Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability that stems from double pointer dereferencing in TPprintk. This can lead to null pointer dereferencing...

Linux Kernel Security Vulnerabilities

The Linux kernel version 5.8 contains a security vulnerability. This vulnerability stems from the regnotnull function in the bpf verifier, which only determines non-NULL based on the register type. There is no limitation on unbounded offsets, resulting in a false positive when the pointer might b...

Linux Kernel Security Vulnerabilities

Security vulnerabilities exist in Linux kernels versions from 5.4.297 to 5.5, from 5.10.231 to 5.11, from 5.15.174 to 5.16, from 6.1.120 to 6.2, from 6.6.64 to 6.7, from 6.11.11 to 6.12, from 6.12.2 to 6.13, and version 6.13. The vulnerability stems from a race condition between hciconndelsysfs a...

ROS-20260924-73-0013

The vulnerability of the devlink component in the Linux operating system’s kernel is related to the dereferencing of a pointer whose expiration time has expired. Exploiting this vulnerability can allow an attacker to trigger a service failure...

ROS-20260924-73-0040

The vulnerability of the fwgetenv function in the arch/mips/fw/lib/cmdline.c file, which is part of the Linux operating system’s MIPS architecture support, involves the dereferencing of pointers. Exploiting this vulnerability can allow an attacker to cause a service failure remotely...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel versions prior to 6.12.111 and prior to 6.18.53. It arises when iwlpcietxinit fails after RX initialization; the freed RX members remain non-NULL. Subsequent cleanup or retry attempts may access these stale RX states, potentially leading to null...

Linux Kernel Security Vulnerabilities

Versions of the Linux kernel prior to 6.18.53 contain security vulnerabilities. These vulnerabilities arise from the IRQ thread acquiring a spinlock between the m2mctx release and the wave5release function removing stream instances from the active instance list. This leads to the reuse of the...

ROS-20260923-73-0071

The vulnerability of the audioreachwidgetloadmodulecommon function in the Linux operating system is related to a pointer dereferencing error. Exploiting this vulnerability could allow an attacker to cause a service failure...

ROS-20260923-73-0088

The vulnerability of the newlockspace function in the fs/dlm/lockspace.c module, which is part of the Linux kernel’s distributed locking manager support, relates to the pointer dereferencing. Exploiting this vulnerability could allow an attacker to trigger a service failure...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability stems from the brcmfmac driver’s improper handling of P2P action frames when a P2P device vif is not created. This could lead to null pointer dereferencing...

Linux Kernel Security Vulnerabilities

The Linux kernel version 5.7 contains a security vulnerability. This vulnerability arises from the incorrect publication of the SCMI transfer channel status before callback activation. Early or false callbacks may dereference empty transfer channel pointers, resulting in null pointer dereferencin...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability arises from incorrect references to session structures in functions nfs4initdssession and fflayoutasynchandleerrorv4, when the NFSv4.0 data server has no sessions. This can lead to null pointer dereferencing...

Linux kernel security vulnerabilities

A security vulnerability exists in Linux kernel version 5.19. It stems from the nvme-apple driver failing to destroy its management queue when being removed, causing timeout timers and work to remain active on queues that are about to be freed. This may lead to null pointer dereferencing and kern...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability stems from NFSv4 passing a NULL parameter priv to nfs4deletelease during the competition between nfs4addlease and delegation reclamation. This allows for null pointer dereferencing in genericsetlease...

Linux kernel security vulnerabilities

A security vulnerability exists in the Linux kernel. It stems from the fact that the serialcoreaddoneport function allocates uport-ttygroups only after uartconfigureport. If this allocation fails, the console remains registered while the port is improperly released, potentially leading to null...

Linux Kernel Security Vulnerabilities

The Linux kernel version 6.7 contains security vulnerabilities. These vulnerabilities stem from race conditions during the process of a dpll device being unmounted. When the last owner unmounts the device, and the external driver still holds a pin, the dpll object remains alive with an empty...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability stems from the fact that the RX bandidx from the 2-bit descriptor field is not verified before being directly used as an index for dev-mt76.phys, resulting in dereferencing of the result. This may lead to out-of-bounds indexing or...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability. This vulnerability stems from the fact that the fsgcommonsetnumbuffers function does not validate the value of n. When the kstrtou8 function interprets n as either 0 or 1, the Kconfig restrictions are bypassed, potentially leading to null pointer...

Linux Kernel Security Vulnerabilities

The Linux kernel has a security vulnerability that stems from the lack of a sanity check after an SCP search fails, which may lead to null pointer dereferencing...

Astra Linux – Vulnerability in libxml2

The vulnerability of the xmlStringGetNodeList function in the tree.c component of the Libxml2 library is related to pointer dereferencing errors. Exploiting this vulnerability could allow an attacker to cause a service failure...
