hw: Intel GPU Denial Of Service while accessing MMIO in lower power state

A flaw was found in Intel graphics hardware GPU where a local attacker with the ability to issue an ioctl could trigger a hardware level crash if MMIO registers were read while the graphics card was in a low-power state. This creates a denial of service situation and the GPU and connected display...

Debian DLA-1823-1 : linux security update (SACK Panic) (SACK Slowness)

Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. CVE-2019-3846, CVE-2019-10126 huangwen reported multiple buffer overflows in the Marvell wifi mwifiex driver, which a local user could use to cause...

Denial Of Service (DoS)

Linux kernel is vulnerable to denial of service attacks. A race condition between direct and memory-mapped I/O which is handled with BUGON instead of an I/O failure enables local users to cause a denial of service via system crash. Affected is the functionality of file fs/xfs/xfsaops.c of the...

Directory Traversal

servlets-default is vulnerable to directory traversal attacks. The vulnerability exists due to default configuration of enabling directory traversal, allowing directories to be listed with a ; after a filename with a mapped extension...

kernel: fuse-backed file mmap-ed onto process cmdline arguments causes denial of service

By mmaping a FUSE-backed file onto a process's memory containing command line arguments or environment strings, an attacker can cause utilities from psutils or procps such as ps, w or any other program which makes a read call to the /proc//cmdline or /proc//environ files to block indefinitely...
