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...

In the Linux kernel, the following vulnerability has been resolved: ocfs2: validate directory-index entry counts when reading metadata ocfs2validatedxleaf and ocfs2validatedxroot check the ECC and signature of an indexed-directory block before it reaches higher-level callers, but neither validato...

CVE-2026-89488

In the Linux kernel, the following vulnerability has been resolved: openvswitch: Fix CT limit teardown use-after-free Packet processing uses CT limit state under RCU, while netns teardown frees that state under ovsmutex. The CT limit pointer was neither removed from readers nor protected by a gra...

CVE-2026-89488

CVE-2026-89488 is a slab-use-after-free in the Linux kernel's Open vSwitch (OVS) component, occurring during network namespace teardown . Packet processing reads CT (connection tracking) limit state under RCU, while teardown frees that state under ovs_mutex without removing the pointer from reade...

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...

CVE-2026-81008

CVE-2026-81008 is a slab use-after-free in the Linux kernel's interconnect subsystem, affecting icc_get() and of_icc_get_by_index(). When kasprintf() fails to allocate path->name, the error path calls kfree(path) directly, leaving dangling pointers in the req_list hlists that were already popu...

CVE-2026-81002

CVE-2026-81002 is a critical (CVSS 9.8) memory corruption flaw in the Linux kernel's XDP component. The xdp_convert_zc_to_xdp_frame() function clones an AF_XDP zero-copy packet into an order-0 page but incorrectly advertises PAGE_SIZE as the frame size, allowing the frame to overlap skb_shared_in...
