CVE-2026-90263

CVE-2026-90263 affects the Linux kernel's btrfs filesystem . When the btrfs read-only property is set to true, all write operations including ACL and xattr should be denied. However, POSIX ACLs could still be set because a prior commit (353c2ea735e4) removed a readonly-root check from btrfs_setxa...

EUVD-2026-81856

In the Linux kernel, the following vulnerability has been resolved: btrfs: check if root is readonly when setting posix acl For a filesystem which has btrfs read-only property set to true, all write operations including acl and xattr should be denied. However, acl can still be set even if btrfs r...

CVE-2026-90227 nvme/ioctl: check SUBMIT_IO with nvme_cmd_allowed()

In the Linux kernel, the following vulnerability has been resolved: nvme/ioctl: check SUBMITIO with nvmecmdallowed Unlike IOCMD / IO64CMD, NVMEIOCTLSUBMITIO never calls nvmecmdallowed. Unprivileged callers can thus issue I/O on a partition device or write through a read-only file descriptor. Pass...

CVE-2026-90177 bpf: Check pointer type for all atomic RMW paths

In the Linux kernel, the following vulnerability has been resolved: bpf: Check pointer type for all atomic RMW paths Atomic RMW verification records an instruction pointer type only when the current destination is PTRTOARENA. A second path can therefore reach the same instruction with an ordinary...

CVE-2026-90176

This vulnerability affects the Linux kernel's ksmbd (in-kernel SMB/CIFS server) component. The function check_lock_range() uses inclusive ranges , so start == end represents a valid single-byte range. However, a shortcut incorrectly treats this case as an empty range, skipping mandatory byte-rang...

EUVD-2026-81769

In the Linux kernel, the following vulnerability has been resolved: ksmbd: Do not skip lock checks for single-byte ranges checklockrange uses inclusive ranges. Its callers pass the end offset as start + length - 1, so start == end represents a valid single-byte range rather than an empty range. T...

EUVD-2026-81753

In the Linux kernel, the following vulnerability has been resolved: lwtbpf: Restore reserved headroom after xmit program ipfinishoutput2 expands an skb to LLRESERVEDSPACEdev before LWT xmit. An LWTXMIT BPF program can then modify the skb head and still return BPFOK, so bpfxmit rechecks the...

CVE-2026-90146

CVE-2026-90146 is a Linux kernel vulnerability in the BPF/XDP subsystem. The root cause is that bpf_xdp_link_update() calls dev_xdp_install() directly, bypassing the validation checks in dev_xdp_attach(). This allows a local user with low privileges to create an XDP link with a normal program and...
