CVE-2009-1897 1 Linux 1 Linux Kernel 2026-04-23 N/A
The tun_chr_poll function in drivers/net/tun.c in the tun subsystem in the Linux kernel 2.6.30 and 2.6.30.1, when the -fno-delete-null-pointer-checks gcc option is omitted, allows local users to gain privileges via vectors involving a NULL pointer dereference and an mmap of /dev/net/tun, a different vulnerability than CVE-2009-1894.
CVE-2007-1497 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-04-23 N/A
nf_conntrack in netfilter in the Linux kernel before 2.6.20.3 does not set nfctinfo during reassembly of fragmented packets, which leaves the default value as IP_CT_ESTABLISHED and might allow remote attackers to bypass certain rulesets using IPv6 fragments.
CVE-2008-2944 3 Fedoraproject, Linux, Redhat 3 Fedora Core, Linux Kernel, Enterprise Linux 2026-04-23 N/A
Double free vulnerability in the utrace support in the Linux kernel, probably 2.6.18, in Red Hat Enterprise Linux (RHEL) 5 and Fedora Core 6 (FC6) allows local users to cause a denial of service (oops), as demonstrated by a crash when running the GNU GDB testsuite, a different vulnerability than CVE-2008-2365.

Memory leak in the keyctl_join_session_keyring function (security/keys/keyctl.c) in Linux kernel 2.6.29-rc2 and earlier allows local users to cause a denial of service (kernel memory consumption) via unknown vectors related to a "missing kfree."
CVE-2007-3104 2 Linux, Redhat 2 Linux Kernel, Enterprise Linux 2026-04-23 N/A
The sysfs_readdir function in the Linux kernel 2.6, as used in Red Hat Enterprise Linux (RHEL) 4.5 and other distributions, allows users to cause a denial of service (kernel OOPS) by dereferencing a null pointer to an inode in a dentry.
CVE-2009-2692 4 Debian, Linux, Redhat and 1 more 11 Debian Linux, Linux Kernel, Enterprise Linux and 8 more 2026-04-23 7.8 High
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.
CVE-2009-1630 6 Canonical, Debian, Linux and 3 more 7 Ubuntu Linux, Debian Linux, Linux Kernel and 4 more 2026-04-23 N/A
The nfs_permission function in fs/nfs/dir.c in the NFS client implementation in the Linux kernel 2.6.29.3 and earlier, when atomic_open is available, does not check execute (aka EXEC or MAY_EXEC) permission bits, which allows local users to bypass permissions and execute files, as demonstrated by files on an NFSv4 fileserver.
CVE-2006-5158 3 Canonical, Linux, Redhat 7 Ubuntu Linux, Linux Kernel, Enterprise Linux and 4 more 2026-04-23 7.5 High
The nlmclnt_mark_reclaim in clntlock.c in NFS lockd in Linux kernel before 2.6.16 allows remote attackers to cause a denial of service (process crash) and deny access to NFS exports via unspecified vectors that trigger a kernel oops (null dereference) and a deadlock.
CVE-2009-2584 1 Linux 1 Linux Kernel 2026-04-23 N/A
Off-by-one error in the options_write function in drivers/misc/sgi-gru/gruprocfs.c in the SGI GRU driver in the Linux kernel 2.6.30.2 and earlier on ia64 and x86 platforms might allow local users to overwrite arbitrary memory locations and gain privileges via a crafted count argument, which triggers a stack-based buffer overflow.
CVE-2007-3642 1 Linux 1 Linux Kernel 2026-04-23 N/A
The decode_choice function in net/netfilter/nf_conntrack_h323_asn1.c in the Linux kernel before 2.6.20.15, 2.6.21.x before 2.6.21.6, and before 2.6.22 allows remote attackers to cause a denial of service (crash) via an encoded, out-of-range index value for a choice field, which triggers a NULL pointer dereference.
CVE-2009-1527 1 Linux 1 Linux Kernel 2026-04-23 N/A
Race condition in the ptrace_attach function in kernel/ptrace.c in the Linux kernel before 2.6.30-rc4 allows local users to gain privileges via a PTRACE_ATTACH ptrace call during an exec system call that is launching a setuid application, related to locking an incorrect cred_exec_mutex object.
CVE-2007-5616 3 Linux, Opengroup, Ssh 4 Linux Kernel, Unix, Tectia Client and 1 more 2026-04-23 N/A
ssh-signer in SSH Tectia Client and Server 5.x before 5.2.4, and 5.3.x before 5.3.6, on Unix and Linux allows local users to gain privileges via unspecified vectors.

CVE-2008-0304 4 Linux, Microsoft, Mozilla and 1 more 5 Linux Kernel, Windows, Seamonkey and 2 more 2026-04-23 N/A
Heap-based buffer overflow in Mozilla Thunderbird before 2.0.0.12 and SeaMonkey before 1.1.8 might allow remote attackers to execute arbitrary code via a crafted external-body MIME type in an e-mail message, related to an incorrect memory allocation during message preview.
CVE-2009-2695 2 Linux, Redhat 4 Linux Kernel, Enterprise Linux, Enterprise Mrg and 1 more 2026-04-23 N/A
The Linux kernel before 2.6.31-rc7 does not properly prevent mmap operations that target page zero and other low memory addresses, which allows local users to gain privileges by exploiting NULL pointer dereference vulnerabilities, related to (1) the default configuration of the allow_unconfined_mmap_low boolean in SELinux on Red Hat Enterprise Linux (RHEL) 5, (2) an error that causes allow_unconfined_mmap_low to be ignored in the unconfined_t domain, (3) lack of a requirement for the CAP_SYS_RAWIO capability for these mmap operations, and (4) interaction between the mmap_min_addr protection mechanism and certain application programs.
CVE-2007-6051 4 Ibm, Linux, Microsoft and 1 more 4 Db2 Universal Database, Linux Kernel, Windows and 1 more 2026-04-23 N/A
IBM DB2 UDB 9.1 before Fixpak 4 assigns incorrect privileges to the (1) DB2ADMNS and (2) DB2USERS alternative groups, which has unknown impact. NOTE: the vendor description of this issue is too vague to be certain that it is security-related.
CVE-2009-4306 1 Linux 1 Linux Kernel 2026-04-23 N/A
Unspecified vulnerability in the EXT4_IOC_MOVE_EXT (aka move extents) ioctl implementation in the ext4 filesystem in the Linux kernel 2.6.32-git6 and earlier allows local users to cause a denial of service (filesystem corruption) via unknown vectors, a different vulnerability than CVE-2009-4131.
