CVE-2026-74306

A flaw was found in the Linux kernel's vfio/qat driver. This vulnerability involves a race condition in the qatvfresumewrite function, where concurrent operations can bypass a critical bounds check. This allows data to be written beyond the intended memory area, potentially corrupting system...

CVE-2026-55648

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.27.0, freerdpimagecopyfromicondata in libfreerdp/codec/color.c calculates nWidth multiplied by nHeight multiplied by FreeRDPGetBytesPerPixelformat in 32-bit arithmetic. A malicious RDP server can send a RAIL TSICONINFO...

CVE-2026-55648

Root cause: In libfreerdp/codec/color.c, freerdp_image_copy_from_icon_data computes nWidth * nHeight * FreeRDPGetBytesPerPixel(format) in 32-bit arithmetic, which wraps for large dimensions (e.g., 32768×32768 at 32 bpp), bypassing the source bounds check before freerdp_image_copy_no_overlap reads...

CVE-2026-55648 FreeRDP: Integer Overflow in `freerdp_image_copy_from_icon_data` Bypasses Bounds Check

CVE-2026-74394

In the Linux kernel, the following vulnerability has been resolved: RDMA/srpt: fix integer overflow in immediate data length check immbuf-len is a user-controlled uint32t received from the network. Adding it to immdataoffset without overflow checking allows a malicious initiator to send...

CVE-2026-74394

In the Linux kernel CVE-2026-74394, RDMA/srpt is affected by an integer overflow in the immediate data length check. The vulnerability occurs because imm_buf->len is a user-controlled uint32_t received from the network, and adding it to imm_data_offset without overflow checking can allow an in...

CVE-2026-68474 powerpc/spufs: fix out-of-bounds access in spufs_mem_mmap_access()

In the Linux kernel, the following vulnerability has been resolved: powerpc/spufs: fix out-of-bounds access in spufsmemmmapaccess spufsmemmmapaccess computes the local store offset as address - vma-vmstart, but bounds-checks it against vma-vmend instead of the local store size. On 64-bit, offset ...

SUSE CVE-2026-16530

A flaw was found in the PCP Performance Co-Pilot pmproxy service. A remote attacker can exploit a vulnerability in the pmLogLoadInDom function by sending a specially crafted request. This bypasses a critical bounds check, which can lead to the pmproxy service crashing, causing a Denial of Service...

CVE-2026-16530

The CVE-2026-16530 entry concerns the PCP (Performance Co-Pilot) pmproxy service. A flaw in the pmLogLoadInDom() function allows a remote attacker to bypass a bounds check, potentially crashing pmproxy (DoS) and, possibly, leaking memory contents. Affected component: pmproxy in PCP. Impact is des...
