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 there is no data buffer that gets written out. If this bit is set using commands like "sg_write_same --ndob" we will crash in target_core_iblock/file's execute_write_same handlers when we go to access the se_cmd->t_data_sg because its NULL. This patch adds a check for the NDOB bit in the common WRITE SAME code because we don't support it. And, it adds a check for zero SG elements in each handler in case the initiator tries to send a normal WRITE SAME with no data buffer.

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.

    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().

The remote OracleVM system is missing necessary patches to address security updates:

  - In the Linux kernel before 4.20.14, expand_downwards in mm/mmap.c lacks a check for the mmap minimum     address, which makes it easier for attackers to exploit kernel NULL pointer dereferences on non-SMAP     platforms. This is related to a capability check for the wrong task. (CVE-2019-9213)

  - An issue was discovered in the Linux kernel through 5.16.11. The mixed IPID assignment method with the     hash-based IPID assignment policy allows an off-path attacker to inject data into a victim's TCP session     or terminate that session. (CVE-2020-36516)

  - A race condition in the Linux kernel before 5.6.2 between the VT_DISALLOCATE ioctl and closing/opening of     ttys could lead to a use-after-free. (CVE-2020-36557)

  - A race condition in the Linux kernel before 5.5.7 involving VT_RESIZEX could lead to a NULL pointer     dereference and general protection fault. (CVE-2020-36558)

  - When sending malicous data to kernel by ioctl cmd FBIOPUT_VSCREENINFO,kernel will write memory out of     bounds. (CVE-2021-33655)

  - When setting font with malicous data by ioctl cmd PIO_FONT,kernel will write memory out of bounds.
    (CVE-2021-33656)

  - A use-after-free flaw was found in the Linux kernel's FUSE filesystem in the way a user triggers write().
    This flaw allows a local user to gain unauthorized access to data from the FUSE filesystem, resulting in     privilege escalation. (CVE-2022-1011)
