CVE-2026-74455

The CVE-2026-74455 vulnerability in the Linux kernel concerns the peak_usb driver for CAN (uCAN) payloads. pcan_usb_fd_decode_buf() parses multiple CAN records packed in a single USB receive buffer and now requires each record to include the fixed header for its type and validates the CAN payload...

CVE-2026-72466

Summary of CVE-2026-72466 : In the Linux kernel’s xprtrdma implementation, two path issues in rpcrdma_is_bcall() can leak the receive buffer and drain the Receive queue when decoding a reply. The speculative zero-byte peek uses xdr_inline_decode() without respecting xdr->end, allowing five sub...

EUVD-2026-59365

In the Linux kernel, the following vulnerability has been resolved: xprtrdma: Fix bcall rep leak and unbounded peek rpcrdmaisbcall decodes a reply's first words to decide whether the frame is a backchannel call. Two issues in that decode path let a short or malformed reply leak the receive buffer...

CVE-2026-72465 xprtrdma: Sanitize the reply credit grant after parsing

In the Linux kernel, the following vulnerability has been resolved: xprtrdma: Sanitize the reply credit grant after parsing The outnorqst exit in rpcrdmareplyhandler branches away before the credit clamp, so a reply that matches no pending request reaches outpost carrying the raw credit value...

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...

EUVD-2026-55597

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211hwsim: clamp virtio RX length before skbput hwsimvirtiorxwork passes the virtqueue used-ring length reported by the device straight to skbput on a fixed-size receive skb. A backend reporting a length larger than the...

CVE-2026-68135

The CVE-2026-68135 entry concerns the Linux kernel NIC driver hip04, where build_skb() failures in hip04_rx_poll() could bypass the release of the current RX buffer and its DMA mapping, causing resource leaks when a replacement buffer is installed. The fix keeps the current slot intact and return...

CVE-2026-68124 mctp: serial: handle zero-length frames to prevent rx buffer overflow

In the Linux kernel, the following vulnerability has been resolved: mctp: serial: handle zero-length frames to prevent rx buffer overflow The MCTP serial receive state machine reads a frame length byte in mctpserialpushheader case 2 and validates it upper-bound-only: if c MCTPSERIALFRAMEMTU...

CVE-2026-10678 NULL-pointer / out-of-bounds write in Zephyr MCTP I2C+GPIO target binding driven by an unauthenticated I2C controller

The MCTP-over-I2C+GPIO target binding in Zephyr subsys/pmci/mctp/mctpi2cgpiotarget.c processes pseudo-register writes from an I2C bus master byte-by-byte in mctpi2cgpiotargetwritereceived without validating the order or the receive buffer. In the affected versions the MCTPI2CGPIORXMSGADDR data...

SUSE CVE-2026-64125

In the Linux kernel, the following vulnerability has been resolved: net: bcmgenet: keep RBUF EEE/PM disabled Setting RBUFEEEEN | RBUFPMEN in RBUFENERGYCTRL breaks the RX path on GENET hardware once MAC EEE becomes active. RX traffic stops flowing while the link stays up and the usual descriptor/R...

CVE-2026-64081

A flaw was found in the Linux kernel's ARM Firmware Framework for Arm armffa component. This vulnerability arises from insufficient validation of framework notification message layouts. A local attacker, by providing specially crafted firmware data in the shared RX buffer, could trigger an...

CVE-2026-64125

A flaw was found in the Linux kernel's bcmgenet network driver. When Energy Efficient Ethernet EEE is active on GENET hardware, a misconfiguration in the receive buffer RBUF can cause network traffic to stop flowing. This leads to a denial of service for network communications and may result in...

CVE-2026-64177

CVE-2026-64177 is a Linux kernel vulnerability in the Phonet protocol (pep) handling where forwarding of skb to a child socket via sk_receive_skb() incorrectly acquires the child socket lock with BH enabled in the softirq path. The root cause is a BH state mismatch between softirq and process pat...

CVE-2026-64125

In Linux kernel BCMGENET, enabling Energy Efficient Ethernet (EEE) with RBUF_EEE_EN and RBUF_PM_EN breaks RX flow, causing frames to be dropped and rx_packets to stop incrementing; paging faults via bcmgenet_rx_poll have been observed on some hardware (e.g., Pi 4B with BCM2711/BCM54213PE). The is...
