Linux Kernel < 3.14.3 - Denial of Service and Privilege Escalation via Race Condition in n_tty_write
The n_tty_write function in drivers/tty/n_tty.c in the Linux kernel through 3.14.3 does not properly manage tty driver access in the "LECHO & !OPOST" case, which allows local users to cause a denial of service (memory corruption and system crash) or gain privileges by triggering a race condition involving read and write operations with long strings.

CVSS 8.4
Linux Kernel < 3.8.9 - Privilege Escalation via uid_map and gid_map File Handling
kernel/user_namespace.c in the Linux kernel before 3.8.9 does not have appropriate capability requirements for the uid_map and gid_map files, which allows local users to gain privileges by opening a file within an unprivileged process and then modifying the file within a privileged process.
by Andyyyyuan
Linux Kernel < 3.8.3 - Privilege Escalation via CLONE_NEWUSER and CLONE_FS Flag Combination
The clone system-call implementation in the Linux kernel before 3.8.3 does not properly handle a combination of the CLONE_NEWUSER and CLONE_FS flags, which allows local users to gain privileges by calling chroot and leveraging the sharing of the / directory between a parent process and a child process.
by Andyyyyuan
Linux Kernel < 3.7.6 - Local Privilege Escalation via MSR Device Access
The msr_open function in arch/x86/kernel/msr.c in the Linux kernel before 3.7.6 allows local users to bypass intended capability restrictions by executing a crafted application as root, as demonstrated by msr32.c.

Linux Kernel < 3.0.18 - Privilege Escalation via /proc/<pid>/mem Write
The mem_write function in the Linux kernel before 3.2.2, when ASLR is disabled, does not properly check permissions when writing to /proc/<pid>/mem, which allows local users to gain privileges by modifying process memory, as demonstrated by Mempodipper.
by Andyyyyuan
ktsuss suid Privilege Escalation
ktsuss versions 1.4 and prior has the uid set to root and does not drop privileges prior to executing user specified commands, which can result in command execution with root privileges.

CVSS 9.8
Linux PolicyKit Race Condition Privilege Escalation
Race condition in the pkexec utility and polkitd daemon in PolicyKit (aka polkit) 0.96 allows local users to gain privileges by executing a setuid program from pkexec, related to the use of the effective user ID instead of the real user ID.
by Andyyyyuan
Linux Kernel < 2.6.36.2 - Privilege Escalation via ACPI Debugfs Custom Method
The ACPI subsystem in the Linux kernel before 2.6.36.2 uses 0222 permissions for the debugfs custom_method file, which allows local users to gain privileges by placing a custom ACPI method in the ACPI interpreter tables, related to the acpi_debugfs_init function in drivers/acpi/debugfs.c.

SystemTap 1.3 - Privilege Escalation via MODPROBE_OPTIONS Environment Variable
The staprun runtime tool in SystemTap 1.3 does not properly clear the environment before executing modprobe, which allows local users to gain privileges by setting the MODPROBE_OPTIONS environment variable to specify a malicious configuration file.
by Andyyyyuan
Linux kernel <2.6.36.2 - Privilege Escalation
The ec_dev_ioctl function in net/econet/af_econet.c in the Linux kernel before 2.6.36.2 does not require the CAP_NET_ADMIN capability, which allows local users to bypass intended access restrictions and configure econet addresses via an SIOCSIFADDR ioctl call.
by Andyyyyuan
Linux Kernel < 2.6.36.2 - Denial of Service via NULL Pointer Dereference in econet_sendmsg
The econet_sendmsg function in net/econet/af_econet.c in the Linux kernel before 2.6.36.2, when an econet address is configured, allows local users to cause a denial of service (NULL pointer dereference and OOPS) via a sendmsg call that specifies a NULL value for the remote address field.
by Andyyyyuan
Linux kernel <2.6.36-rc6 - Info Disclosure/DoS
Integer signedness error in the pkt_find_dev_from_minor function in drivers/block/pktcdvd.c in the Linux kernel before 2.6.36-rc6 allows local users to obtain sensitive information from kernel memory or cause a denial of service (invalid pointer dereference and system crash) via a crafted index value in a PKT_CTRL_CMD_STATUS ioctl call.
by Andyyyyuan
Linux kernel <2.6.36-rc4-git2 - Privilege Escalation
The compat_alloc_user_space functions in include/asm/compat.h files in the Linux kernel before 2.6.36-rc4-git2 on 64-bit platforms do not properly allocate the userspace memory required for the 32-bit compatibility layer, which allows local users to gain privileges by leveraging the ability of the compat_mc_getsockopt function (aka the MCAST_MSFILTER getsockopt support) to control a certain length value, related to a "stack pointer underflow" issue, as exploited in the wild in September 2010.

