kernel: can: raw: fix ro->uniq use-after-free in raw_rcv()

A flaw was found in the Linux kernel's Controller Area Network CAN raw socket implementation. A use-after-free vulnerability can occur due to a timing window during the unregistration of CAN receive filters, allowing a freed memory region to be accessed. This could lead to system instability or a...

kernel: netfilter: nf_conntrack_helper: pass helper to expect cleanup

A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nfconntrackhelper. When a connection tracking helper is unregistered, its associated expectations are not properly cleaned up. This oversight can lead to a use-after-free vulnerability, where the system attempts t...

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: netfilter: ip6t_eui64: reject invalid MAC header for all packets

A flaw was found in the Linux kernel's netfilter component. This vulnerability occurs because the eui64mt6 function, which processes IPv6 packets, does not properly validate the MAC header for all packets. Specifically, packets with a zero fragment offset could bypass an existing guard, allowing...

kernel: net: sched: act_csum: validate nested VLAN headers

A flaw was found in the Linux kernel's network scheduler component. A remote attacker could send specially crafted network packets containing nested Virtual Local Area Network VLAN headers. This could cause the kernel to read beyond allocated memory, leading to a system crash and a denial of...

kernel: Linux kernel: Denial of service and memory corruption in RDMA umad

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA umad User Mode Access Device component. A local user can exploit this vulnerability by manipulating input, causing an integer underflow that leads to an out-of-bounds memory write. This memory corruption can result in a denia...

kernel: Bluetooth: MGMT: Fix possible UAFs

A flaw was found in the Linux kernel’s Bluetooth management subsystem net/bluetooth/mgmt.c. The mgmtpending structure may be freed while still being processed, or remain on the pending command list, which allows a use-after-free or double-free scenario. An attacker with local access to the system...

kernel: HID: wacom: fix out-of-bounds read in wacom_intuos_bt_irq

A flaw was found in the Linux kernel's Wacom Human Interface Device HID driver. This vulnerability allows a remote attacker to trigger an out-of-bounds read by sending a specially crafted, short Bluetooth HID report. This can lead to the disclosure of sensitive information from the system's memor...

CVE-2026-45847

A flaw was found in the Linux kernel's network component, specifically related to handling Internet Protocol over Internet Protocol IPIP tunnels. A local user could potentially craft a network configuration with a very long forward path, which could lead to an unexpected condition within the...

CVE-2026-45848

A flaw was found in the Linux kernel's AppArmor security module. This vulnerability allows a local attacker to trigger a NULL pointer dereference during socket setup or teardown operations. This can lead to a kernel 'oops', resulting in a system crash and a Denial of Service DoS...

CVE-2026-45850

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. A remote attacker could send specially crafted IPv6 packets with extension headers, causing the system to fail protocol checksum validation. This could lead to incorrect packet processing or a denial of service DoS, impactin...

CVE-2026-45849

A flaw was found in the Linux kernel's network component, specifically within the mscc: ocelot driver. The system failed to properly secure access to shared resources during network packet injection, leading to a missing lock protection vulnerability. This oversight could allow a local attacker t...

CVE-2026-45851

A flaw was found in the Linux kernel's Extensible Firmware Interface EFI subsystem. An error in memory reservation for the unaccepted memory table can occur if its starting address is not page-aligned. This vulnerability could lead to the memory table being overwritten or inaccessible, resulting ...

CVE-2026-45854

A flaw was found in the Linux kernel's EIP93 cryptographic accelerator driver. This vulnerability occurs because the driver attempts to unregister all cryptographic algorithms, even those not supported by the hardware. This incorrect handling can lead to a system panic, effectively causing a Deni...

CVE-2026-45853

A flaw was found in the Linux kernel's drm/amdgpu component. The amdgpudiscoverygetnpsinfo function incorrectly deallocates memory by using kfree instead of kvfree, even when memory was allocated with kvcalloc which may use vmalloc. This improper memory handling can lead to memory corruption. Suc...

CVE-2026-45852

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem, specifically within the rxe driver. An error in the rxesrqfrominit function's memory management can lead to a double free vulnerability. This occurs when an attempt to copy data to user space fails, causing the sam...

CVE-2026-45855

A flaw was found in the Linux kernel's libata-scsi component. This vulnerability allows for a denial of service DoS where non-Native Command Queuing NCQ commands can experience significant delays or complete starvation. This occurs when non-NCQ commands are issued while NCQ commands are actively...

CVE-2026-45857

A flaw was found in the Linux kernel's scsi: csiostor module. This null pointer dereference vulnerability occurs in an error handling path. A local attacker could exploit this to cause a system crash, leading to a Denial of Service DoS. Mitigation To prevent exploitation, the csiostor kernel modu...

CVE-2026-45856

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA subsystem, specifically within the ibuverbspostsend function. A local user can exploit this vulnerability by providing an invalid work queue element size wqesize from userspace without proper validation. This can lead to an...

CVE-2026-45858

A flaw was found in the Linux kernel's ext4 filesystem. This vulnerability occurs during the splitting of unwritten data blocks, where a portion of the data may be incorrectly marked as written while still containing stale, uninitialized information. A local attacker could potentially exploit thi...
