CVE-2026-74681 usb: misc: usbio: check ibuf_len against rxbuf_len in bulk msg

In the Linux kernel, the following vulnerability has been resolved: usb: misc: usbio: check ibuflen against rxbuflen in bulk msg ibuflen is the bulk IN receive buffer size, but the EMSGSIZE check in usbiobulkmsg compares it against txbuflen — the bulk OUT endpoint size. Both are taken independent...

Linux Distros Unpatched Vulnerability : CVE-2026-74681

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - usb: misc: usbio: check ibuflen against rxbuflen in bulk msg ibuflen is the bulk IN receive buffer size, but the EMSGSIZE check in usbiobulkmsg compares it...

CVE-2026-75900

An out-of-bounds read vulnerability was found in swtpm's SWTPMNVRAMCheckHeader function. The entry guard checks the buffer length against sizeofbh, where bh is a pointer, instead of sizeofbh, the actual struct size. This allows an undersized buffer to pass validation, causing a 2-byte heap overre...

CVE-2026-68184

A flaw was found in the Linux kernel's CD-ROM cdrom driver. When handling the CDROMVOLCTRL command, the mmcioctlcdromvolume function can perform an incorrect calculation of buffer length after a pointer adjustment. This leads to a stack out-of-bounds read, where 8 bytes of data beyond the intende...

CVE-2026-68353

In the Linux kernel, the following vulnerability has been resolved: wifi: ath6kl: fix OOB read from firmware nummsg in TX complete handler The firmware-controlled nummsg field u8, 0-255 drives the loop in ath6klwmitxcompleteeventrx without validation against the buffer length. This allows...

CVE-2026-68184

In the Linux kernel, the following vulnerability has been resolved: cdrom: fix stack out-of-bounds read in CDROMVOLCTRL mmcioctlcdromvolume first reads the audio control mode page into a 32-byte stack buffer with cgc-buflen set to 24. If the device reports a block descriptor, the function increas...

CVE-2026-68088

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: function: rndis: add length check to response query Add variable representations for BufLength and BufOffset in rndisqueryresponse, and perform a length check on them. This is identical to how rndissetresponse handle...

CVE-2026-68352

CVE-2026-68352 concerns the Linux kernel’s ath6kl Wi‑Fi driver. The vulnerability arises from insufficient validation of firmware‑controlled IE lengths (beacon_ie_len, assoc_req_len, assoc_resp_len) in ath6kl_wmi_connect_event_rx(), allowing a total IE length up to 765 to exceed the actual WMI ev...

CVE-2026-68196 wifi: wilc1000: validate assoc response length before subtracting header

In the Linux kernel, the following vulnerability has been resolved: wifi: wilc1000: validate assoc response length before subtracting header wilcparseassocrespinfo computes the trailing IE length as ieslen = bufferlen - sizeofres; without first checking that bufferlen is at least sizeofstruct...

CVE-2026-68184

The CVE-2026-68184 issue affects the Linux kernel CD-ROM code, specifically mmc_ioctl_cdrom_volume for CDROMVOLCTRL. A 32-byte stack buffer is used to read the audio control mode page (buflen 24, then extended if a block descriptor is present). The function later builds a MODE SELECT payload by m...

CVE-2026-68088

The CVE describes a Linux kernel usb gadget rndis vulnerability where the rndis_query_response() path now validates BufLength and BufOffset (introducing a length check) to match the handling in rndis_set_response(). The vulnerability affects the rndis function of the USB gadget subsystem in the L...
