kernel: KVM: arm64: Take the SRCU lock for page table walks in fault injection and AT emulation

A flaw was found in the Kernel-based Virtual Machine KVM component of the Linux kernel on arm64 architectures. This vulnerability occurs because certain page table walk operations, used in fault injection and Address Translation AT emulation, do not properly acquire a Sleepable Read-Copy Update...

SUSE CVE-2026-80869

In the Linux kernel, the following vulnerability has been resolved: ntfs: bound the attribute-list entry in ntfsreadinodemount The $MFT attribute-list walk in ntfsreadinodemount validates each entry only with "u8 alentry + 6 alend" and "u8 alentry + le16tocpualentry-length alend", but then reads...

CVE-2026-80869

CVE-2026-80869 affects the Linux kernel NTFS filesystem driver. In ntfs_read_inode_mount() , the $MFT attribute-list walk validated only that 6 bytes of each entry were in range, then read lowest_vcn (offset 8, 8 bytes) and mft_reference (offset 16) — fields beyond the proven boundary. Since al_e...

CVE-2026-80800

CVE-2026-80800 affects the Linux kernel NFC LLCP subsystem. The function nfc_llcp_connect_sn() walks a TLV list without validating that the two-byte header or declared length stay within the skb buffer, and computes tlv_array_len as skb->len - LLCP_HEADER_SIZE in size_t, causing an underflow f...

kernel: netfilter: nf_tables: don't skip expired elements during walk

A flaw was found in the Linux kernel. Improper management of the lifecycle of some nftables objects could result in consumption of all system memory. An attacker who can create nftables rules could use this to effect a Denial of Service...

The remote RockyLinux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RLSA-2026:59723 advisory. kernel: ksm: use range-walk function to jump over holes in scangetnextrmapitem CVE-2025-68211 kernel: ip6tunnel: use skbvlaninetprepare in ip6tnlrcv...

kernel: ksm: use range-walk function to jump over holes in scan_get_next_rmap_item

A resource exhaustion vulnerability was found in the Kernel Same-page Merging KSM subsystem of the Linux kernel. When scanning processes with large sparse virtual memory mappings e.g., 32 TiB with one mapped page, ksmd inefficiently walks every address rather than skipping unmapped holes. This...
