kernel: Information Disclosure in crypto_report_one in crypto/crypto_user.c

An issue was discovered in the Linux kernel in the cryptoreportone and related functions in the crypto/cryptouser.c the crypto user configuration API which do not fully initialize structures that are copied to userspace, potentially leaking sensitive kernel memory content to a userspace...

ARM: Interrupts are unconditionally unmasked in exception handlers

ISSUE DESCRIPTION When an exception occurs on an ARM system which is handled without changing processor level, some interrupts are unconditionally enabled during exception entry. So exceptions which occur when interrupts are masked will effectively unmask the interrupts. IMPACT A malicious guest...

CVE-2018-20855

A flaw was discovered in the Linux kernel's implementation of InfiniBand. A local attacker who is able to execute a read from the InfiniBand device could trigger an information leak of kernel memory to userspace which can be used to further attack the system. Mitigation If the InfiniBand device i...
