CVE-2026-43262

CVE-2026-43262 stems from a Linux kernel gfs2 fiemap page fault: gfs2_fiemap() calls iomap_fiemap() while holding the inode glock, risking recursive glock taking if the fiemap buffer maps to the same inode. The fix disables page faults for iomap_fiemap() and faults in the buffer by hand when need...

CVE-2026-43255

The CVE-2026-43255 entry concerns the Linux kernel component for wireless Libertus (wifi: libertas). The vulnerability arises when usb_tx_block() submits cardp->tx_urb without guaranteeing the previous URB has completed; a second call during active URB state can trigger a warning (“URB submitt...
