CVE-2026-46258

A flaw was found in the Linux kernel's gpio: cdev module. A NULL pointer dereference in the linehandlecreate function can occur, leading to a system crash. This vulnerability could allow a local attacker to cause a Denial of Service DoS...

CVE-2026-46245

A flaw was found in the Linux kernel's AMD GPU display driver. The amdgpudmhpdinit function, responsible for Hot-Plug Detect HPD initialization, may attempt to dereference a null dclink when handling certain connectors. This unconditional dereference can lead to a system crash, allowing a local...

CVE-2026-46260

A flaw was found in the Linux kernel's IPv6 networking subsystem. This vulnerability, an out-of-bound read, occurs during the creation of an IPv6 route with specific parameters. A local attacker could exploit this flaw to cause memory corruption, potentially leading to system instability or a...

CVE-2026-46273

A flaw was found in the Linux kernel's ibmveth driver. This vulnerability occurs when physical adapters on Power systems attempt to perform Generic Segmentation Offload GSO with a Maximum Segment Size MSS less than 224 bytes. A remote attacker could exploit this by sending specially crafted netwo...

CVE-2026-46250

A flaw was found in the Linux kernel, specifically affecting the MIPS architecture when compiled with LLVM. This vulnerability occurs because LLVM incorrectly restores the $gp register, which is used as a global register variable, after it has been intentionally modified during kernel relocation...

CVE-2026-46271

A flaw was found in the Linux kernel's ath12k Wi-Fi driver. When a multi-link connection is active, the firmware incorrectly enables Wake-on-Wireless WoW offloads on both primary and secondary links. This misconfiguration can lead to a firmware crash on WCN7850 devices, resulting in a Denial of...

CVE-2026-46244

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nftinner module. This vulnerability arises from an incorrect handling of IPv6 inner packet processing, where the transport header offset innerthoff becomes desynchronized from the Layer 4 protocol l4proto. A remot...

CVE-2026-46262

A flaw was found in the Linux kernel's audio subsystem, specifically in the fslxcvr module. This vulnerability allows a local user to trigger a deadlock condition within the system. By attempting to acquire a read lock while already holding a write lock in the same process, the system can become...

CVE-2026-46270

A flaw was found in the Linux kernel's power supply driver, specifically in the rt9455 component. This vulnerability, a use-after-free, occurs due to a race condition during the system's shutdown process where an interrupt can access memory that has already been released. This can lead to system...

CVE-2026-46269

A flaw was found in the Linux kernel's k230 pinctrl driver. During the probing process, a NULL pointer dereference can occur when parsing the devicetree. This vulnerability allows a local attacker to trigger a system crash, leading to a Denial of Service DoS. The issue arises from attempting to...

CVE-2026-46266

A flaw was found in the Linux kernel's handling of RAW sockets using IPPROTORAW. A remote attacker could send a specially crafted ICMP Internet Control Message Protocol packet. This malicious packet could set the protocol field to 255, causing it to be processed by a RAW socket configured for...

CVE-2026-46256

A flaw was found in the Linux kernel, specifically within the NFS Network File System LOCALIO optimization. This vulnerability allows for a recursion deadlock to occur during direct reclaim operations. When LOCALIO attempts to write pages back into NFS via nfswritepages, it can lead to a system...

kernel: smb: client: validate the whole DACL before rewriting it in cifsacl

A flaw was found in the Linux kernel's Server Message Block SMB client, specifically within the cifsacl functionality. A malicious SMB server could provide a malformed Discretionary Access Control List DACL that claims to contain more Access Control Entries ACEs than are actually present. This...

kernel: Linux kernel: Use-after-free in traffic control (act_ct) may lead to denial of service or privilege escalation

A flaw was found in the Linux kernel. A use-after-free vulnerability exists in the traffic control actct path when it is incorrectly configured with non-ingress egress qdiscs queueing disciplines. This can allow a local user with specific privileges to trigger a kernel crash, leading to a denial ...

kernel: ipv6: icmp: clear skb2->cb[] in ip6_err_gen_icmpv6_unreach()

A flaw was found in the Linux kernel's IPv6 ICMP error generation. A remote attacker could send a specially crafted IPv4 ICMP error packet with a Common Internet Protocol Security Option CIPSO IP option. This could lead to incorrect handling of packet control block data when generating an IPv6 IC...

kernel: Linux kernel: Use-after-free in bonding driver leads to denial of service

A flaw was found in the Linux kernel's bonding driver. A local attacker with low privileges could exploit a use-after-free vulnerability in the bondxmitbroadcast function. This occurs due to a race condition during concurrent slave enslave/release operations, which can lead to the original socket...

CVE-2026-46252

A flaw was found in the Linux kernel's regulator core. Incorrect handling of locking in the regulatorresolvesupply function's error path can trigger a lockdep warning. This issue may allow for concurrent access problems, potentially leading to system instability or a denial of service DoS conditi...

CVE-2026-46264

A flaw was found in the Linux kernel's drm/xe/pf component. This vulnerability arises during the initialization of the sysfs interface, where an error in devmaddactionorreset can cause a cleanup action to execute on an uninitialized kernel object. This can lead to a use-after-free condition, whic...
