CVE-2026-99018

The Linux kernel contains a vulnerability under CONFIG_SHADOW_CALL_STACK where the handle_exception() function incorrectly uses the user-writable tp register to determine if a trap originated from userspace. An unprivileged user can manipulate tp to bypass the shadow call stack reload, causing th...

CVE-2026-99018 riscv: entry: gate shadow call stack reload on sstatus.SPP, not tp

In the Linux kernel, the following vulnerability has been resolved: riscv: entry: gate shadow call stack reload on sstatus.SPP, not tp Under CONFIGSHADOWCALLSTACK, handleexception reloads the kernel shadow call stack pointer gp only when the trap came from userspace. It made that decision with...

CVE-2026-99017

The Linux kernel contains a vulnerability where the T-Head C9xx CPU might not have its ghostwrite mitigation applied correctly. The root cause is that errata_probe_ghostwrite() only marks the CPU as vulnerable during the RISCV_ALTERNATIVES_EARLY_BOOT stage. In kernels where ERRATA_THEAD_GHOSTWRIT...

CVE-2026-99016

The Linux kernel contains a vulnerability in the RISC-V architecture's futex implementation. When the tagged address ABI is enabled (CONFIG_RISCV_ISA_SUPM , PMLEN != 0 ), the access_ok() function checks an untagged address, but arch_futex_atomic_op_inuser() and futex_atomic_cmpxchg_inatomic() pas...

CVE-2026-99015

The Linux kernel contains a race condition in the Bluetooth hci_sock component where rebinding an HCI socket after a controller is unregistered can crash the kernel. The root cause is a lack of proper serialization: hci_sock_bind() clears the device reference under only the socket lock, while sen...

CVE-2026-99014

The Linux kernel 's Bluetooth stack is vulnerable to a slab-use-after-free in the hci_sync component during PA sync scan setup . Specifically, hci_le_set_ext_scan_param_sync() retrieves a pointer from hci_sent_cmd_data() without holding a reference to the underlying skb. Because the scan worker a...
