CVE-2026-89492

CVE-2026-89492 is a slab out-of-bounds read in the Linux kernel's OCFS2 filesystem. The functions ocfs2_validate_dx_leaf() and ocfs2_validate_dx_root() fail to bound the ocfs2_dx_entry_list counts against the 4 KB block capacity. As a result, ocfs2_dx_dir_search() can walk up to 0xffff entries pa...

CVE-2026-89493

CVE-2026-89493 is an out-of-bounds read/write in the Linux kernel's OCFS2 filesystem module. The root cause is that ocfs2_validate_refcount_block() never validates rl_used and rl_count against the block's fixed on-disk capacity (247 records in a 4K block). A crafted or corrupted refcount block wi...

CVE-2026-89471

CVE-2026-89471 affects the Linux kernel cros_usbpd-charger driver (power supply subsystem). The driver uses an EC-reported num_charger_ports value as a loop bound for an 8-entry fixed-size array (ports[EC_USB_PD_MAX_PORTS]) without validating it against the array size. A malicious or malfunctioni...
