Denial Of Service (DoS)

Linux kernel is vulnerable to denial of service attacks. This is due to a missing processor feature check and an erroneous use of transactional memory TM instructions in the core dump path. A crash can be triggered from unprivileged userspace during core dump on a POWER system with a certain...

Amazon Linux 2 : kernel (ALAS-2018-1023)

A weakness was found in the Linux kernel's implementation of random seed data. Programs, early in the boot sequence, could use the data allocated for the seed before it was sufficiently generated. CVE-2018-1108 A flaw was found in the way the Linux kernel handled exceptions delivered after a stac...

kernel: guest kernel crash during core dump on POWER9 host

A flaw was found in the Linux kernel where a crash can be triggered from unprivileged userspace during core dump on a POWER system with a certain configuration. This is due to a missing processor feature check and an erroneous use of transactional memory TM instructions in the core dump path...
