Linux kernel denial of service vulnerability (CNVD-2018-24547)

Linux kernel is the kernel used by the open source operating system Linux. crypto subsystem is one of the cryptographic subsystems. Linux kerne versions prior to 4.15-rc4 have a security vulnerability in the crypto subsystem. Each afalgctx, when released instead of aeadtfm, removes the null...

DEBIAN-CVE-2018-14619

A flaw was found in the crypto subsystem of the Linux kernel before version kernel-4.15-rc4. The "null skcipher" was being dropped when each afalgctx was freed instead of when the aeadtfm was freed. This can cause the null skcipher to be freed while it is still in use leading to a local user bein...
