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

  - drm/i915: Fix request ref counting during error capture & debugfs dump When GuC support was added to error     capture, the reference counting around the request object was broken. Fix it up. The context based search     manages the spinlocking around the search internally. So it needs to grab the reference count internally     as well. The execlist only request based search relies on external locking, so it needs an external     reference count but within the spinlock not outside it. The only other caller of the context based search     is the code for dumping engine state to debugfs. That code wasn't previously getting an explicit reference     at all as it does everything while holding the execlist specific spinlock. So, that needs updaing as well     as that spinlock doesn't help when using GuC submission. Rather than trying to conditionally get/put     depending on submission model, just change it to always do the get/put. v2: Explicitly document adding an     extra blank line in some dense code (Andy Shevchenko). Fix multiple potential null pointer derefs in case     of no request found (some spotted by Tvrtko, but there was more!). Also fix a leaked request in case of     !started and another in __guc_reset_context now that intel_context_find_active_request is actually     reference counting the returned request. v3: Add a _get suffix to intel_context_find_active_request now     that it grabs a reference (Daniele). v4: Split the intel_guc_find_hung_context change to a separate patch     and rename intel_context_find_active_request_get to intel_context_get_active_request (Tvrtko). v5:
    s/locking/reference counting/ in commit message (Tvrtko) (cherry picked from commit     3700e353781e27f1bc7222f51f2cc36cbeb9b4ec) (CVE-2023-52981)

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

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-132 advisory.

    It has been discovered that on some AMD CPUs, the RAS (Return Address Stack, also called RAP - Return     Address Predictor - in some AMD documentation, and RSB - Return Stack Buffer - in Intel terminology) is     dynamically partitioned between non-idle threads.  This allows an attacker to control speculative     execution on the adjacent thread. (CVE-2022-27672)

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

    ovl: Use buf flexible array for memcpy() destination (CVE-2022-49743)

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

    mm/uffd: fix pte marker when fork() without fork event (CVE-2022-49744)

    The upstream bug report describes this issue as follows:

    A flaw found in the Linux Kernel in RDS (Reliable Datagram Sockets) protocol. The     rds_rm_zerocopy_callback() uses list_entry() on the head of a list causing a type confusion. Local user     can trigger this with rds_message_put(). Type confusion leads to `struct rds_msg_zcopy_info *info`     actually points to something else that is potentially controlled by local user. It is known how to trigger     this, which causes an OOB access, and a lock corruption. (CVE-2023-1078)

    A flaw was found in the Framebuffer Console (fbcon) in the Linux Kernel. When providing a font->width and     font->height greater than 32 to the fbcon_set_font, since there are no checks in place, a shift-out-of-     bounds occurs, leading to undefined behavior and possible denial of service. (CVE-2023-3161)

    brcm_nvram_parse in drivers/nvmem/brcm_nvram.c lacks check of the return value of kzalloc() and will cause     the NULL Pointer Dereference (CVE-2023-3359)

    A use-after-free flaw was found in vcs_read in drivers/tty/vt/vc_screen.c in vc_screen in the Linux     Kernel. In this flaw an attacker with local user access may lead to a system crash or a leak of internal     kernel information. (CVE-2023-3567)
