CVE-2026-98641 bpf, arm64: set up the frame pointer for the exception callback

In the Linux kernel, the following vulnerability has been resolved: bpf, arm64: set up the frame pointer for the exception callback A program acting as exception boundary saves all callee-saved registers, so buildprologue takes the exceptioncb path and never calls pushcalleeregs. That is the only...

CVE-2026-98641

The Linux kernel contains a vulnerability affecting BPF on arm64 architectures. The issue arises when a program acts as an exception boundary and saves all callee-saved registers, causing the kernel to fail to correctly set the frame pointer (BPF_REG_FP) for the exception callback. Because the ca...

In the Linux kernel, the following vulnerability has been resolved: HID: amdsfh: Validate PCI BAR size before mapping The amdsfh driver maps PCI BAR 2 using pcimiomapregions and subsequently accesses MMIO registers at offsets up to 0x10958 e.g., AMDP2CMSG3 at 0x1068C. However, the driver never...

CVE-2026-98640 HID: amd_sfh: Validate PCI BAR size before mapping

In the Linux kernel, the following vulnerability has been resolved: HID: amdsfh: Validate PCI BAR size before mapping The amdsfh driver maps PCI BAR 2 using pcimiomapregions and subsequently accesses MMIO registers at offsets up to 0x10958 e.g., AMDP2CMSG3 at 0x1068C. However, the driver never...

CVE-2026-98640

The Linux kernel contains a vulnerability in the amd_sfh driver where it maps PCI BAR 2 using pcim_iomap_regions() without validating if the BAR size is sufficient for subsequent MMIO register accesses (up to offset 0x10958). If the driver binds to a device with a smaller BAR 2, it results in an ...

CVE-2026-98639

The Linux kernel contains a vulnerability in the KVM module related to riscv architecture. The function __kvm_riscv_nacl_hfence() incorrectly writes the Config word before updating the Page_Number and Page_Count words. This violates the SBI v3.0 specification and allows the SBI implementation or ...

CVE-2026-98636

The Linux kernel contains a vulnerability in the squashfs module where mounting an abnormal SquashFS image (with COMP_OPTS set to 1 but a dictionary size of 0) triggers a shift-out-of-bounds error. This occurs because the shift exponent $n$ becomes -1, leading to an invalid shift operation during...
