kernel: improper initialization of the "flags" member of the new pipe_buffer

A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copypagetoiterpipe and pushpipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cach...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux Foundation's open source operating system Linux. A security vulnerability exists in the Linux kernel due to a lack of proper initialization of the "flag" variable of the new pipe buffer structure in the copypagetoiterpipe and pushpipe functions in...

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,...

UBUNTU-CVE-2020-15254

Crossbeam is a set of tools for concurrent programming. In crossbeam-channel before version 0.4.4, the bounded channel incorrectly assumes that Vec::fromiter has allocated capacity that same as the number of iterator elements. Vec::fromiter does not actually guarantee that and may allocate extra...
