigger a NULL pointer dereference on the system. (CVE-2014-7841, Important)
A race condition flaw was found in the way the Linux kernel’s mmap(2), madvise(2), and fallocate(2) system calls interacted with each other while operating on virtual memory file system files. A local user could use this flaw to cause a denial of service. (CVE-2014-4171, Moderate)
A NULL pointer dereference flaw was found in the way the Linux kernel’s Common Internet File System (CIFS) implementation handled mounting of file system shares. A remote attacker could use this flaw to crash a client system that would mount a file system share from a malicious server. (CVE-2014-7145, Moderate)
A flaw was found in the way the Linux kernel’s splice() system call validated its parameters. On certain file systems, a local, unprivileged user could use this flaw to write past the maximum file size, and thus crash the system. (CVE-2014-7822, Moderate)
It was found that the parse_rock_ridge_inode_internal() function of the Linux kernel’s ISOFS implementation did not correctly check relocated directories when processing Rock Ridge child link (CL) tags. An attacker with physical access to the system could use a specially crafted ISO image to crash the system or, potentially, escalate their privileges on the system. (CVE-2014-5471, CVE-2014-5472, Low)
This update also fixes the following bugs :
Previously, a kernel panic could occur if a process reading from a locked NFS file was killed and the lock was not released properly before the read operations finished. Consequently, the system crashed. The code handling file locks has been fixed, and instead of halting, the system now emits a warning about the unreleased lock.
A race condition in the command abort handling logic of the ipr device driver could cause the kernel to panic when the driver received a response to an abort command prior to receiving other responses to the aborted command due to the support for multiple interrupts. With this update, the abort handler waits for the aborted command’s responses first before completing an abort operation.
Previously, a race condition could occur when changing a Page Table Entry (PTE) or a Page Middle Directory (PMD) to ‘pte_numa’ or ‘pmd_numa’, respectively, causing the kernel to crash. This update removes the BUG_ON() macro from the __handle_mm_fault() function, preventing the kernel panic in the aforementioned scenario.
The system must be rebooted for this update to take effect.
