CVE-2026-74498

CVE-2026-74498 affects the Linux kernel ALSA USB-audio driver. The vulnerability arises from DMA buffer sizing for full-packet transfers: when fill_max is set, data_ep_set_params() promotes ep->curpacksize to ep->maxpacksize, but maxsize remains the original value derived from the sample ra...

EUVD-2026-59691

In the Linux kernel, the following vulnerability has been resolved: ALSA: usb-audio: Fix DMA buffer out-of-bounds write when fillmax is set When a USB audio endpoint requests full packet transfers via the fillmax descriptor flag, dataepsetparams promotes ep-curpacksize to ep-maxpacksize. However,...

EUVD-2026-59557

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: fix OOB read from firmware RX descriptor exceeding DMA buffer In rtwpcirxnapi, newlen is computed as the sum of pktlen 14-bit descriptor field, max 16383 and pktoffset drvinfosz + shift, both firmware-controlled. The...

CVE-2023-6238 Kernel: nvme: memory corruption via unprivileged user passthrough

A buffer overflow vulnerability was found in the NVM Express NVMe driver in the Linux kernel. Only privileged user could specify a small meta buffer and let the device perform larger Direct Memory Access DMA into the same buffer, overwriting unrelated kernel memory, causing random kernel crashes...

kernel: i2c: out-of-bounds write in xgene_slimpro_i2c_xfer()

An out-of-bounds write vulnerability was found in the Linux kernel's SLIMpro I2C device driver. The userspace "data-block0" variable was not limited to a number between 0-255 and was used as the size of a memcpy, possibly writing beyond the end of dmabuffer. This issue could allow a local...
