CVE-2026-68135

A flaw was found in the Linux kernel's hip04 network driver. This vulnerability occurs when the buildskb function fails during the hip04rxpoll operation. The driver incorrectly proceeds without releasing the network receive RX buffer and its associated Direct Memory Access DMA mapping. This leads...

CVE-2026-68209

A flaw was found in the Linux kernel's sun4i-csi media driver. When the startstreaming function fails, the vb2 framework does not properly return queued buffers, causing a buffer leak. This issue could lead to resource exhaustion and potentially a Denial of Service DoS condition on the affected...

CVE-2026-68231

A flaw was found in the Linux kernel's media: airspy driver. This vulnerability occurs when the airspystartstreaming function encounters an error, such as a disconnected USB device, and fails to return previously queued buffers. This oversight leads to a resource leak, which can result in a denia...

CVE-2026-68211

A flaw was found in the Linux kernel's stm32-dcmipp media driver. When the startstreaming function fails to initialize, it does not properly return previously queued buffers. This oversight can lead to a leak of these buffers, potentially causing resource exhaustion and affecting system stability...

CVE-2026-68222

A flaw was found in the Linux kernel's msi2500 media driver. This vulnerability occurs when the startstreaming function fails to properly return queued buffers, causing them to leak. An attacker with local access could potentially exploit this to cause system instability or a denial of service Do...

K000162871: PowerDNS DNSdist vulnerability CVE-2026-40211

Security Advisory Description An attacker can send crafted DNS over HTTP/3 queries, triggering an exception that prevents some buffer from being freed right away. The buffer will be freed at the end of the QUIC connection, but on some setups it might be possible to open enough concurrent DoH3...

CVE-2026-68135

In the Linux kernel, the following vulnerability has been resolved: net: hip04: fix RX buffer leak on buildskb failure When buildskb fails in hip04rxpoll, the driver jumps to the refill path without releasing the current RX buffer and its DMA mapping. Installing a replacement buffer then overwrit...
