kernel: block: don't delete queue kobject before its children

In the Linux kernel, the following vulnerability has been resolved: block: don't delete queue kobject before its children kobjects aren't supposed to be deleted before their child kobjects are deleted. Apparently this is usually benign; however, a WARN will be triggered if one of the child kobjec...

The vulnerability of the `blk_mq_free_rqs` and `blk_cleanup_queue` functions in the Linux kernel’s block subsystem, related to memory usage after deallocation, allows attackers to gain access to confidential data, compromise its integrity, and cause service failures.

The vulnerability of the blkmqfreerqs and blkcleanupqueue functions in the Linux kernel’s block subsystem relates to the use of memory after it is freed. Exploiting this vulnerability can allow an attacker to access confidential data, compromise its integrity, and cause service failures...

CVE-2019-25044

A flaw was found in the Linux kernel. The block subsystem has a use-after-free that can lead to arbitrary code execution in the kernel context and privilege escalation. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability...

CVE-2019-25044

The block subsystem in the Linux kernel before 5.2 has a use-after-free that can lead to arbitrary code execution in the kernel context and privilege escalation, aka CID-c3e2219216c9. This is related to blkmqfreerqs and blkcleanupqueue...

kernel: soft-lockups in iov_iter_copy_from_user_atomic() could result in DoS

A flaw was found in the Linux kernel’s implementation of biovecs. A zero-length biovec request issued by the block subsystem could cause the kernel to enter an infinite loop, causing a denial of service. This flaw allows a local attacker with basic privileges to issue requests to a block device,...
