CVE-2023-2163 NOMISEC CRITICAL STUB
Linux Kernel >=5.4 - Privilege Escalation
Incorrect verifier pruning in BPF in Linux Kernel >=5.4 leads to unsafe code paths being incorrectly marked as safe, resulting in arbitrary read/write in kernel memory, lateral privilege escalation, and container escape.

CVE-2026-43494 GITHUB HIGH c WORKING POC
net/rds: reset op_nents when zerocopy page pin fails
In the Linux kernel, the following vulnerability has been resolved: net/rds: reset op_nents when zerocopy page pin fails When iov_iter_get_pages2() fails in rds_message_zcopy_from_user(), the pinned pages are released with put_page(), and rm->data.op_mmp_znotifier is cleared. But we fail to properly clear rm->data.op_nents. Later when rds_message_purge() is called from rds_sendmsg() the cleanup loop iterates over the incorrectly non zero number of op_nents and frees them again. Fix this by properly resetting op_nents when it should be in rds_message_zcopy_from_user().

CVE-2023-0386 NOMISEC HIGH STUB
Local Privilege Escalation via CVE-2023-0386
A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel’s OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allows a local user to escalate their privileges on the system.

CVE-2022-2639 NOMISEC HIGH NO CODE
Openvswitch kernel module - Memory Corruption
An integer coercion error was found in the openvswitch kernel module. Given a sufficiently large number of actions, while copying and reserving memory for a new action of a new flow, the reserve_sfa_size() function does not return -EMSGSIZE as expected, potentially leading to an out-of-bounds write access. This flaw allows a local user to crash or potentially escalate their privileges on the system.

CVE-2022-0847 NOMISEC HIGH STUB
Dirty Pipe Local Privilege Escalation via CVE-2022-0847
A flaw was found in the way the "flags" member of the new pipe buffer structure was lacking proper initialization in copy_page_to_iter_pipe and push_pipe functions in the Linux kernel and could thus contain stale values. An unprivileged local user could use this flaw to write to pages in the page cache backed by read only files and as such escalate their privileges on the system.

CVE-2021-22555 NOMISEC HIGH WORKING POC
Netfilter x_tables Heap OOB Write Privilege Escalation
A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c. This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space

CVE-2021-22555 NOMISEC HIGH NO CODE
Netfilter x_tables Heap OOB Write Privilege Escalation
A heap out-of-bounds write affecting Linux since v2.6.19-rc1 was discovered in net/netfilter/x_tables.c. This allows an attacker to gain privileges or cause a DoS (via heap memory corruption) through user name space

CVE-2019-18634 NOMISEC HIGH STUB
sudo 1.7.1-1.8.25 - Stack-based Buffer Overflow via pwfeedback
In Sudo before 1.8.26, if pwfeedback is enabled in /etc/sudoers, users can trigger a stack-based buffer overflow in the privileged sudo process. (pwfeedback is a default setting in Linux Mint and elementary OS; however, it is NOT the default for upstream and many other packages, and would exist only if enabled by an administrator.) The attacker needs to deliver a long string to the stdin of getln() in tgetpass.c.

CVE-2019-13272 NOMISEC HIGH WORKING POC
Linux Polkit pkexec helper PTRACE_TRACEME local root exploit
In the Linux kernel before 5.1.17, ptrace_link in kernel/ptrace.c mishandles the recording of the credentials of a process that wants to create a ptrace relationship, which allows local users to obtain root access by leveraging certain scenarios with a parent-child process relationship, where a parent drops privileges and calls execve (potentially allowing control by an attacker). One contributing factor is an object lifetime issue (which can also cause a panic). Another contributing factor is incorrect marking of a ptrace relationship as privileged, which is exploitable through (for example) Polkit's pkexec helper with PTRACE_TRACEME. NOTE: SELinux deny_ptrace might be a usable workaround in some environments.

CVE-2017-1000367 NOMISEC MEDIUM WORKING POC
Todd Miller's sudo <1.8.20 - Info Disclosure & Command Execution
Todd Miller's sudo version 1.8.20 and earlier is vulnerable to an input validation (embedded spaces) in the get_process_ttyname() function resulting in information disclosure and command execution.

CVE-2013-2094 NOMISEC HIGH WORKING POC
Linux Kernel < 3.0.75 - Local Privilege Escalation via perf_event_open System Call
The perf_swevent_init function in kernel/events/core.c in the Linux kernel before 3.8.9 uses an incorrect integer data type, which allows local users to gain privileges via a crafted perf_event_open system call.
