In the Linux kernel, the following vulnerability has been resolved: smb/server: fix potential null-ptr-deref of lease_ctx_info in smb2_open() null-ptr-deref will occur when (req_op_level == SMB2_OPLOCK_LEVEL_LEASE) and parse_lease_state() return NULL. Fix this by check if 'lease_ctx_info' is NULL. Additionally, remove the redundant parentheses in parse_durable_handle_context().

The version of kernel installed on the remote host is prior to 5.15.184-125.190. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2025-073 advisory.

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

    scsi: target: Fix WRITE_SAME No Data Buffer crash

    In newer version of the SBC specs, we have a NDOB bit that indicates thereis no data buffer that gets     written out. If this bit is set using commandslike sg_write_same --ndob we will crash in     target_core_iblock/file'sexecute_write_same handlers when we go to access the se_cmd->t_data_sgbecause its     NULL.

    This patch adds a check for the NDOB bit in the common WRITE SAME codebecause we don't support it. And, it     adds a check for zero SG elements ineach handler in case the initiator tries to send a normal WRITE SAME     withno data buffer. (CVE-2022-21546)

    ipv6: release nexthop on device removal

    The CI is hitting some aperiodic hangup at device removal time in thepmtu.sh self-test:

    While the first suspect is the dst_cache, explicitly tracking the dstowing the last device reference via     probes proved such dst is held bythe nexthop in the originating fib6_info.

    Similar to commit f5b51fe804ec (ipv6: route: purge exception onremoval), we need to explicitly release     the originating fib info whendisconnecting a to-be-removed device from a live ipv6 dst: move thefib6_info     cleanup into ip6_dst_ifdown().

    Tested running:

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

    For Debian 11 bullseye, these problems have been fixed in version     6.1.137-1~deb11u1.  This additionally includes many more bug fixes     from stable updates 6.1.130-6.1.137 and an update of the Microsoft     Azure Network Adapter (mana) driver.

    We recommend that you upgrade your linux-6.1 packages.

    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 (bookworm), these problems have been fixed in     version 6.1.135-1.

    We recommend that you upgrade your linux packages.

    For the detailed security status of linux please refer to its security     tracker page at:

Tenable has extracted the preceding description block directly from the Debian 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.

  - In the Linux kernel, the following vulnerability has been resolved: smb/server: fix potential null-ptr-     deref of lease_ctx_info in smb2_open() null-ptr-deref will occur when (req_op_level ==     SMB2_OPLOCK_LEVEL_LEASE) and parse_lease_state() return NULL. Fix this by check if 'lease_ctx_info' is     NULL. Additionally, remove the redundant parentheses in parse_durable_handle_context(). (CVE-2024-46742)

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