A flaw was found in the Linux kernel’s block driver implementation blkdrainqueue function where a use-after-free condition could be triggered while draining the outstanding command queue in the systems block device subsystem. An attacker could use this flaw to crash the system or corrupt local...

iOS 12.4 jailbreak released after Apple 'accidentally un-patches' an old flaw

A fully functional jailbreak has been released for the latest iOS 12.4 on the Internet, making it the first public jailbreak in a long time—thanks to Apple. Dubbed "unc0ver 3.5.0 ," the jailbreak works with the updated iPhones, iPads and iPod Touches by leveraging a vulnerability that Apple...

DEBIAN-CVE-2017-18550

An issue was discovered in drivers/scsi/aacraid/commctrl.c in the Linux kernel before 4.13. There is potential exposure of kernel stack memory because aacgethbainfo does not initialize the hbainfo structure...

kernel: dereferencing NULL payload with nonzero length

A flaw was found in the implementation of associative arrays where the addkey systemcall and KEYCTLUPDATE operations allowed for a NULL payload with a nonzero length. When accessing the payload within this length parameters value, an unprivileged user could trivially cause a NULL pointer...

The vulnerability in the XNU kernel of iOS, Mac OS, and TV OS allows attackers to perform unauthorized changes to the memory shared among processes.

The vulnerability of the XNU-based operating systems such as iOS, Mac OS, and TV OS is related to errors in the memory initialization mechanism. Exploiting this vulnerability allows an attacker to perform unauthorized changes to the memory shared among processes, using specially crafted executabl...

UBUNTU-CVE-2019-10126
