The md driver (drivers/md/md.c) in the Linux kernel before 2.6.30.2 might allow local users to cause a denial of service (NULL pointer dereference) via vectors related to "suspend_* sysfs attributes" and the (1) suspend_lo_store or (2) suspend_hi_store functions. NOTE: this is only a vulnerability when sysfs is writable by an attacker.
CVE-2009-2768 1 Linux 1 Linux Kernel 2026-04-23 7.8 High
The load_flat_shared_library function in fs/binfmt_flat.c in the flat subsystem in the Linux kernel before 2.6.31-rc6 allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact by executing a shared flat binary, which triggers an access of an "uninitialized cred pointer."
CVE-2009-2908 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-04-23 N/A
The d_delete function in fs/ecryptfs/inode.c in eCryptfs in the Linux kernel 2.6.31 allows local users to cause a denial of service (kernel OOPS) and possibly execute arbitrary code via unspecified vectors that cause a "negative dentry" and trigger a NULL pointer dereference, as demonstrated via a Mutt temporary directory in an eCryptfs mount.
CVE-2009-3547 8 Canonical, Fedoraproject, Linux and 5 more 17 Ubuntu Linux, Fedora, Linux Kernel and 14 more 2026-04-23 7.0 High
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.
CVE-2008-0172 3 Boost, Redhat, Ubuntu 3 Boost, Enterprise Linux, Ubuntu Linux 2026-04-23 N/A
The get_repeat_type function in basic_regex_creator.hpp in the Boost regex library (aka Boost.Regex) in Boost 1.33 and 1.34 allows context-dependent attackers to cause a denial of service (NULL dereference and crash) via an invalid regular expression.

The init_posix_timers function in kernel/posix-timers.c in the Linux kernel before 2.6.31-rc6 allows local users to cause a denial of service (OOPS) or possibly gain privileges via a CLOCK_MONOTONIC_RAW clock_nanosleep call that triggers a NULL pointer dereference.
CVE-2007-0887 1 Gecad Technologies 1 Axigen Mail Server 2026-04-23 N/A
axigen 1.2.6 through 2.0.0b1 does not properly parse login credentials, which allows remote attackers to cause a denial of service (NULL dereference and application crash) via a base64-encoded "*\x00" sequence on the imap port (143/tcp).
