kernel: Null pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c

A flaw was found in the Linux kernel’s implementation of dropping sysctl entries. A local attacker who has access to load modules on the system can trigger a condition during module load failure and panic the system...

Denial Of Service (DoS)

linux is vulnerable to denial of service DoS. There is a net/ipv4/tcpinput.c signed integer overflow in tcpackupdatertt when userspace writes a very large integer to /proc/sys/net/ipv4/tcpminrttwlen, leading to a denial of service or possibly unspecified other impact, aka CID-19fad20d15a6...

CVE-2020-10773

A stack information leak flaw was found in s390/s390x in the Linux kernel’s memory manager functionality, where it incorrectly writes to the /proc/sys/vm/cmmtimeout file. This flaw allows a local user to see the kernel data...

UBUNTU-CVE-2020-10773

UBUNTU-CVE-2020-25212

A TOCTOU mismatch in the NFS client code in the Linux kernel before 5.8.3 could be used by local attackers to corrupt memory or possibly have unspecified other impact because a size check is in fs/nfs/nfs4proc.c instead of fs/nfs/nfs4xdr.c, aka CID-b4487b935452...

Microsoft Azure Sphere Normal World application /proc/self/mem unsigned code execution vulnerability

Summary A code execution vulnerability exists in the normal world’s signed code execution functionality of Microsoft Azure Sphere 20.05. A specially crafted shellcode can cause a process’ non-writable memory to be written. An attacker can execute a shellcode that modifies the program at runtime v...

CVE-2020-10773

A stack information leak flaw was found in s390/s390x in the Linux kernel’s memory manager functionality, where it incorrectly writes to the /proc/sys/vm/cmmtimeout file. This flaw allows a local user to see the kernel data. Mitigation Mitigation for this issue is either not available or the...

CVE-2020-0110

A flaw was found in the Pressure stall information subsystem. This flaw allows a local attacker with the ability to write to root-owned files to corrupt kernel stack memory. Mitigation As the attacker must have the ability to write to these files, a possible mitigation would be to reduce the acce...

CVE-2019-15790

Apport reads and writes information on a crashed process to /proc/pid with elevated privileges. Apport then determines which user the crashed process belongs to by reading /proc/pid through getpidinfo in data/apport. An unprivileged user could exploit this to read information about a privileged...

Linux Kernel /proc/pid/syscall information disclosure vulnerability

Summary An information disclosure vulnerability exists in the /proc/pid/syscall functionality of Linux Kernel 5.1 Stable and 5.4.66. More specifically, this issue has been introduced in v5.1-rc4 commit 631b7abacd02b88f4b0795c08b54ad4fc3e7c7c0 and is still present in v5.10-rc4, so it’s likely that...

ansible: svn module leaks password when specified as a parameter

A flaw was found in Ansible Engine. When a password is set with the argument "password" of svn module, it is used on svn command line, disclosing to other users within the same node. An attacker could take advantage by reading the cmdline file from that particular PID on the procfs...

ansible: insecure temporary directory when running become_user from become directive

A race condition flaw was found in Ansible Engine when running a playbook with an unprivileged become user. When Ansible needs to run a module with become user, the temporary directory is created in /var/tmp. This directory is created with "umask 77 && mkdir -p "; this operation does not fail if...

Denial Of Service (DoS)

Kernel is vulnerable to denial of service DoS. The proc file system could allow a local, unprivileged user to obtain sensitive information or possibly cause integrity issues...

Information Disclosure

kernel is vulnerable to information disclosure. The vulnerability exists as /proc/PID/io is world-readable by default. Previously, these files could be read without any further restrictions. A local, unprivileged user could read these files, belonging to other, possibly privileged processes to...
