CVE-2026-68118

In the Linux kernel, the following vulnerability has been resolved: tcp: challenge ACK for non-exact RST in SYN-RECEIVED The SYN-RECEIVED request-socket path in tcpcheckreq accepts an in-window RST without requiring SEG.SEQ to exactly match RCV.NXT. A non-exact RST therefore removes the request...

CVE-2026-68133

In the Linux kernel, the following vulnerability has been resolved: ice: fix PTP Call Trace during PTP release If a PF reset occurs when the PTP state is ICEPTPUNINIT, then iceptprebuild will update the state to ICEPTPERROR. This will result in the following PTP release call trace during driver...

CVE-2026-68399 bpf: Fix UAF in sock clone early bailouts

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix UAF in sock clone early bailouts Similar to recent commit 9b51a6155d14 "bpf,fork: wipe -bpfstorage before bailouts that access it", skclone performs an initial shallow copy of the socket field -skbpfstorage via sockcopy...

CVE-2026-68374

The CVE-2026-68374 entry concerns the Linux kernel USB core: sysfs bos_descriptors_read(). The root cause is missing synchronization around udev->bos, which can be freed concurrently by usb_reset_and_verify_device() invoked by drivers across the kernel, creating a use-after-free condition. Imp...

EUVD-2026-55560

In the Linux kernel, the following vulnerability has been resolved: usb: core: sysfs: add lock to bosdescriptorsread Add a lock to the function bosdescriptorsread. This function accesses udev-bos, which could be simultaneously freed in usbresetandverifydevice, a function that is commonly called i...

EUVD-2026-55428

In the Linux kernel, the following vulnerability has been resolved: wan: wanxl: Only reset hardware after BAR mapping wanxlpciinitone stores the freshly allocated card in driver data before the PLX BAR is mapped. Several early probe failures then unwind through wanxlpciremoveone, including failur...

CVE-2026-68327 wan: wanxl: Only reset hardware after BAR mapping

In the Linux kernel, the following vulnerability has been resolved: wan: wanxl: Only reset hardware after BAR mapping wanxlpciinitone stores the freshly allocated card in driver data before the PLX BAR is mapped. Several early probe failures then unwind through wanxlpciremoveone, including failur...

CVE-2026-68327

CVE-2026-68327 (wanxl Linux kernel driver): The wanxl PCIe driver resets hardware only after the PLX BAR is mapped. A failure path during probe can call wanxl_reset() while card->plx is NULL, dereferencing MMIO and risking a NULL pointer. The root cause is that wanxl_pci_init_one() stores the ...

CVE-2026-68319 pds_core: fix deadlock between reset thread and remove

In the Linux kernel, the following vulnerability has been resolved: pdscore: fix deadlock between reset thread and remove pciresetfunction acquires devicelock before performing the reset. pdscremove is called by the PCI core with devicelock already held. If pdscpciresetthread is running when...

CVE-2026-68319

The CVE-2026-68319 entry concerns Linux kernel code where a deadlock could occur between the PCI reset thread and removal path. The root cause was that pci_reset_function() acquires device_lock, and pdsc_remove() is invoked with that lock held; if the reset thread is active, destroy_workqueue() b...

CVE-2026-68317 pds_core: fix auxiliary device add/del races

In the Linux kernel, the following vulnerability has been resolved: pdscore: fix auxiliary device add/del races Two paths add or delete the same slot pf-vfsvfid.padev: a VF's pdscresetdone and the PF's devlink enablevnet/disablevnet handler. They serialize on configlock, but neither guards the sl...
