    Several vulnerabilities have been discovered in the Linux kernel that     may lead to a privilege escalation, denial of service or information     leaks.

    For the stable distribution (trixie), these problems have been fixed in     version 6.12.94-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:
    https://security-tracker.debian.org/tracker/linux

Tenable has extracted the preceding description block directly from the EulerOS kernel security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - arm64: io: Extract user memory type in ioremap_prot() The only caller of ioremap_prot() outside of the     generic ioremap() implementation is generic_access_phys(), which passes a 'pgprot_t' value determined from     the user mapping of the target 'pfn' being accessed by the kernel. On arm64, the 'pgprot_t' contains all     of the non-address bits from the pte, including the permission controls, and so we end up returning a new     user mapping from ioremap_prot() which faults when accessed from the kernel on systems with PAN: | Unable     to handle kernel read from unreadable memory at virtual address ffff80008ea89000 | ... | Call trace: |
    __memcpy_fromio+0x80/0xf8 | generic_access_phys+0x20c/0x2b8 | __access_remote_vm+0x46c/0x5b8 |     access_remote_vm+0x18/0x30 | environ_read+0x238/0x3e8 | vfs_read+0xe4/0x2b0 | ksys_read+0xcc/0x178 |
    __arm64_sys_read+0x4c/0x68 Extract only the memory type from the user 'pgprot_t' in ioremap_prot() and     assert that we're being passed a user mapping, to protect us against any changes in future that may     require additional handling. To avoid falsely flagging users of ioremap(), provide our own ioremap() macro     which simply wraps __ioremap_prot(). (CVE-2026-23346)

Note that Nessus relies on the presence of the package as reported by the vendor.
