CVE-2026-80697

CVE-2026-80697 affects the Linux kernel in the erofs (Enhanced Read-Only Filesystem) subsystem. Backing files for page cache sharing were previously set up with f_path left as NULL (only f_inode was valid). A recent mincore fix relies on f_path.mnt, triggering a kernel NULL pointer dereference an...

CVE-2026-80697 erofs: ensure valid f_path for page cache sharing

In the Linux kernel, the following vulnerability has been resolved: erofs: ensure valid fpath for page cache sharing Previously, backing files for page cache sharing were set up with fpath left as NULL only finode was valid. It worked, but a recent mincore fix relies on fpath.mnt and crashes foun...

CVE-2026-80688

CVE-2026-80688 affects the Linux kernel on the RISC-V architecture. The vulnerable component is the function vec_check_unaligned_access_speed_all_cpus, which carries an __init annotation but executes within a kthread . If the SBI calls it makes are slow (e.g., due to debug output), the kthread ma...

CVE-2026-80688 riscv: drop __init from vec_check_unaligned_access_speed_all_cpus

In the Linux kernel, the following vulnerability has been resolved: riscv: drop init from veccheckunalignedaccessspeedallcpus This function runs within a kthread and need not necessarily finish before system finishes boot and freeinitmem unmaps the .init.text section.

CVE-2026-80685

A Linux kernel vulnerability in the snapshot_page() function within mm/util causes an out-of-bounds read of the __page_2 field for order-1 folios allocated at the end of a vmemmap section . The function incorrectly reads __page_2 when nr_pages > 1, but should only do so when nr_pages > 2; s...

CVE-2026-80682

CVE-2026-80682 is a unit mismatch bug in the Linux kernel 's RISC-V memory management subsystem (riscv/mm). When computing vmemmap_start_pfn, the kernel fed MAX_FOLIO_VMEMMAP_ALIGN (measured in bytes of struct page storage) directly into VMEMMAP_ADDR_ALIGN, which operates in the physical-address ...
