kernel: wifi: mac80211: remove station if connection prep fails

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. When Multi-Link Operation MLO connection preparation fails, the system may not correctly remove the associated station. This can lead to a use-after-free or double-free vulnerability in the debugfs component, potentially causing...

kernel: netfilter: flowtable: strictly check for maximum number of actions

A flaw was found in the Netfilter flowtable component of the Linux kernel. This vulnerability occurs because the system does not strictly check the maximum number of hardware offload actions for IPv6, allowing it to process more actions than supported. This could potentially lead to system...

CVE-2026-46330

In the Linux kernel, the following vulnerability has been resolved: Revert "net/smc: Introduce TCP ULP support" This reverts commit d7cd421da9da2cc7b4d25b8537f66db5c8331c40. As reported by Al Viro, the TCP ULP support for SMC is fundamentally broken. The implementation attempts to convert an acti...

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from design flaws in the TCP ULP support implemented in the net/smc module. This vulnerability allows an...

PT-2026-47788

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description TCP ULP support for SMC is fundamentally broken. The implementation attempts to convert an active TCP socket into an SMC socket by modifying the underlying struct file, dentry, and inode...

CVE-2026-46311

A flaw was found in the Linux kernel. This vulnerability, located in the drm/amdgpu/userq component, involves improper handling of memory mappings. A local attacker could potentially exploit a race condition during queue creation, where a memory object is unmapped while another is being assigned ...

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-2026-46267

A flaw was found in the Linux kernel's Near Field Communication NFC Host Controller Interface HCI Synchronous High-level Data Link Control SHDLC subsystem. This vulnerability arises because timers and work items can remain active and access freed SHDLC state and data queues during the...

CVE-2026-46128

A flaw was found in the Linux kernel's Intelligent Platform Management Interface IPMI subsystem. This vulnerability occurs when the kernel processes event message buffer responses from Baseboard Management Controllers BMCs. Some BMCs may return an empty message instead of an expected error, which...

CVE-2026-46204

A flaw was found in the Linux kernel's AMD GPU Graphics Processing Unit driver, specifically within the drm/amdgpu/vcn4 component. This vulnerability allows for an out-of-bounds read when processing an Instruction Buffer IB. An attacker could potentially exploit this to read sensitive information...

CVE-2026-46208

A flaw was found in the Linux kernel's batman-adv module. When a mesh interface is removed, the batadvmeshfree function does not properly stop tpmeter sessions. This oversight allows active tpmeter sender threads or late incoming packets to continue processing against a mesh instance that is in t...

CVE-2026-46210

A flaw was found in the Linux kernel's iris media driver. A race condition can occur when the driver attempts to free a resource while it is still being accessed by another part of the system. This leads to a use-after-free vulnerability, where a program tries to use memory that has already been...

CVE-2026-46217

A flaw was found in the Linux kernel, specifically within the AMD GPU Graphics Processing Unit driver component drm/amdgpu/vcn4. This vulnerability is caused by an integer overflow during a message bound check. An attacker could potentially exploit this flaw to cause system instability or a denia...

CVE-2026-46115

A flaw was found in the Linux kernel's block subsystem. The biovecphysmergeable function, which combines physically contiguous memory segments, lacked a check to ensure these segments belonged to the same device page map devpagemap. This omission could result in the incorrect identification of th...

CVE-2026-46174

A flaw was found in the Linux kernel, specifically within the x86/CPU/AMD Zen2's op cache. This vulnerability arises from improper isolation of shared resources, which can lead to instruction corruption. The consequence of this flaw is that it may cause unexpected behavior or instability within t...

CVE-2026-45893

A flaw was found in the Linux kernel's AppArmor security module. This vulnerability occurs when AppArmor attempts to create tables from user-provided data that may be unaligned in memory. A local attacker could exploit this by providing specially crafted input, leading to unaligned memory accesse...

CVE-2026-45913
