SUSE CVE-2023-52476

In the Linux kernel, the following vulnerability has been resolved: perf/x86/lbr: Filter vsyscall addresses We found that a panic can occur when a vsyscall is made while LBR sampling is active. If the vsyscall is interrupted NMI for perf sampling, this call sequence can occur most recent at top:...

CVE-2024-26596 net: dsa: fix netdev_priv() dereference before check on non-DSA netdevice events

In the Linux kernel, the following vulnerability has been resolved: net: dsa: fix netdevpriv dereference before check on non-DSA netdevice events After the blamed commit, we started doing this dereference for every NETDEVCHANGEUPPER and NETDEVPRECHANGEUPPER event in the system. static inline stru...

kernel: ALSA: ymfpci: Create card with device-managed snd_devm_card_new()

A flaw was found in the Linux kernel's ALSA ymfpci sound driver. During a previous refactoring commit that removed sndcardymfpciremove, the sndcardnew call was not updated to snddevmcardnew. This omission means sndcardfree is never called during module unload, leading to a kernel oops when...

kernel: cifs: fix oops during encryption

An out-of-bounds memory access vulnerability exists in the linux kernel, such that A stack-allocated buffer backed by vmalloc was passed into crypto code scatterwalkmapandcopy → memcpy where a cross-page write occurred. This ended up hitting a read-only mapping, causing a page-level fault and...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the Linux kernel's net/mlx5 component related to the handling of E-switch pairing during uplink un/load APIs. Specifically, when transitioning a device from switchdev mo...

SUSE CVE-2005-2099

The Linux kernel before 2.6.12.5 does not properly destroy a keyring that is not instantiated properly, which allows local users or remote attackers to cause a denial of service kernel oops via a keyring with a payload that is not empty, which causes the creation to fail, leading to a null...

SUSE CVE-2005-2709

The sysctl functionality sysctl.c in Linux kernel before 2.6.14.1 allows local users to cause a denial of service kernel oops and possibly execute code by opening an interface file in /proc/sys/net/ipv4/conf/, waiting until the interface is unregistered, then obtaining and modifying function...

SUSE CVE-2006-5158

The nlmclntmarkreclaim 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...

SUSE CVE-2007-0773

The Linux kernel before 2.6.9-42.0.8 in Red Hat 4.4 allows local users to cause a denial of service kernel OOPS from null dereference via fput in a 32-bit ioctl on 64-bit x86 systems, an incomplete fix of CVE-2005-3044.1...

SUSE CVE-2008-3686

The rt6fillnode function in net/ipv6/route.c in Linux kernel 2.6.26-rc4, 2.6.26.2, and possibly other 2.6.26 versions, allows local users to cause a denial of service kernel OOPS via IPv6 requests when no IPv6 input device is in use, which triggers a NULL pointer dereference...

SUSE CVE-2010-2243

A vulnerability exists in kernel/time/clocksource.c in the Linux kernel before 2.6.34 where on non-GENERICTIME systems GENERICTIME=n, accessing /sys/devices/system/clocksource/clocksource0/currentclocksource results in an OOPS...

SUSE CVE-2011-4110

The userupdate function in security/keys/userdefined.c in the Linux kernel 2.6 allows local users to cause a denial of service NULL pointer dereference and kernel oops via vectors related to a user-defined key and "updating a negative key into a fully instantiated key."...

SUSE CVE-2011-4132

The cleanupjournaltail function in the Journaling Block Device JBD functionality in the Linux kernel 2.6 allows local users to cause a denial of service assertion error and kernel oops via an ext3 or ext4 image with an "invalid log first block value."...

SUSE CVE-2014-5077

The sctpassocupdate function in net/sctp/associola.c in the Linux kernel through 3.15.8, when SCTP authentication is enabled, allows remote attackers to cause a denial of service NULL pointer dereference and OOPS by starting to establish an association between two endpoints immediately after an...

SUSE CVE-2017-8797

The NFSv4 server in the Linux kernel before 4.11.3 does not properly validate the layout type when processing the NFSv4 pNFS GETDEVICEINFO or LAYOUTGET operand in a UDP packet from a remote attacker. This type value is uninitialized upon encountering certain error conditions. This value is used a...

Exploiting null-dereferences in the Linux kernel

Posted by Seth Jenkins, Project Zero For a fair amount of time, null-deref bugs were a highly exploitable kernel bug class. Back when the kernel was able to access userland memory without restriction, and userland programs were still able to map the zero page, there were many easy techniques for...
