Linux kernel denial of service vulnerability (CNVD-2018-24546)

Linux kernel is the kernel used by Linux, the open source operating system released by the Linux Foundation in the United States. A security vulnerability exists in the 'xenvifsethashmapping' function in the drivers/net/xen-netback/hash.c file in Linux kernel 4.18.1 and earlier, which stems from...

CVE-2018-15471

A flaw in the netback module allowed frontends to control mapping of requests to request queues. An attacker can change this mapping by requesting invalid mapping requests allowing the usually privileged backend to access out-of-bounds memory access for reading and writing...

DEBIAN-CVE-2018-15471

An issue was discovered in xenvifsethashmapping in drivers/net/xen-netback/hash.c in the Linux kernel through 4.18.1, as used in Xen through 4.11.x and other products. The Linux netback driver allows frontends to control mapping of requests to request queues. When processing a request to set or...

CVE-2018-15471

CVE-2018-15471 affects the Linux kernel Xen netback driver: the xenvif_set_hash_mapping function in drivers/net/xen-netback/hash.c handles request queue mapping with insufficient input validation (e.g., for integer overflow), causing out-of-bounds memory access. This can allow a malicious or bugg...
