In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix potential null dereference The adev->dm.dc pointer can be NULL and dereferenced in amdgpu_dm_fini() without checking. Add a NULL pointer check before calling dc_dmub_srv_destroy(). Found by Linux Verification Center (linuxtesting.org) with SVACE.

The AlmaLinux 9.2 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare ALMALINUX9.2:CLSA-2026:1777616064 advisory.

  - In the Linux kernel, the following vulnerability has been resolved: tracing: Fix potential double free in     create_var_ref() In create_var_ref(), init_var_ref() is called to initialize the fields of variable     ref_field, which is allocated in the previous function call to create_hist_field(). Function     init_var_ref() allocates the corresponding fields such as ref_field->system, but frees these fields when     the function encounters an error. The caller later calls destroy_hist_field() to conduct error handling,     which frees the fields and the variable itself. This results in double free of the fields which are     already freed in the previous function. Fix this by storing NULL to the corresponding fields when they are     freed in init_var_ref(). (CVE-2022-49410)

  - In the Linux kernel, the following vulnerability has been resolved: net: mdio: fix undefined behavior in     bit shift for __mdiobus_register Shifting signed 32-bit value by 31 bits is undefined, so changing     significant bit to unsigned. The UBSAN warning calltrace like below: UBSAN: shift-out-of-bounds in     drivers/net/phy/mdio_bus.c:586:27 left shift of 1 by 31 places cannot be represented in type 'int' Call     Trace: <TASK> dump_stack_lvl+0x7d/0xa5 dump_stack+0x15/0x1b ubsan_epilogue+0xe/0x4e

  - In the Linux kernel, the following vulnerability has been resolved: vt: Clear selection before changing     the font When changing the console font with ioctl(KDFONTOP) the new font size can be bigger than the     previous font. A previous selection may thus now be outside of the new screen size and thus trigger out-     of-bounds accesses to graphics memory if the selection is removed in vc_do_resize(). Prevent such out-of-     memory accesses by dropping the selection before the various con_font_set() console handlers are called.
    (CVE-2022-49948)

  - In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: fix double free on     tx path. We see kernel crashes and lockups and KASAN errors related to ax210 firmware crashes. One of the     KASAN dumps pointed at the tx path, and it appears there is indeed a way to double-free an skb. If     iwl_mvm_tx_skb_sta returns non-zero, then the 'skb' sent into the method will be freed. But, in case where     we build TSO skb buffer, the skb may also be freed in error case. So, return 0 in that particular error     case and do cleanup manually.

  - In the Linux kernel, the following vulnerability has been resolved: mmc: rtsx_usb_sdmmc: fix return value     check of mmc_add_host() mmc_add_host() may return error, if we ignore its return value, the memory that     allocated in mmc_alloc_host() will be leaked and it will lead a kernel crash because of deleting not added     device in the remove path. So fix this by checking the return value and calling mmc_free_host() in the     error path, besides, led_classdev_unregister() and pm_runtime_disable() also need be called.

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.

  - In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Fix potential null     dereference The adev->dm.dc pointer can be NULL and dereferenced in amdgpu_dm_fini() without checking. Add     a NULL pointer check before calling dc_dmub_srv_destroy(). Found by Linux Verification Center     (linuxtesting.org) with SVACE. (CVE-2023-53498)

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