Denial Of Service (DoS)
kernel is vulnerable to denial of service DoS. The vulnerability exists as a flaw was found in ptrace support that allowed a local user to cause a denial of service via a NULL pointer dereference...
kernel: perf_event_open() and execve() race in setuid programs allows a data leak
A race condition in perfeventopen allows local attackers to leak sensitive data from setuid programs. As no relevant locks in particular the credguardmutex are held during the ptracemayaccess call, it is possible for the specified target task to perform an execve syscall with setuid execution...

BSA-2020-918
Security Advisory ID : BSA-2020-918 Component : Linux Kernel Revision : 1.0: Final The Linux kernel before 2.4.36-rc1 has a race condition. It was possibleto bypass systrace policies by flooding the ptraced process with SIGCONTsignals, which can can wake up a PTRACED process...
Linux ptrace Disclosure
The vulnerability of the ptrace subsystem in the Linux operating system is related to errors in implementing measures to protect against Spectre-class vulnerabilities. Exploiting this vulnerability can allow an attacker to exploit the protected mechanisms...

It was discovered that the RSI 91x Wi-Fi driver in the Linux kernel did not did not handle detach operations correctly, leading to a use-after-free vulnerability. A physically proximate attacker could use this to cause a denial of service system crash or possibly execute arbitrary code...
USN-4157-2 linux-hwe, linux-azure, linux-gcp, linux-gke-5.0 vulnerabilities
USN-4157-1 fixed vulnerabilities in the Linux kernel for Ubuntu 19.04. This update provides the corresponding updates for the Linux Hardware Enablement HWE kernel from Ubuntu 19.04 for Ubuntu 18.04 LTS. Wen Huang discovered that the Marvell Wi-Fi device driver in the Linux kernel did not properly...
Ubuntu 19.04 : Linux kernel vulnerabilities (USN-4157-1)
Wen Huang discovered that the Marvell Wi-Fi device driver in the Linux kernel did not properly perform bounds checking, leading to a heap overflow. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2019-14814, CVE-2019-14815,...
Debian DSA-4531-1 : linux - security update
Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks. - CVE-2019-14821 Matt Delco reported a race condition in KVM's coalesced MMIO facility, which could lead to out-of-bounds access in the kernel. A local...
kernel: broken permission and object lifetime handling for PTRACE_TRACEME
A flaw was found in the way PTRACETRACEME functionality was handled in the Linux kernel. The kernel's implementation of ptrace can inadvertently grant elevated permissions to an attacker who can then abuse the relationship between the tracer and the process being traced. This flaw could allow a...
