The mem_cgroup_usage_unregister_event function in mm/memcontrol.c in the Linux kernel before 3.2.10 does not properly handle multiple events that are attached to the same eventfd, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by registering memory threshold events.
CVE-2012-1097 3 Linux, Redhat, Suse 6 Linux Kernel, Enterprise Linux, Enterprise Mrg and 3 more 2023-02-12 7.2 HIGH 7.8 HIGH
The regset (aka register set) feature in the Linux kernel before 3.2.10 does not properly handle the absence of .get and .set methods, which allows local users to cause a denial of service (NULL pointer dereference) or possibly have unspecified other impact via a (1) PTRACE_GETREGSET or (2) PTRACE_SETREGSET ptrace call.
CVE-2011-2928 1 Linux 1 Linux Kernel 2023-02-12 4.9 MEDIUM N/A
The befs_follow_link function in fs/befs/linuxvfs.c in the Linux kernel before 3.1-rc3 does not validate the length attribute of long symlinks, which allows local users to cause a denial of service (incorrect pointer dereference and OOPS) by accessing a long symlink on a malformed Be filesystem.
CVE-2011-4081 1 Linux 1 Linux Kernel 2023-02-12 4.9 MEDIUM 5.5 MEDIUM
crypto/ghash-generic.c in the Linux kernel before 3.1 allows local users to cause a denial of service (NULL pointer dereference and OOPS) or possibly have unspecified other impact by triggering a failed or missing ghash_setkey function call, followed by a (1) ghash_update function call or (2) ghash_final function call, as demonstrated by a write operation on an AF_ALG socket.
CVE-2011-2691 3 Debian, Fedoraproject, Libpng 3 Debian Linux, Fedora, Libpng 2023-02-12 4.3 MEDIUM 6.5 MEDIUM
The png_err function in pngerror.c in libpng 1.0.x before 1.0.55, 1.2.x before 1.2.45, 1.4.x before 1.4.8, and 1.5.x before 1.5.4 makes a function call using a NULL pointer argument instead of an empty-string argument, which allows remote attackers to cause a denial of service (application crash) via a crafted PNG image.
CVE-2011-1771 1 Linux 1 Linux Kernel 2023-02-12 4.4 MEDIUM 7.8 HIGH
The cifs_close function in fs/cifs/file.c in the Linux kernel before 2.6.39 allows local users to cause a denial of service (NULL pointer dereference and BUG) or possibly have unspecified other impact by setting the O_DIRECT flag during an attempt to open a file on a CIFS filesystem.
