CVE-2026-46133

A flaw was found in the Linux kernel's Soft RoCE RDMA/rxe driver. An unauthenticated remote attacker can send a specially crafted UDP packet with an unknown opcode to trigger an out-of-bounds read. This vulnerability can lead to a kernel panic, effectively causing a Denial of Service DoS on the...

CVE-2026-46186

A flaw was found in the Linux kernel's virtiobt Bluetooth virtual device driver. An untrusted backend can exploit this vulnerability by sending malformed Bluetooth packets with an insufficient header length. This can cause the system to read uninitialized kernel memory, potentially leading to...

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: netfilter: xt_tcpmss: check remaining length before reading optlen

A flaw was found in the Linux kernel, specifically within the netfilter: xttcpmss module. A remote attacker could exploit this vulnerability by sending a specially crafted TCP packet. The TCP option parser does not properly validate the remaining option length, which results in an out-of-bounds...

Vulnerability of the gdi_CacheToSurface() function in the RDP client FreeRDP, allowing a hacker to execute arbitrary code and cause service failure

The vulnerability of the gdiCacheToSurface function in the RDP client FreeRDP is related to buffer overflow in dynamic memory. Exploiting this vulnerability allows a remote attacker to execute arbitrary code and cause a service failure by sending specially crafted RDPGFX packets...

Elastic Kibana 安全漏洞

Elastic Kibana is a data visualization dashboard software provided by the Elastic company. There is a security vulnerability in Elastic Kibana, which stems from uncontrolled resource consumption. This allows authenticated users with low privileges to submit specially crafted large data packets to...

CVE-2026-45988

A flaw was found in the Linux kernel's rxrpc subsystem. When an rxrpc RESPONSE packet experiences a temporary processing failure, it may enter a partially decrypted state and be re-queued for another attempt. This incorrect handling of partially decrypted packets could lead to communication...

EUVD-2026-32284

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix re-decryption of RESPONSE packets If a RESPONSE packet gets a temporary failure during processing, it may end up in a partially decrypted state - and then get requeued for a retry. Fix this by just discarding the packe...