CVSS 7.8
Linux kernel <2.6.33.2 - Privilege Escalation
The Linux kernel 2.6.33.2 and earlier, when a ReiserFS filesystem exists, does not restrict read or write access to the .reiserfs_priv directory, which allows local users to gain privileges by modifying (1) extended attributes or (2) ACLs, as demonstrated by deleting a file under .reiserfs_priv/xattrs/.

libpam-modules <1.1.0-2ubuntu1.1/1.1.1-2ubuntu5 - Privilege Escalation
pam_motd (aka the MOTD module) in libpam-modules before 1.1.0-2ubuntu1.1 in PAM on Ubuntu 9.10 and libpam-modules before 1.1.1-2ubuntu5 in PAM on Ubuntu 10.04 LTS allows local users to change the ownership of arbitrary files via a symlink attack on .cache in a user's home directory, related to "user file stamps" and the motd.legal-notice file.
by Andyyyyuan
Linux Kernel < 2.6.32-rc6 - Race Condition in Pipe Handling via /proc/*/fd/ Pathname
Multiple race conditions in fs/pipe.c in the Linux kernel before 2.6.32-rc6 allow local users to cause a denial of service (NULL pointer dereference and system crash) or gain privileges by attempting to open an anonymous pipe via a /proc/*/fd/ pathname.

CVSS 7.0
Linux Kernel <2.6.19 - Privilege Escalation
The udp_sendmsg function in the UDP implementation in (1) net/ipv4/udp.c and (2) net/ipv6/udp.c in the Linux kernel before 2.6.19 allows local users to gain privileges or cause a denial of service (NULL pointer dereference and system crash) via vectors involving the MSG_MORE flag and a UDP socket.

CVSS 7.8
Linux kernel <2.6.30.4, <2.4.37.4 - Privilege Escalation
The Linux kernel 2.6.0 through 2.6.30.4, and 2.4.4 through 2.4.37.4, does not initialize all function pointers for socket operations in proto_ops structures, which allows local users to trigger a NULL pointer dereference and gain privileges by using mmap to map page zero, placing arbitrary code on this page, and then invoking an unavailable operation, as demonstrated by the sendpage operation (sock_sendpage function) on a PF_PPPOX socket.

CVSS 7.8
Linux kernel <2.6.31-rc3 - Memory Corruption
The personality subsystem in the Linux kernel before 2.6.31-rc3 has a PER_CLEAR_ON_SETID setting that does not clear the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags when executing a setuid or setgid program, which makes it easier for local users to leverage the details of memory usage to (1) conduct NULL pointer dereference attacks, (2) bypass the mmap_min_addr protection mechanism, or (3) defeat address space layout randomization (ASLR).

udev < 141 - Privilege Escalation via Unverified NETLINK Message
udev before 1.4.1 does not verify whether a NETLINK message originates from kernel space, which allows local users to gain privileges by sending a NETLINK message from user space.
by Andyyyyuan
Linux Kernel < 2.6.22 - Privilege Escalation via Setuid/Setgid Bit Handling
fs/open.c in the Linux kernel before 2.6.22 does not properly strip setuid and setgid bits when there is a write to a file, which allows local users to gain the privileges of a different group, and obtain sensitive information or possibly have unspecified other impact, by creating an executable file in a setgid directory through the (1) truncate or (2) ftruncate function in conjunction with memory-mapped I/O.
