The version of kernel installed on the remote host is prior to 5.10.269-270.1108. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2026-133 advisory.

    An issue in the Linux kernel's virtio-net/TAP networking path could allow an actor with privileged access     inside a guest virtual machine to send specially crafted network packets that corrupt host kernel memory     on KVM-based hypervisors running unpatched Linux kernel versions 4.4 through 6.18. This could result in     disclosure of host memory or a denial of service.



    In the Linux kernel, the following vulnerability has been resolved:

    netfilter: nf_tables: add hook transactions for device deletions (CVE-2026-63858)

    In the Linux kernel, the following vulnerability has been resolved:

    bpf, skmsg: fix verdict sk_data_ready racing with ktls rx

    sk_psock_strp_data_ready() already checks tls_sw_has_ctx_rx() anddefers to psock->saved_data_ready when a     TLS RX context is present,avoiding a conflict with the TLS strparser's ownership of the receivequeue     (commit e91de6afa81c, bpf: Fix running sk_skb program typeswith ktls).

    sk_psock_verdict_data_ready() has no equivalent guard.  When a socketis inserted into a sockmap     (BPF_SK_SKB_VERDICT) before TLS RX isconfigured, tls_sw_strparser_arm() saves     sk_psock_verdict_data_readyas rx_ctx->saved_data_ready.  On data arrival:

    tls_data_ready -> tls_strp_data_ready -> tls_rx_msg_ready-> saved_data_ready() =     sk_psock_verdict_data_ready()-> tcp_read_skb() drains sk_receive_queue via __skb_unlink()without calling     tcp_eat_skb(), so copied_seq is not advanced.

    tls_strp_msg_load() then finds tcp_inq() >= full_len (stale), callstcp_recv_skb() on the now-empty queue,     hits WARN_ON_ONCE(!first), andreturns with rx_ctx->strp.anchor.frag_list pointing at a psock-     owned(potentially freed) skb.  tls_decrypt_sg() subsequently walks thatfrag_list: use-after-free.

    Apply the same fix as sk_psock_strp_data_ready(): if a TLS RX contextis present, call     psock->saved_data_ready (sock_def_readable) to wakerecv() waiters and return immediately, leaving the     receive queueuntouched.  TLS retains sole ownership of the queue and decrypts therecord normally through     tls_sw_recvmsg(). (CVE-2026-64025)

    USB: iowarrior: fix use-after-free on disconnect race (CVE-2026-64341)

    HID: magicmouse: do not keep a stale msc->input if no input is claimed (CVE-2026-80782)

    In the Linux kernel, the following vulnerability has been resolved:

    ext4: don't enable DAX on new encrypted files (CVE-2026-80806)

    In the Linux kernel, the following vulnerability has been resolved:

    nilfs2: reject invalid block index in GC ioctl (CVE-2026-80807)

    In the Linux kernel, the following vulnerability has been resolved:

    usb: usbfs: fix use-after-free of usb_device in usbdev_release() (CVE-2026-80824)

    In the Linux kernel, the following vulnerability has been resolved:

    USB: serial: option: fix slab OOB read in interrupt URB callback (CVE-2026-80827)

    In the Linux kernel, the following vulnerability has been resolved:

    usb: core: Add lock to usb_wakeup_notification() (CVE-2026-80830)

    In the Linux kernel, the following vulnerability has been resolved:

    ipv6: seg6: clear IPv4 control block on IPIP decapsulation (CVE-2026-80840)

    In the Linux kernel, the following vulnerability has been resolved:

    xfrm: fix xfrm_state_construct() auth-trunc leak (CVE-2026-80843)

    In the Linux kernel, the following vulnerability has been resolved:

    RDMA/rxe: Fix OOB in free_rd_atomic_resources() (CVE-2026-80863)

    In the Linux kernel, the following vulnerability has been resolved: ipv4: validate checksum_start before     completing checksum If a packet with bad checksum metadata gets into the ipv4 stack, skb_checksum_help can     corrupt the network header and cause a bunch of mischief. This was discovered and reported by Paulos, and     has been reporoduced by others independently since. We really shouldn't allow such packets in, but as a     defence in depth measure, let's also check before we complete the checksum. A more complete validation at     input is forthcoming, but needs more work. (CVE-2026-99999)
