CVE-2021-41073

looprwiter in fs/iouring.c in the Linux kernel 5.10 through 5.14.6 allows local users to gain privileges by using IORINGOPPROVIDEBUFFERS to trigger a free of a kernel buffer, as demonstrated by using /proc//maps for exploitation...

CVE-2021-25682

It was discovered that the getpidinfo function in data/apport did not properly parse the /proc/pid/status file from the kernel...

CVE-2020-28588

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 all...

CVE-2020-28588

The CVE-2020-28588 information disclosure exists in the Linux Kernel /proc/pid/syscall interface for 5.1 Stable through 5.4.66, introduced in v5.1-rc4 (commit 631b7abacd02b88f4b0795c08b54ad4fc3e7c7c0) and still present in 5.10-rc4. An attacker can read /proc/pid/syscall to trigger memory contents...

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...

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...

Information Disclosure

kernel is vulnerable to information disclosure. An information leak was found in the Linux kernel's taskshowregs implementation. On IBM S/390 systems, a local, unprivileged user could use this flaw to read /proc/PID/status files, allowing them to discover the CPU register values of processes...

Race condition

A race condition flaw was found in Ansible Engine 2.7.17 and prior, 2.8.9 and prior, 2.9.6 and prior 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...

UBUNTU-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...

kernel: Unprivileged users able to inspect kernel stacks of arbitrary tasks

An issue was discovered in the procpidstack function in fs/proc/base.c in the Linux kernel. An attacker with a local account can trick the stack unwinder code to leak stack contents to userspace. The fix allows only root to inspect the kernel stack of an arbitrary task...

Ubuntu 16.04 LTS : Sudo vulnerabilities (USN-3968-1)

The remote Ubuntu 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3968-1 advisory. Florian Weimer discovered that Sudo incorrectly handled the noexec restriction when used with certain applications. A local attacker could possibly use...

CVE-2019-11190

The Linux kernel before 4.8 allows local users to bypass ASLR on setuid programs such as /bin/su because installexeccreds is called too late in loadelfbinary in fs/binfmtelf.c, and thus the ptracemayaccess check has a race condition when reading /proc/pid/stat...

DEBIAN-CVE-2018-17972

An issue was discovered in the procpidstack function in fs/proc/base.c in the Linux kernel through 4.18.11. It does not ensure that only root may inspect the kernel stack of an arbitrary task, allowing a local attacker to exploit racy stack unwinding and leak kernel task stack contents...
