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-2026-89489

CVE-2026-89489 affects the Linux kernel on the openrisc (or1k) architecture. The sys_or1k_atomic() syscall (number 244) swaps two user-supplied words via hand-written assembly without validating the pointers with access_ok() and without exception table entries for the four memory accesses. An unp...

CVE-2026-89487

CVE-2026-89487 affects the openvswitch subsystem in the Linux kernel. The bug resides in queue_userspace_packet(), whose error path calls skb_tx_error() on a packet that is still being forwarded through remaining flow actions. This call strips SKBFL_SHARED_FRAG from the live skb via skb_zcopy_cle...
