CVE-2026-89743

A vulnerability in the Linux kernel's NSM (Network Shared Memory) driver allows a malicious or buggy backend to report a response length larger than the allocated buffer. The function nsm_sendrecv_msg_locked() stores the virtqueue used-ring length without bounding it, so parse_resp_raw() copies e...

CVE-2026-89731

CVE-2026-89731 is an out-of-bounds read in the Linux kernel CXL/RAS subsystem, specifically in the cxl_rch_get_aer_info() function. The function copies the RCH Downstream Port AER capability from the RCRB MMIO block using a readl() loop bounded by sizeof(struct aer_capability_regs). Since struct ...

CVE-2026-89730

CVE-2026-89730 affects the Linux kernel 's altera-cvp FPGA driver. In the function altera_cvp_send_block() , the trailing-byte code path dereferences a u32 pointer even when only 1–3 bytes remain in the input buffer. When the buffer ends at a page or scatterlist boundary, this causes an out-of-bo...
