CVE-2019-16234 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
Al Viro discovered that the Linux kernel for s390x systems did not properly
perform page table upgrades for kernel sections that use secondary address
mode. A local attacker could use this to cause a denial of service (system
crash) or execute arbitrary code. (CVE-2020-11884)
It was discovered that the Intel Wi-Fi driver in the Linux kernel did not
properly check for errors in some situations. A local attacker could
possibly use this to cause a denial of service (system crash).

CVE-2019-19768 [HIGH] CVE-2019-19768 kernel: use-after-free in __blk_add_trace in kernel/trace/blktrace.c
CVE-2019-19768 kernel: use-after-free in __blk_add_trace in kernel/trace/blktrace.c
A use-after-free flaw was found in the Linux kernels implementation of blktrace in the __blk_add_trace function. A local attacker with permissions to run block trace instructions against a device can create a situation where the core block_trace object is used after it is freed. The attacker can pre-groom memory to race this use-after-free to create a condition where memory is corrupted and also likely to be privilege escalation.
The ability to create this condition requires elevated privileges, and it has been decided that this change in Red Hat Enterprise Linux 5 and 6 would risk introducing possible regressions and will not be backported.
